Placenta Accreta: Brandy's Story

As part of Cesarean Awareness Month, we are drawing attention to the high cesarean rate and the public health implications of too many cesareans.

One of the complications of multiple cesareans is that the placenta in a subsequent pregnancy can implant too low in the uterus (placenta previa) or grow into the uterine wall (placenta accreta).

This can cause life-threatening complications, including premature birth, impaired growth, or stillbirth for the baby, and severe hemorrhage, hysterectomy, and even death for the mother. Placental abruption (placenta detaching too early) is another potential risk after a prior cesarean.

We've written about placental complications after cesarean before. As a brief reminder, there are three levels of severity in accretas:
  1. Accreta (placenta is abnormally attached to uterus and can't detach easily after birth)
  2. Increta (placenta grows into the wall of the uterus and cannot detach after birth)
  3. Percreta (placenta grown through the wall of the uterus and into surrounding organs)

[If you are looking for more technical information about placenta accreta, see Part One (what is accreta, how a placenta works), Part Two (risk factors, symptoms, and incidence of accreta), Part Three (risks to mother, baby, and future pregnancies), and Part Four (diagnosis and treatment) of my prior series on placenta accreta.]

This time, rather than writing about what accreta is and how to manage it, we present the first-hand story of one mother's experience with placenta accreta (increta in her case). 

It's important to remember that placenta accreta is real and affects real women and babies. Do enough cesareans, and increasing numbers of women will face this devastating and life-threatening complication. I've known several women now who have been affected by this condition; all suffered severe hemorrhages and several lost their fertility and uteri forever. One lost her baby and very nearly her life too.

That's why it's so important to do cesareans only when medically indicated and to keep VBAC (Vaginal Birth After Cesarean) an option for those who want it.

Brandy's Story

Brandy has had 7 births and 2 miscarriages. 3 of her births were by cesarean.

Yes, high parity is a risk factor for placental complications, but multiple cesareans is a stronger risk factor. Combine the two and the risks multiply.

Her first birth was a c-section after mismanagement by her doctor. She was told she'd never deliver a baby over 8 lbs. and that her babies were "too big" for her to deliver vaginally. She developed a terrible infection and wasn't allowed to hold her baby for 3 days.

Her second birth was a VBAC at 32 weeks. The placenta detached prematurely and baby might have had some lack of oxygen issues. He passed away at 21 months from seizures.

She miscarried her next pregnancy. Her third birth was another VBAC. She had to fight hard for it when her labor stalled for a little while but in the end she had a VBAC.

Her fourth birth was a CBAC (Cesarean Birth After Cesarean). She had a big baby (10 lbs.) and her doctor scared her into a repeat cesarean because of a recent shoulder dystocia in the practice.

Her fifth birth was another CBAC. Her doctor was opposed to a VBA2C. After her water broke and labor did not start for several days, she had the repeat cesarean. The doctor said she had very little scarring and could have more children. The risks of multiple cesareans, including accreta, were never mentioned.

In her next pregnancy, Brandy weighed the potential risks of VBAC after multiple cesareans against the cumulative risks of multiple cesareans and chose VBAC. She stayed at home in order to have a supportive provider. Her sixth baby was a homebirth VBA3C. He was 11 lbs. 4 oz., three lbs. bigger than her first doctor said she could ever birth vaginally.

She had another miscarriage again, then became pregnant a few months later. She planned another VBAC. Unfortunately, this time the fertilized egg implanted low, near the cervix (placenta previa) and the placenta grew into the uterine wall and into the cervix itself (placenta increta).

In the end she lost her uterus and most of her cervix and suffered a severe hemorrhage but was very fortunate to escape with her baby and her life.

This is the story of Brandy's placenta accreta pregnancy and birth.

I was so excited when I found out I was pregnant. I was also very scared since I had just miscarried 8 months prior. At 7 weeks when I started spotting I just knew something was wrong. I had no idea what the real problem was and what I would end up facing.

I decided to go to the ER and get checked. It was a pleasant surprise to see a healthy little heart beat. I did notice on my discharge paper that it was noted that the placenta had attached to the lower uterine segment.

A week went by and I was still spotting. I called my OB and they decided to schedule a ultrasound to check on things. The ultrasound tech noted that I had a short cervical length. I was sent to a perinatologist to see if they wanted to place a stitch. I was very confused. I had already carried 6 other children. I did deliver one of my babies at 32 weeks, but I never had a incompetent cervix.

The perinatologist quickly pointed out that I had a complete posterior placenta previa. I was so upset; I knew that would mean another c-section. I had already had 3 c-sections; I did not want another. I had already begun dreaming of another beautiful HBA3C. I had it in my head how I was gonna make a music list and dance through labor. I was gonna walk around outside in the nice cool October weather. I was looking forward to feeling every contraction and being more relaxed this time since it would be my 2nd HBA3C. [kmom note: Home Birth After 3 Cesareans]

Time went on and I continued to get ultrasounds monthly. It was always the same thing...the placenta had not moved. I was still spotting everyday; it was there every time I wiped. At one ultrasound appointment my OB made a comment that she saw a lot of placental lakes. I started researching placental lakes and learned that they are seen a whole lot with accreta. I started to worry.

I finally got good news at my 20 week ultrasound. The perinatologist said it looked like the placenta had moved and it was only the tip of it covering my cervix. He did say that there was a blood clot covering the cervix now, but that my body should reabsorb it. I questioned him a little bit about the blood clot. He reminded me that I had been spotting and that is what it was from. I had noticed the spotting had been slowing down so it all made sense. It was good news! The placenta moved some and I had a healthy baby boy. No one had to tell me I was having a boy; he decided to show off for momma.

I left the doctor's office practically skipping. I went and bought a bunch of "It's a Boy" balloons and filled a bag with them to let my other kids tear open. We were all so happy and back to planning our home birth.

At the next ultrasound I was 24 weeks and I just knew they were gonna tell me the placenta had moved more.  The look on the ultrasound tech's face said something was wrong. When she told me she wanted the doctor to see it I felt my stomach go into my throat. 

Two minutes felt like a century as the doctor was looking at the ultrasound. He said, “What I believed was a blood clot last appointment actually looks like a accreta.” He then went on to say that unfortunately with your c-section history and what this looks like, it I am pretty sure we will have to take your womb. 

