Home Births and the Courts

-->
My third child, Yeshe, was born at home after such a gentle labor that her amniotic sac or caul was intact!  I was attended by two amazing midwives---my care during pregnancy, delivery, and postpartum was the best medical care I have ever received.  Yeshe was born at term and her unbroken sac (this it means my water never broke during labor or delivery) is such a portent for good luck & special powers that midwives honor this type of birth. And 19th century New England households used to keep these cauls in jars on mantelpieces in houses where their seafaring men were out to sea for safety.  Yeshe's name means wisdom in Tibetan, and her namesake was my teacher at the Karsha nunnery where I have lived and worked on/off for the 29 years, since 1989 (see my book: Being a Buddhist Nun, Harvard University Press 2004). 

Yeshe's birth gave me much pause in May and June of 2017 when I was forced to retell the story of her birth in a courtroom in front my ex (who lied and fabricated the details of her birth and immediate postpartum period), his lawyer, my lawyer, and audience of 3 friends and family I'd summoned for the day. Ashok, interestingly, had nobody present to support him in the courtroom, perhaps aware that his lies might be caught out by friends who know me and Yeshe's birth story. Here is a rough account of what I said under oath wrote and in a written rationale submitted to Judge Simmonds of Berkshire Probate Court in 2017:

Yeshe was born at home with the assistance of a trained and certified midwife with 30 years experience, who examined her at birth and again 24 hours later and found a healthy newborn with no jaundice.  At 48 hours after birth, a lactation consultant found Yeshe to be jaundiced, but this was hardly unusual given that jaundice affects 50% of all newborns born at term.  She advised us to have Yeshe's billirubin checked at the hospital or, if we preferred, she would return the next day to see if the jaundice was progressing or improving.  When she returned the next day and the jaundice had progressed, we took Yeshe to our pediatrician, Dr. Art, who confirmed severe jaundice and urged us to have blood test because she suspected Yeshe might have hyperbillirubemia due to a rare blood disorder called ABO incompatibility (blood incompatibility between mother and baby.)

First, ABO incompatibility 
affects less than 5% of all newborns in the US, and tends to manifest at 48 - 72 hours after birth. In short, most newborns who have this condition are asymptomatic at birth. 

Second, most of the 4 million babies born in US hospitals were not routinely screened for ABO incompatibility in 2007

Third, if Yeshe had been born in a hospital she would have been discharged. My midwife's son was born at Cooley-Dickinson hospital in Northampton with ABO incompatibility, and discharged one day after birth with no jaundice. At 2 days after birth he was brought back to the hospital by his own mother but nobody ever questioned her medical decision nor that of the hospital that discharged her son..

Fourth, Yeshe’s home birth was attended by a licensed midwife and she had no clinical signs of severe jaundice or ABO incompatibility at birrh, nor one day after birth when the midwife conducted her routine check up. 

Fifth, there was nothing about Yeshe's home birth or the midwife's care that caused Yeshe's jaundice. It was caused solely by the congenital ABO incompatility that had nothing to do with mode or site of delivery.

After Yeshe's lab test, we went home and waited for Dr. Art to call us with results on our home phone---we didn't have cell phones in 2007.  Because Ashok had turned the ringer off, we only checked our machine an hour after Dr. Art called.  I wanted Ashok to drive me to the hospital immediately, but he wanted to wait till my mother arrived to stay home with our twins, as it was Jan 2 and -10 F outside that day.  When we did arrive at the hospital, Ashok blamed our delay on me I later learned from parsing the medical notes and that was all Dr. Art needed to distrust me from that point onwards.  

Yeshe was admitted,  given an IV to avoid dehydration, and given phototherapy for two days until discharge 48 hours later. Upon discharge, we were given a home phototherapy device that we used a few more days. Yeshe experienced no sequelae of this incident, but Dr. Art was traumatized---perhaps because she was a new doctor and had seen so few cases of ABO incompatibility--shame on you Stanford Medical School for not preparing her betterD!---or perhaps  because she would subsequently alter medical records about this incident 10 years later in 2017, just days before our trial, so that the medical record would better reflect an email filled with mistakes and lies that she would submit in Ashok's defense to the court in April of 2016. In short, she was traumatized by her own role in helping a Judge award legal custody to my abusive ex. 

Ashok's oral testimony was so full of confusion and lies it perpetuated the Judge's suspicion about my medical decision.  Ashok accused me of not having Yeshe's billi levels checked at birth--patently impossible as Yeshe was born at home and a billi test requires taking blood and a sophisticated laboratory analysis that can take hours. Ashok's attorney, Diane DeGiacomo also asked Ashok during his oral testimony, “did a doctor test Yeshe's billi levels at birth?”  This question is absurd given Yeshe was born at home and there was no doctor present--doctors have not been present at home births for nearly a century!   In short, Ashok and his attorney were accusing me of not having an intervention at home that was not even routinely prescribed in hospital births!  Neither the judge nor any of the attorneys noticed.   

Ashok was so confused in court he brought up my breatfeeding of Yeshe during her 48 hour stay in the hospital--not quite realizing I was doing what the doctor ordered and what was lifesaving at that point. What he failed to note was that Yeshe's IV had fallen out the first night in the hospital and so breastfeeding was the only way to keep her hydrated and alive, failing insertion of another IV, which could have further side effects--infection and stress.  Further, if that IV fell out, Yeshe would need a transfusion and transport to the Springfield NICU 2 hours away.  

There is only one major and deadly side effect of phototherapy treatment, namely dehydration.  If a newborn is not given an IV or breastfed, the phototherapy lights––which are so intense that newborns wears black foam glasses so as not to suffer retinal damage and routinely get sunburned––are deadly for newborns whose systems are easily shocked by disturbances of warmth, hydration, and nutrition.  The nurses on shift understood the urgency of my breastfeeding every few hours to keep her hydrated, but Ashok described it as problematic to a Judge and a courtroom that had almost no understanding of neonatal health or survival. 

In an email submitted to the court as well as to the court-ordered GAL who was investigating our case for a year, Dr. Art would argue that Yeshe's case was one of the 'most traumatic moments' of her career.  She may have meant the longer term effects of her decisions, as well as her choice to first lie and later change Yeshe's medical records 10 years later, deleting entire pages and changing notes in relation to Yeshe's billirubin incident and her subsequent asthma. In short, Dr. Art needed Yeshe's medical record to more closely reflect the email she wrote defending my abusive ex, Ashok, and guaranteeing that the Judge would award Ashok legal custody months after our trial.  

Things got even more complex when Dr. Art found out that Ashok had lied to her office about his ongoing physical abuse of our our son Krishan since 2014 (violent shoving, pushing him off the porch, slamming him into walls, kitchen counters, stoves as recently as June 2018).  Rather than admit to how her suspicions about homebirth had muddied the waters and caused her to distrust me, Dr. Art discharged all 3 children from her care, when I pointed out the numerous--and there were over 50 at last count---places that she had changed the medical records shortly before they were subpoenaed by the court in April of 2017 and again in September of 2016 when I finally shared with her the history of Ashok's abusive behavior.  

Why does this story matter? 

It was as if I had a scarlet letter on my forehead during that trial--only H for homebirth---rather than A for adultery.  

If you have a home birth, your Pediatrician might actively work against you for the next decade of your children's care 
In fact, she might even support an abusive ex who is physically assaulting your children. 

Dr. Childsy Art, never trusted me again after I had a home birth, and seemed to forget that I stayed home for two years taking my twins to every medical appointment, developmental check ups (the two most important of which at Dartmouth Ashok failed to even attend), weekly and daily developmental therapy with in house  physical and occupational therapists prescribed by her office.  She knew I studied neonatal and maternal health, as well as midwifery care.  

Once the Judge and Ashok's attorney knew I had a home birth, I was already suspect.  It did not matter that I have been studying neonatal and maternal health for 20 years, blogging for 14, written several published essays, and currently writing two books on maternal and neonatal health. I am editing my next book, Sustainable Birth, with  two amazing women, Robbie Davis-FLoyd and Betty-Anne Daviss, who are writers, speakers, and front-line advocates for midwives and home births for more than 35 years now. 

It is only by telling the truth that we can hope to bend the arc of justice away from lies and misunderstanding.  dedicate this book and my work to birth activists around the world who 
fight to given women healthy choices around birth even as courts and doctors in our medical-industrial complex obstruct take away those choices every day....

Twin Study

In 2007, the British Medical Journal (BMJ) reported that second-born term twins are twice as like to die at birth or shortly after birth as first born twins, if delivered vaginally. This finding reflects a relative risk, not an absolute risk which remains very small, and it was for term births only.

The Atlanta Journal Constitution (3/2/07) reported:
"'I would hate to see this study used as an excuse to have every mother with twins have a Caesarean section,' said Dr. F. Sessions Cole, the head of the neonatal intensive care unit at St. Louis Children's Hospital." Dr. Cole also that the study may apply more to Britain than the US, because we monitor twins better here.

Today, many doctors are all too willing to follow the lead author of the BMJ study, who concluded that: "the findings of this and other studies suggest that planned cesarean section may be beneficial for all twins."