He went on to show me how vascular one section of the uterus was. He continued to talk about unfortunately this is like the weather, there is nothing you can do about it. He continued to talk and all I heard was some mumble about any OB can do a hysterectomy and I should be able to deliver at my local hospital.

I was numb, how could this be. I waited at the check-out desk trying to breathe, trying not to cry. I got my card for my next appointment as the tears started to fall. I don’t know how I walked to my car. My phone rang and I could not get out hello.

After I had a little while to process things and talk to a few people I decided to go to get a second opinion in Baltimore. The blood clot theory made sense. My spotting stopped at 22 weeks.  I figured that was a good sign. The specialist in Baltimore knew more about accreta and could give me better answers.

Once I got to my appointment in Baltimore, that look the first tech had, I saw it all over again. This look of fear, maybe even confusion, just like the tech before she went to go get the doctor. He showed me that the placenta was supposed to look black on the ultrasound and there was these weird gray areas. He told me that at the least we were dealing with increta, but that he believed it was percreta. 

He went on to say all my care would be transferred there. That with this condition there would be massive blood loss and my local hospital could not handle delivering me. I tried to be strong but I burst into tears. We decided to do a MRI to try to get a better ideal if any of my other organs were involved.

Everything then just became a blur. I spent every Monday in Baltimore seeing doctors and having ultrasounds. The group of specialist were waiting on the MRI results to decide whether to deliver closer to 34 or 36 weeks.

Once the MRI results came back it looked like no other organs were involved but that the placenta was invading the uterine wall. I was so happy to get the news that none of my other organs were involved. That was the first time through all of this I got good news. It is funny looking back now how wonderful that news really was to me.  Since I was doing good and had no bleeds they decided to schedule my c-section at 36 weeks. Some of the doctors were still hopeful that once they got in there the placenta would detach easily.

I had 6 weeks until delivery and I was trying to understand and accept things. I was terrified. I felt like a ticking time bomb. I could not sleep. My husband was working nights so I was alone with 4 little ones, eight and under. I was scared I would have a bleed in the middle of the night and the kids would be terrified. When I did sleep I would have nightmares of having a c- section and my incision opening up and I was standing there holding my insides. 

I would hold my little ones and wonder if  I would be able to see them grow up. I would think, "My 2 year-old will not remember me." I think all these thoughts but had no patience with my kids. Then I would think if I don’t make it all they will remember is me snapping at them. 

One of the hardest things I had to deal with was knowing that the people that got me here by doing 3 unnecessary c-sections on me were the same people I now had to trust to get me out of this.

As the weeks went by I realized that I had no control over the outcome. I had to do the best I could and control what I could and give the rest to God.  I had to believe that even if I did not make it through that God would take care of my kids and it would be OK.

Days before my delivery I had to go do pre-op blood work and meet with anesthesia. I was told with the blood loss they were expecting I may have a lot of swelling and fluid in my lungs. They may have to keep me asleep until Friday until the swelling went down. They wanted my family to be prepared. That broke my heart to think I may not see my baby on the day he was born. They said I would go home with a bladder bag if they had to do the hysterectomy. With the scar tissue from my c-section they were sure that they would rip my bladder when they removed my uterus.

Delivery day came saying good bye to my kids was one of the hardest things I ever had to do. They were so excited to meet their brother the next day. And I had no idea if I would ever meet my baby or see my other kids again. 

I got to the hospital around midnight. They got me situated in my room and then let me sleep for a few hours. I would doze off for a few minutes then wake back up with a knot in my stomach and a lump in my throat. I didn't want to be there. I wanted to run far far away from that place.

At 6 a.m. they came in and started to get me prepped for surgery. We had decided that it was best for me to just be put under general. My surgeon was afraid he would lose time if I began to hemorrhage and they had to put me under then. They did not want the baby to be under general any longer then he had to. 

All the prep was done in my room. Anesthesia came and placed a central line in my neck and a large IV in my wrist; both of those were for blood transfusion. They also placed a monitor in my wrist that would send labs and gives them second-by-second blood pressure reading. By this time I was numb, I had shut down. I just prayed and sang worship songs in my head and took myself away from there.

My surgeon came in and did a quick ultrasound to see where he was gonna cut.  As funny as it sounds I was still hoping that he was gonna find that the placenta had moved.

Once it was time to go to the OR the two main surgeons wheeled me down. My husband got off on another floor to wait in the waiting room. I just wanted to scream, “NO!” I didn't want my husband to go. I wanted him there when I fell asleep. I just gave him a kiss and told him I will see you in little while. He said a quick prayer and slipped off the elevator.

We were outside the O.R. doors and had to wait. The blood bank had not brought down the blood that was to be on stand-by in the O.R. There were doctors everywhere. My neck hurt so bad from the central line. I could barely move. And there was so many people coming up introducing themselves. MY nurse kept saying, “Oh my goodness, everyone is here.” She said, "You have the best of the best!"

All of a sudden here comes two big coolers. I just hear everyone say, “OK, let's go.” My surgeon told me, "I have been resting for 2 days for your surgery." 

I said, “Hey, you have to take good care of me. I have lots of little ones that need me.” He said, “Brandy, we know what you got and we are gonna take good care of you.”

Things got real busy in the O.R., they put the oxygen mask on me, and kept telling me to to take nice slow breaths. The mask made me feel like I could not breathe. I was getting frustrated that I was not asleep yet. I wanted it over. No matter what the outcome was gonna be I was ready to get there. Everyone was rubbing my arms telling me that they were there and they aren't gonna leave, that I was OK. I remember thinking I am never gonna fall asleep.

I heard, "Don’t talk, you still have the breathing tube in." I raised my arm and started to write in the air. The nurse got me a paper and pen. I wrote "b" and dozed off, I wrote "a" and dozed off. The nurse said, "Are you writing 'baby'?" and I shook my head yes! She told me that he was healthy, 7lbs 2.5 oz. He had no problems and went straight to the newborn nursery.

They took the breathing tube out and I said, "Is it Friday?" and the nurse said, "No, it is Thursday, 2 in the afternoon!" I was so so happy my baby was OK and I was still here. It was finally over! The worry, the fear, the unknown!

My surgeon came and held my hand and  told me that they did have to do the hysterectomy, the main vein in the placenta had grew very deep into my cervix. They also had to take most of my cervix. I lost 7 ½ liters of blood. I was given 13 units of blood products. 

[kmom note: 7.5 L is 7500 ml. Normal blood loss in a vaginal birth is 500 ml; 1000 in a cesarean. She had more than 7x the normal blood loss for a cesarean.]

I didn't care at that point. I was alive, my baby was healthy! We made it to the other side. PRAISE GOD we were OK!

I met my little man when he was 8 hours old. He is perfect. I would do it all again to have him. We have both done very well recovering physically. I didn't need a bladder bag after all. I delivered on a Thursday and we came home together on Sunday. 

But emotionally it has not been so easy. I do sit here in disbelief sometimes wondering why me? Other days I get angry. I want to punch something and yell GIVE ME MY UTERUS BACK! I mourn the loss of my fertility, the loss of his birth and the first 8 hours of his life. The loss of my last pregnancy. The loss of some relationships that have been damaged through all this for one reason or another.

I share my story not to scare anyone. I know what it feels like to be scared into something. I would never want to do that to someone else. I just want women to be aware of all possible complications. I want women to be able to give true consent and be aware of all risks. 

If sharing my story saves one women from having a different ending than me then it wasn't all for nothing. Accreta is not talked about, but it is real, very real!

Preventing the First Cesarean: Don't Go to the Hospital Too Early

Dark line with squares is overall cesarean rate,
Light line with triangles is primary cesarean rate,
Line with diamonds that goes up and then plummets is the VBAC rate

As part of Cesarean Awareness Month, we are discussing the long-term implications of a high cesarean rate, as well as how to lower the sky-high cesarean rate in women of size.

One of the important parts of lowering the overall cesarean rate is preventing the first (or "primary") cesarean.

As you can see from the chart, the primary cesarean rate (middle line) has risen over the years pretty much in parallel with the overall cesarean rate, even as the VBAC (Vaginal Birth After Cesarean) rate has drastically declined.

The VBAC rate has declined so strongly because many places have VBAC bans in place. Once a woman has that first cesarean, she usually has repeat cesareans thereafter, unless she is one of the lucky ones who can find a provider that is truly willing to support VBAC.

Thus the first step to lowering the high overall cesarean rate is to prevent the very first cesarean from happening whenever possible.

And one important step in preventing primary cesareans is not going to the hospital too early in labor. 

Research has shown that when women are admitted early in labor ("latent" labor), they have a much greater chance of having a cesarean than if they get to the hospital a bit later, when contractions are consistent and dilation starts to change more quickly ("active" labor).

In fact, a recent consensus statement from the American Congress of Obstetricians and Gynecologists and the Society for Fetal-Maternal Medicine suggests that the definition of "active" labor be changed from 4 cm to 6 cm.

Lamaze International has highlighted this with their related discussions on "Six is the New Four."

This proposed change is based on research that suggests that labor tends to progress more slowly in the early stages of labor than recognized in previous guidelines, and that many "failure to progress" cesareans might be prevented by being just a little bit more patient during labor.

Below is yet another study that confirms the importance of not going into the hospital until labor is well-established and "active."

In this study, more than half the women were admitted during "preactive" labor, and those that were had more than twice the c-section rate of those who were admitted in active labor.

If half of women are regularly being admitted into the hospital during latent labor, this strongly suggests that delaying admission to the hospital until labor is truly in the "active" phase might help lower the primary cesarean rate significantly.

This may be a particularly important consideration for women of size. Some research suggests that "overweight" and "obese" women have longer labors, especially in the stage just before transition. Although no one has actually studied yet whether delaying admission until 6 cm in obese women would lower cesarean rates in that group, it certainly seems like a logical conclusion.

In combination with lowering unnecessary induction rates and being more patient in labor, delaying hospital admission until 6 cm might really help impact the cesarean rate in obese women.

Summary

The take-home message for mothers is that if you plan to birth in the hospital, don't rush to the hospital in early labor.

Obviously, if there is something that is concerning you or doesn't feel right, it's important to be evaluated, and you should not hesitate to go in and ask for evaluation. Certain other medical situations, of course, might also call for early evaluation; your care provider will help you determine the situations to be cautious about.

However, most of the time, there is no need to be in the hospital right away if labor has started. The sooner you go in, the more likely you are to have interventions like oxytocin augmentation and cesareans.

The take-home message for hospitals is to have stricter admissions policies, given that around half of women are being admitted in early labor. The secondary message is to allow more time in labor before moving to a cesarean (barring fetal distress); a "failure to progress" cesarean is too often a "failure to wait" cesarean.

Bottom line: To lower the rate of primary cesareans, wait till labor is well-established before going to the hospital, and practice more patience during labor before moving to a cesarean if all else is well.

INTRODUCTION: The timing of when a woman is admitted to the hospital for labor care following spontaneous contraction onset may be among the most important decisions that labor attendants make because it can influence care patterns and birth outcomes. The aims of this study were to estimate the percentage of low-risk, nulliparous women at term who are admitted to labor units prior to active labor and to evaluate the effects of the timing of admission (ie, preactive vs active labor) on labor interventions and mode of birth. METHODS: Data from low-risk, nulliparous women with spontaneous labor onset at term gestation were merged from 2 prospective studies conducted at 3 large Midwestern hospitals...RESULTS: Of the sample of 216 low-risk nulliparous women, 114 (52.8%) were admitted in preactive labor and 102 (47.2%) were admitted in active labor. Women who were admitted in preactive labor were more likely to undergo oxytocin augmentation (84.2% and 45.1%, respectively; odds ratio [OR], 6.5; 95% confidence interval [CI], 3.43-12.27) but not amniotomy (55.3% and 61.8%, respectively; OR, 0.8; 95% CI, 0.44-1.32) when compared to women admitted in active labor. The likelihood of cesarean birth was higher for women admitted before active labor onset (15.8% and 6.9%, respectively; OR, 2.6; 95% CI, 1.02-6.37). DISCUSSION: Many low-risk nulliparous women with regular, spontaneous uterine contractions are admitted to labor units before active labor onset, which increases their likelihood of receiving oxytocin and giving birth via cesarean. An evidence-based, standardized approach for labor admission decision making is recommended to decrease inadvertent admissions of women in preactive labor. When active labor cannot be diagnosed with relative certainty, observation before admission to the birthing unit is warranted.

OBJECTIVE: to explore the relationship between the degree to which labour is established on admission to hospital and method of birth...SETTING: a large tertiary-level maternity service in Melbourne, Australia. PARTICIPANTS: English-speaking women with no previous caesarean section at low risk of complications in pregnancy were recruited to a randomised controlled trial. Trial participants whose management did not include a planned caesarean and who were admitted to hospital in spontaneous labour were included in this secondary analysis of trial data (n=1532)... RESULTS: ...Pooling the two randomised groups of nulliparous women, and after adjusting for randomised group, maternal age and maternal body mass index, early admission to hospital was strongly associated with caesarean section. Admission before the cervix was 5 cm dilated increased the odds 2.4-fold (95%CI 1.4, 4.0; p=0.001). Augmentation of labour and use of epidural analgesia were each strongly associated with caesarean section (adjusted odds ratios 3.10 (95%CI 2.1, 4.5) and 5.77 (95%CI 4.0, 8.4) respectively. CONCLUSION: these findings that women allocated to caseload care were admitted to hospital later in labour, and that earlier admission was strongly associated with birth by caesarean section, suggest that remaining at home somewhat longer in labour may be one of the mechanisms by which caseload care was effective in reducing caesarean section in the COSMOS trial.

Impact of collaborative management and early admission in labor on method of delivery.
Jackson DJ1, Lang JM, Ecker J, Swartz WH, Heeren T. PMID: 12685666
OBJECTIVE: This study compared the effects of early admission in labor and perinatal care provider on delivery method. Higher spontaneous vaginal delivery rates for certified nurse midwives as compared with physicians have been reported in observational studies and randomized clinical trials. Certified nurse midwives, with their more expectant approach to labor management, would be expected to admit women later in labor than obstetricians. METHODS: Prospective cohort study of 2,196 low-risk pregnancies, with singleton, vertex infants admitted in spontaneous labor. Independent and joint effects of perinatal care provider and cervical dilation at admission on delivery method were evaluated... RESULTS: Fewer (23.4%) women in collaborative care were admitted in early labor (< 4 cm cervical dilation) than women managed by obstetricians (95% CI = -27.6 to -19.2). Obstetrician care had 9% to 30% fewer spontaneous vaginal deliveries. Women admitted early in labor also had 6% to 34% fewer spontaneous vaginal deliveries. Evaluation of joint effects suggested that interaction between obstetrician provider and earlier admission increased the risk of operative delivery. CONCLUSION:
Later admission in labor (at 4 cm or greater cervical dilation) and management of perinatal care by certified nurse midwives in collaboration with obstetricians increased the rate of spontaneous vaginal delivery in low-risk women.

Long-Term Implications of a High Cesarean Rate in Obese Women

April is Cesarean Awareness Month.

This is an annual observance sponsored by the International Cesarean Awareness Network (ICAN) to raise awareness of the implications of a high cesarean rate and lack of access to VBAC (Vaginal Birth After Cesarean).

It's always important to remind readers that this observance is not meant to make anyone feel bad about having had a cesarean, or to imply that having a cesarean makes you "less of a mother" or "less of a woman." Nonsense.

Cesareans can be life-saving and wonderful when used appropriately, but they are not risk-free. When over-utilized, they can have dramatic negative consequences too, especially long-term.

Cesarean Awareness Month is not about any one person's experience at all, but rather about the widespread public health implications of a high cesarean rate and lack of access to VBAC. And this certainly is an under-appreciated public health care issue.

Long-Term Risks of Too Many Cesareans

As we posted about extensively last year, one of the overlooked long-term consequences of a high cesarean rate is an increase in the risk for placental disorders.

Specifically, there is a substantial increase in the risk for:
Here is yet another study that confirms cesarean section as a strong risk factor for placental disorders.

Although this meta-analysis does not evaluate the risk by number of prior cesareans, merely by the presence of prior cesarean, a number of other studies have shown that the risk increases strongly with multiple prior cesareans in a dose-dependent manner.

This is why it is important not to have cesarean after cesarean unless it is medically necessary, and why the ban on VBACs in many hospitals is so frustrating.

The ban on VBAC (Vaginal Birth After Cesarean) in some places means that thousands of women have been and are continuing to be subjected to unnecessary cesareans. This in turn is raising the incidence of placental disorders like previa, abruption, and accreta, as well as maternal morbidity from the surgeries and the very serious complication of cesarean scar pregnancy.

Although with good care, many of these complications can be handled, they do often result in life-threatening hemorrhages, bladder or renal damage, uterine ruptures, hysterectomies, prematurity, stillbirth, and even maternal deaths at times.

Although these complications are overall rare, they are happening to real women, with real results, sometimes devastating ones.

This is why it is SO important to do cesareans only when truly indicated, to avoid automatic repeat cesareans, and to keep VBACs available as an option everywhere.

Implications for Women of Size

Long-term complications of cesareans is a particularly pertinent issue for women of size.

If a 32.8% overall national c-section rate is too high, then the rate in "obese" women is an even GREATER reason for concern because in most studies it starts at 30% and goes as high as 40%50%, 60%, and even 70% in some places and groups.

And many of the cesareans done in obese women are done without any labor at all. Many care providers have a de-facto policy of automatic "elective" cesareans for very obese women, despite the fact that this does not improve outcomes.

This disproportionately exposes the larger mother to the risks of cesareans (hemorrhage, infection, blood clots, bladder injury, and anesthesia problems) and subsequent placental disorders. This is insane. Yet few in the obstetric community even question the high cesarean rate in obese women.

This is why observing Cesarean Awareness Month is so important. It's not about putting down anyone who had a c-section, but to raise awareness of the health implications of a too-high cesarean rate.

In addition, it's time for care providers to focus on the implications of the sky-high cesarean rate in women of size and what can be done to lower that rate.

This is why I always observe Cesarean Awareness Month here and why I urge others to do so too.

Concern regarding the association between cesarean delivery and long-term maternal morbidity is growing as the rate of cesarean delivery continues to increase. Observational evidence suggests that the risk of morbidity increases with increasing number of cesarean deliveries. The dominant maternal risk in subsequent pregnancies is placenta accreta spectrum disorder and its associated complications. A history of multiple cesarean deliveries is the major risk factor for this condition. Pregnancies following cesarean delivery also have increased risk for other types of abnormal placentation, reduced fetal growth, preterm birth, and possibly stillbirth. Chronic maternal morbidities associated with cesarean delivery include pelvic pain and adhesions. Adverse reproductive effects may include decreased fertility and increased risk of spontaneous abortion and ectopic pregnancy. Clinicians and patients need to be aware of the long-term risks associated with cesarean delivery so that they can be considered when determining the method of delivery for first and subsequent births.

OBJECTIVE: The overall annual incidence rate of caesarean delivery in the United States has been steadily rising since 1996, reaching 32.9% in 2009. Primary cesareans often lead to repeat cesareans, which may lead to placenta previa and placenta accreta. This study's goal was to forecast the effect of rising primary and secondary cesarean rates on annual incidence of placenta previa, placenta accreta, and maternal mortality. METHODS: A decision-analytic model was built using TreeAge Pro software to estimate the future annual incidence of placenta previa, placenta accreta, and maternal mortality using data on national birthing order trends and cesarean and vaginal birth after cesarean rates. Baseline assumptions were derived from the literature, including the likelihood of previa and accreta among women with multiple previous cesarean deliveries. RESULTS: If primary and secondary cesarean rates continue to rise as they have in recent years, by 2020 the cesarean delivery rate will be 56.2%, and there will be an additional 6236 placenta previas, 4504 placenta accretas, and 130 maternal deaths annually. The rise in these complications will lag behind the rise in cesareans by approximately 6 years. CONCLUSIONS: If cesarean rates continue to increase, the annual incidence of placenta previa, placenta accreta, and maternal death will also rise substantially.

Wait for Spontaneous Labor If the Cervix Isn't Ripe


Here is a new study that suggests that it may be better to await spontaneous labor in first-time obese mothers with an unripe cervix, rather than trying to force labor to start regardless of the Bishop's Score.

Reference

Am J Obstet Gynecol. 2014 Jan 31. pii: S0002-9378(14)00063-5. doi: 10.1016/j.ajog.2014.01.034. [Epub ahead of print] Risk of cesarean in obese nulliparous women with unfavorable cervix: elective induction vs expectant management at term. Wolfe H1, Timofeev J2, Tefera E3, Desale S3, Driggers RW2. PMID: 24486226
OBJECTIVE: The objective of the study was to examine maternal and neonatal outcomes in obese nulliparous women with an unfavorable cervix undergoing elective induction of labor compared with expectant management after 39.0 weeks. STUDY DESIGN: This was a retrospective analysis of a cohort of nulliparous women with a vertex singleton gestation who delivered at MedStar Washington Hospital Center from 2007 to 2012. Patients with unfavorable cervix between 38.0 and 38.9 weeks (modified Bishop <5) and a body mass index of 30.0 kg/m2 or greater at the time of delivery were included. Women undergoing elective induction between 39.0 and 40.9 weeks' gestation were compared with those who were expectantly managed beyond 39.0 weeks. Outcomes were analyzed using χ2, Student t, or Wilcoxon rank sum tests as appropriate with a significance set at P < .05. RESULTS: Sixty patients meeting inclusion criteria underwent elective induction of labor and were compared with 410 patients expectantly managed beyond 39.0 weeks. The rate of cesarean delivery was significantly higher in the electively induced group (40.0% vs 25.9%, respectively, P = .022). Other maternal outcomes, including operative vaginal delivery, rate of third- or fourth-degree lacerations, chorioamnionitis, postpartum hemorrhage, and a need for a blood transfusion were similar. The neonatal intensive care unit admission rate was higher in the electively induced group (18.3% vs 6.3%, P = .001). Birthweight, umbilical artery pH less than 7.0, and Apgar less than 7 at 5 minutes were similar. CONCLUSION: Elective labor induction at term in obese nulliparous parturients carries an increased risk of cesarean delivery and higher neonatal intensive care unit admission rate as compared with expectant management.

Emergency Preparedness: Food Without Power

image from Wikimedia
We've been talking periodically about Emergency Preparedness and today we continue that thread.

Previously, we discussed preparing for the most common serious family emergency, which is a house fire. Then we talked about having enough water in an emergency, which is the first and most important prep to have. We've also talked about staying warm without power, having lights without power, and the importance of having emergency food and water reserves and emergency kits. We've also covered CERT (Community Emergency Response) Training and getting ham radio licensure.

For those wondering why I sometimes write about preparedness on a blog usually devoted to pregnancy/birth and size acceptance issues, emergency preparedness falls under the "parenting" and "healthy living" mission of the blog (see "About this blog," above).

Having lived in wildfire, tornado, blizzard and earthquake zones (as well as living not too far away when a major earthquake struck), I know how important disaster preparedness is, yet it's a topic neglected by so many people. I want to raise awareness of the importance of being prepared, with special attention to the preparedness needs of families.

Part of parenting is keeping your children safe, and the truth is that bad weather and disasters happen everywhere sooner or later. You can't guarantee a child's safety during a disaster, but you can greatly improve their chances afterwards if you are prepared. Many people die or are hurt after disasters due to poor conditions or lack of safe food/water, but much of this is preventable with good preparedness.

And of course, everyone experiences power outages at some point; it's amazing just how ill-prepared many of us are to be without electricity. Yet people die even during routine power outages because they cook food unsafely, get carbon monoxide poisoning, or inadvertently set their dwellings on fire. It's important to keep your children safe and as comfortable as possible, whether you are facing a major disaster or just a common power outage.

That's why today we are discussing how to feed your family during a power outage or an extended emergency where power and safe food/water may be scarce.

Preparing Food Without Power

The first step in feeding your family in an emergency is having plenty of ready-made food on hand that you can eat without cooking. Items like energy bars, beef jerky, fruit leather, nuts, trail mix, peanut butter, canned fruit, crackers, dried fruit, canned meat, and granola bars are all filling food that don't require any cooking. These are often enough for a short-term power outage.

However, if a power outage lasts for long, these foods get repetitive quickly, and a hot meal can be important for keeping up your energy, not to mention a great morale-booster. A hot meal also helps keep you warm from the inside. A little water, a few fresh or dehydrated vegetables, and a bit of canned meat, beans, or grains can be used to make a great soup or stew to warm you up and make you feel a lot better.

However, how do you heat it up? Sure, you can put a pot into the fireplace at your house, but what if you run out of firewood? What if you don't have a fireplace at all? It's important to have several ways to cook without power because you never know what circumstances you might be in.

The best answer for cooking without power depends on your circumstances, but options include:
Read more about these options from the links in the Resources section below.

Just be aware that most of these methods should only be used outside because dangerous fumes can build up (another reason for that carbon monoxide detector). Only the Sterno/Butane stove and MRE heater can be used to cook inside safely. (The haybox can be used inside, once the initial cooking has been done outside.)

Another limit to many of these options is that they depend on outside sources of fuel, which get used up pretty quickly in a power outage or emergency. That's why it's so important to have several options in your arsenal. You want to have multiple choices available to you when the chips are down.

Campfires and Fireplaces

In a power outage or emergency, many people are going to use their fireplace or a campfire for cooking. However, campfires and fireplaces, while handy, are not a very efficient cooking method. They use up a lot of fuel, take a long time to get to the cooking stage, and can easily burn the food. In addition, outdoor campfires are not very practical in bad weather.

Unless you are an experienced camper or Scout, you may not even know how to cook on a campfire. Packet meals (one dish wrapped up in heavy-duty tinfoil and roasted) are a good way to cook with fireplaces and campfires. You can read more about that here.

Image from Wikimedia
A cast-iron dutch oven is another great way to cook on a campfire. There are primers on cast-iron dutch oven cooking here, herehere, and here. They can be used with either wood fires or with charcoal.

The key is to heat your fire to the coal/ember stage, then put coals on top of the lid as well as below the pan. Then you are able to heat the food from all sides, which is more efficient. Don't forget that you can also turn the lid upside down on a fire and use it like a fry-pan.

While campfire and fireplace cooking can be a good adjunct to your preparedness plans, don't rely on it as your sole source of cooking in a disaster. It just requires too much fuel for frequent cooking and must be tended constantly. And campfires have to be done outside in a well-ventilated area, which may not work in some weather conditions.

So while campfires and fireplaces can be one tool in your preparedness toolbox, they shouldn't be the only tool there.

Camping Stoves or Barbecues

Image from Wikimedia
A backyard barbecue is a non-electric cooking source that most people already have on hand. As a result, they are often the most-used resource during a power outage. Most use charcoal or propane as a fuel source.

Portable camp or hiking stoves are the next most-used emergency cooking resource. There are many different types that use various types of fuels. You can read more about these options here.

Propane camping stoves are one of the best options. They are very portable, propane is fairly cheap, and you can store propane canisters ahead of time for an emergency. There are many different types of propane camping stoves available, so you can choose the type that suits your budget and needs.

Propane stoves have to be used outside due to carbon monoxide build-up, but the flames are adjustable so they are adaptable for many different types of cooking (stews, grilling, frying, simmering, etc.). They are also pretty lightweight and reasonably transportable.

Image from Wikimedia
Because many disasters or power outages occur during bad weather, many people attempt to use their BBQ or camp stove inside a garage or other enclosed area. This is deadly and kills people during power outages. Camp stoves and BBQs should only be used in open, extremely well-ventilated areas. If you have any doubt whether your ventilation is adequate, have a carbon monoxide detector nearby, just in case.

Remember that camping stoves and barbecues are useful only as long as you have fuel to power them. Have a good reserve of emergency fuel on hand, and have some other cooking options available in case your emergency goes on longer than your propane or charcoal supply.

Sterno/Butane Stoves, MRE Heaters


Image from Wikimedia
Sterno/Butane stoves and MRE heaters are great choices for cooking during a power outage since they are the only ones that can be safely used inside. This is HUGE during a winter storm! You certainly don't want to go outside and freeze in order to make warm food, which is what you have to do with most other emergency cooking options.

If you live in an area where cold or bad weather might be an issue, these options should be part of your emergency preparation. They can be found online, at restaurant supply stores, Asian food stores, or at camping stores.

Sterno is a solid alcohol fuel that comes in little cans. You open the lid, light it, and use it to warm food set on a grill or screen above. You extinguish it by simply sliding the lid onto the can. Caterers often use Sterno to keep buffet food hot at special events. At our house, we use it for cheese fondue (a family tradition in my husband's family). Many people also use it with chafing dishes, to keep food warm during parties or picnics.

Sterno fuel is basically denatured, jellied alcohol. It comes in small cans; a small 7-ounce can lasts for about 2 hours of continuous burning. It is very affordable; a 7-ounce can costs about $3, or you can buy a set of cans at once and get a volume discount. Keep the fuel away from little ones, though, since it is toxic.

Sterno stoves work well for heating up small meals like canned soup or stew. You can't easily control the flame intensity or heat, though, so they do not work as well for cooking meals from scratch, grilling, or getting the internal temperature of meats into the safe zone, etc. But for the re-heating common to most emergency cooking, they are just the ticket.

Image from Big5sportinggoods.com 
Butane stoves are a nice alternative to Sterno stoves. They are often used for powerless cooking during catering events, and frequently used for table-side cooking at various Asian restaurants.

A good Butane stove allows more flexibility in flame control and temperature than Sterno cooking, so it is a better alternative for cooking things from scratch and cooking meats, whereas Sterno is best at reheating pre-made foods.

Like Sterno, Butane stoves are safe for cooking indoors. Butane canisters are very affordable (slightly cheaper than Sterno) and last about the same as Sterno cans. On the other hand, Butane is more volatile and must be stored carefully. It also does not perform well under cold conditions.

Image from Wikimedia
MRE (Meals Ready to Eat) heaters are what the military gives to soldiers to heat food up out in the field. They use a combination of chemicals (iron, magnesium, and salt) that when mixed with water, create heat in an exothermic reaction. Their big advantages are that they provide flameless heat and are small and portable.

While they take a while to heat up and don't heat much more than some water or a one-person meal, MRE heaters can be useful as an addition to Sterno/Butane stoves because they too can be safely used inside.

Like camping stoves, Sterno/Butane and MRE heater options are only useful as long as the fuel lasts. Therefore, have a bountiful supply on hand in case your power outage/emergency lasts more than a couple of days. Use other back-up options like campfires or camp stoves during the day so you can keep your Sterno/Butane for priority times (like at night, or during in bad weather).

While these stoves are promoted as safe for cooking inside, some authorities still recommend having a working carbon monoxide detector in the room with you, just as a precaution.

Rocket Stoves

Image from Wikimedia
Rocket stoves are an excellent emergency cooking option, although they are a bit pricey.

Rocket stoves (including brands like StoveTec and the Ecozoom) are super-efficient portable stoves that use an insulated L-shaped combustion chamber to cook foods quickly and easily. They don't take much fuel because the design is so efficient.

The best Rocket or Volcano stove models can cook using just about any biomass, including twigs, pine cones, dried corn cobs, pine needles, and other small items that normally wouldn't get used for a fire. This means you can cook without needing big logs or lots of firewood, and a lot less energy is wasted. This efficiency is a huge advantage in an emergency.

The disadvantage of rocket stoves is that they must be used outside, and even though they are far more efficient than a campfire, they do take biomass and must be tended constantly. They are also pretty expensive for an initial purchase, and are fairly heavy to lug around.

Image from rootsimple.com 
You can buy expensive, super-efficient rocket stoves online, or you can build your own pretty easily with #10 cans (coffee cans). You can read more about that here, but remember that your own will not be nearly as efficient as a professionally-built version.

If you have the money to buy one or want to build one, rocket/volcano stoves are a great option for powerless cooking. They really are astoundingly efficient and their ability to use small amounts of biomass make them extremely flexible in an emergency when traditional fuel may be scarce.

Haybox Cooking

Image from Mother Earth News
Hayboxes are basically a heat retention thermal cooking method. They use the initial cooking heat to continue the cooking process inside an insulated container without additional fuel. Hayboxes can be a useful addition to emergency cooking because they minimize the use of fuel. It's like a non-electric crockpot on steroids.

Basically, you begin cooking your food in the usual way, by bringing it to a sustained brisk boil over a campfire or portable stove of some kind. However, once the initial cooking has been done, you remove the pot from the heat source and put it inside an insulated cooker, box or bag. It works like a thermos, except that the initial heat of the food combined with really efficient insulation keeps the cooking going inside the pot. In time, the food will finish cooking on its own.

Hayboxes got their name from the fact that early versions often used a box filled with hay for heat retention cooking; sometimes they were buried in the ground for another layer of insulation. Although they have been around for many years (medieval cooks used them), hayboxes became popular again in the modern age during World War II to conserve rationed fuel.

Wonderbag instructions
Hikers and backpackers have used a variant of a haybox for years, starting up a soup in the morning, placing it in a sleeping bag or other insulator during the day, then coming back to a hot meal at the end of the day. In Asia, thermal cookers (like a haybox, but with more modern insulating materials) have become very popular in recent years. And insulated cooking bags like the Wonderbag are now being distributed in Africa to improve conditions for third-world families there.

The biggest advantage of haybox cooking is that it can save significant amounts of fuel. Fuel is only used for the initial heating, not the whole cooking time.This is a huge advantage in an extended emergency or power outage when alternative fuel sources (like propane) are limited and will not last that long.

Another advantage is that the prolonged cooking makes for more tender meat and better flavor, which is why Cantonese cuisines in particular favor thermal cookers. In addition, haybox cooking can lessen exposure to smoke and toxic fumes from cooking fires, which can be a significant advantage in third-world countries. It also saves water because less water evaporates out of the dish, another advantage during an emergency when drinkable water may be scarce.

The disadvantage of haybox cooking is that it takes a long time. Cooking a soup or stew usually takes about 3x the amount of time it would take on a stove. This means you have to plan ahead and there is less instant gratification when you are hungry. However, it also means that you can start dinner in the morning, leave it to cook while you do other tasks, and then come back to a hot dinner. There's no need for someone to stand around and tend the fire or stir the pot.

A potential disadvantage of haybox cooking is food safety. It's not always easy to know when meat is cooked enough to remove from a primary heat source and put into the haybox to finish cooking. And if the food is left in the haybox too long, it may eventually cool out of the safety zone and bacteria could start to grow.

As a result, you might want to ensure that any meat you use is cut into smaller pieces and cooked pretty thoroughly before transferring it to the haybox, and that you leave the food for several hours in the haybox to be sure it is thoroughly cooked. If you are uncertain about its safety, you may want to use a food thermometer to check the internal temperature before eating. If the food has cooled a bit, you may want to re-heat the food to the boiling point before serving it. There are guidelines for pre-cooking times available in some thermal cooking kits that may help you to feel more secure with this process. As long as you use common sense, it should work fine.

http://www.83rdsheffieldguides.co.uk/1_42_Making-a-Hay-Box.html 
You can make your own haybox, or you can buy a pre-made bag or thermal cooker. Professional vacuum thermal cookers are quite expensive ($150-200) but are extremely efficient.

Wonderbags can be bought for around $50 and the nice part is that one will be donated to a third-world country as part of the price of your purchase. Or if you are handy, you can sew your own version.

Hayboxes can be made very cheaply out of a box and materials you may have around your home but may not be quite as efficient as professionally-produced ones. In a pinch, you use a picnic cooler and some wool blankets or quilts around a good metal pot, but better ones take a little more construction.

If you want to make your own haybox, choose a box that is somewhat larger than the pot you will be using. Line it with paper, tinfoil, emergency survival blankets, or other similar material if it has any gaps. Or use a picnic cooler or ice chest box, since that is already quite well-insulated.

Image from Fireless Cooking, link below
Some people even make boxes with openings for two separate pots, so they can cook multiple dishes at once. A hall bench or toy box might be adaptable for this purpose.

Once you have your box, fill it part-way with insulating materials. Choose materials that will trap air for more efficient heating, like hay, shredded newspaper, Styrofoam packing materials, cotton batting from furniture or pillows, quilts, wool, moss, or sawdust. Don't pack the materials in super-tightly; it is the air pockets that are the key to the insulation, as in a down quilt.

Hollow a spot in the insulation for the pot, then line the whole thing with a piece of fabric, stapled to the walls or outside. This will help keep the insulating materials from accidentally getting into your food. Then fill a pillowcase with insulating materials to go around the top of the pot. The fit should be snug around the pot but enable the top to close without any gaps.

Choose a pot that will maximize heat retention, like cast iron, copper, or steel. A cast-iron kettle (like you'd use for camping) is perfect for the task. Use a pot with a short handle and a tight-fitting lid; simmer with the lid on so the lid is pre-heated too before transferring it to the haybox.

Image from Wikimedia
Soups and stews are perfect for haybox cooking, as are beans, grains, and similar foods. Or you can cook breakfast cereals overnight in a haybox and have a hot breakfast ready in the morning immediately upon rising. You can also pre-heat water overnight for tea or hot chocolate, which is nice quick warm-up in the morning if the power is out and the house is cold.

Recipes for haybox cooking can be found here, here, or here. Remember that because you are cooking with retained heat and steam, there is less evaporation during cooking, so use slightly less water in your recipes than normal.

There is a book from 1913 on Fireless Cooking that can be downloaded for free from an archive because it is no longer under copyright. It has detailed instructions and recipes that can be used for different types of hayboxes, including the double-haybox seen above.


Solar Ovens

Image from Wikimedia
Solar cookers are a great resource for truly "powerless" cooking. Like a haybox, you start them cooking in the morning, and your meal is waiting for you that evening.

There are several different kinds of solar cookers, from solar box cookers to parabolic cookers to solar panel cookers. To learn more about solar cookers, click here or here.

The advantage of solar ovens is that they use NO fuels at all, just the free power of the sun. In a long-term power outage, they are probably the most useful method of cooking available because you'll never run out of fuel. You can still cook, even if you are all out of propane, Butane, Sterno, and firewood. In addition, solar ovens can pasteurize water as well, making it safe to drink without using any fuel or chemicals.

The disadvantage of solar ovens is that they depend on having enough sun. In some areas of the world, that's a challenge. And of course, they can only cook during the daytime, not at night.

And even when you do have sun, the angle of the sun changes throughout the day. Therefore, solar ovens work best when someone is around to change the angle of the solar oven periodically throughout the day in response to the path of the sun. That may not be practical, especially in an emergency situation. However, on a good sunny day, most meals will cook just fine even without optimal sun angles. It is only on partly-sunny days that babysitting the solar oven may be important.

Professional-quality solar ovens can be pricey. They are worth the money if you have abundant sun in your area and might be able to use it frequently. However, a less-efficient version can also be made from scratch. Here is a video of one you can make yourself for about $5.

A homemade solar oven is worth making if you might use it only occasionally. However, the well-engineered and super-efficient professionally-produced ovens are worth the price if you plan to use them regularly or if you don't have enough money for a large stash of alternative fuels. You can find a comparison of many different solar oven brands here.

Because solar ovens are dependent on having decent sunshine, it is important to have other back-up cooking options for times when sunshine is not available. However, solar ovens are so versatile that they are an excellent addition to emergency cooking choices if you live in a high-sunshine area of the world.

Summary

There are many ways you can cook during a power outage or other emergency.

It is best to have several cooking options available to you so that you are not dependent on any one method.

A Sterno or Butane stove is probably the most desirable because you can re-heat and cook safely inside during bad weather  or at night. You don't want to have to stand on your back patio in freezing weather or pouring rain in order to feed your family. Although much of your cooking will probably be done outside with other sources, you do want to have an indoor option for when conditions are not hospitable.

Next most handy might be a camp stove or a rocket stove. This will probably be your first choice for outside cooking during the day and when conditions are good. Combine that with a haybox (start it on the camp or rocket stove, then finish it in the haybox), and you can stretch your fuel reserves most efficiently.

Additional options include campfires, fireplaces, backyard BBQs, and solar ovens. Which is most useful to you depends on your unique circumstances. Develop a plan that addresses your situation and gives you several options to choose from.

In addition to cooking equipment, there are other things you need for cooking without power.

For example, if you are planning on re-heating canned foods, don't forget to have a couple of manual can-openers on hand. Have plenty of batteries to power flashlights, headlamps, and lanterns so you can see to cook when it gets dark.

Consider having disposable dishes on hand too. Although it's wasteful to use paper cups and plates in everyday life, using them in an emergency is only common sense. Paper plates are burnable and won't require you to use up precious fuel or waste potable water for dish-washing. A dollar store is often a good, cheap source for paper supplies like this.

In order to fix meals without power, remember that you will also need to have a good reserve of drinkable water. Soups and stews are the best recipes for emergencies but need lots of water, and any freeze-dried or dehydrated foods need water for reconstitution. Most experts recommend at least 1 gallon per day for each member of the family just for drinking; you may need a bit more for cooking as well. Store enough for pets too.

5-gallon or 7-gallon portable camping containers work well for storing water reserves. Store enough for at least 3 days at a BARE minimum; 1-2 weeks is a much more sensible amount. Then have a way to filter and purify water so that if your emergency goes on longer than a week or two, you can make other water safe to drink.

Use your fuel sensibly. If you are already heating up food, boil some water at the same time and put it into some good thermoses for later use. Wrap the thermos in insulating material (like a tea cozy) to help it keep warm longer. Use the heat to fill hot water bottles or make heated bricks, which can help keep you sleep warmer too. If you are going to burn fuel, make it work in as many ways as possible for you.

Finally, think through the potential emergencies in your area and how long it might take to get help. Although most power outages last only a few hours to a couple of days, many areas of first-world countries have had to go weeks or even months without power at times. Have enough food and water reserves and a multitude of creative ways to cook so that you could last that long if needed. Don't rely on only one method; have several possibilities ready so that you have back-up if one type of fuel runs out or doesn't work. Or as some people put it, "Have back-ups for your back-ups."

Being ready to feed your family without power is all about creativity, having a good food and water reserve, and having multiple cooking options available to choose from.