The key word is MAY. Medical opinion is divided on whether cesareans are protective for all twin deliveries. Two French studies from 2006 and from 2003 showed excellent outcomes for vaginal deliveries of twins, regardless of presentation.

So why are so many doctors afraid to deliver twins vaginally? Because of a hostile legal climate in which a public expects a perfect birth and is unwilling to accept the very real risks of breech and twin deliveries, regardless of mode of delivery. When something goes wrong, when the doctor can show a cesarean was ordered, patients rarely complain.

Today, between 50% and 90% of all twins were delivered by cesarean, depending on their orientation (ie. headfirst or not). Yet roughly 60% of all twin pregnancies includes one twin who is not headfirst. This amounts to more than 80 thousand babies a year in the US, many if not all of whom will be delivered by cesarean.

Pregnant with breech twins in 2004, I had great difficulty finding a doctor willing to consider a vaginal delivery. Even though the studies were not conclusive in my case---for it was the second not the first twin who was breech---every single OB balked, even those in midwifery practices, even those who touted themselves as pro-vaginal delivery. Ironically, I delivered my twins an IVY league research hospital with the one obstetrician willing to deliver breech twins vaginally---at 26 weeks. None of the maternal fetal specialists at Harvard, Yale, or Northwestern I have since interviewed would have considered such a move. I still wonder if my twins success in the NICU had something to do with the well-known fact that labor and vaginal deliveries are known to hasten lung maturity?

It will be interesting to see what happens when the next generation of OBs and neonatologists take over, few of whom recall an era when any twins (never mind breech or preterm) were regularly delivered vaginally. For now, I hope that medical residents keep reading studies from other countries where doctors still perform vaginal deliveries of twins and breech babies, before these skills are utterly lost to history.

Jul 12, 2010

The delivery room at a district hospital in northern India was as crowded as the Palden Lhamo chapel during one of Ladakh's biggest winter festivals, the annual Spitug Gustor. It was only 10 am and it was standing room only. Dr. P, who had just gotten off the plane from Delhi that morning, waited as a woman whose bare thin calves poked out from under a bulky North Face jacket climbed up on the rusty steps to the delivery table. The jacket was a logical outfit. It was early April and nighttime temperatures inside the hospital might well sink into the 50’s.

Chime had arrived in early preterm labor at 3 am already 3 cm dilated and there was little the staff could do to slow the labor. There is only one doctor on call at night for a district hospital that serves a region one and half times the size of Denmark. In this case, the doctor, an internist with no experience in obstetrics or pediatrics was unfamiliar with the protocol for tocolytics to slow a woman's labor or prenatal steroids to help speed up fetal lung maturation. As a result, by the time Dr. P saw her, the patient was 10 cm dilated, 100% effaced, and her amniotic sac about to burst.

Which it did did as Dr. P performed her internal exam. She grimaced as the dark meconium stained fluid splashed over her pants and onto the floor. The color of the amniotic ‘liquor’ indicated possible fetal distress and were grounds for immediate delivery, she later explained. Yet she was concerned as the ultrasound from the previous night indicated a gestational age of 29 weeks and the patients’ chart suggested an even earlier date of 26 weeks.

P told Chime her baby had only a 15% chance of survival at this point and that the baby should be born as quickly as possible. I was reminded of my own precipitous labor almost 3 years earlier when I saw the terror in Chime's eyes. I, too, had found myself in a hospital in an emergency labor, with my waters broken, far earlier than I ever expected. I, too, was in labor when I was warned uncertain prospects my twins would face at 26 weeks. While I'm glad I was told the truth, I don't think there is any easy way to break this kind of news to a woman in preterm labor.

Dr. P immediately called for an IV and oxytocin, which might speed up the mother’s labor and also prevent post-partum hemorrhage, one of the most common causes of maternal death in both India and Tibet. A nurse placed the catheter, which failed to drip, until Dr. P noticed and cleared a dangerous bubble in the IV line, and then injected the syringe of synthetic oxytocin into the IV bag dangling above Chime’s head. The dose she administered---less than 1 mililiter of oxytocin per liter of IV saline----was lower than the standard US low dose oxytocin protocol that is used in over 70% of births in the US.

Yet even these protocols can be problematic. The Wall Street Journal 97/21/2006) reported that even insurance companies are trying to reduce the over-reliance on synthetic oxytocin or Pitocin in American obstetrics, as the drug is implicated in over half of all obstetric malpractice claims that involve birth trauma. These claims make obstetrics one of the most claim-ridden and costliest specialties in medicine from the perspective of insurance companies.

Chime tired after two hours of pushing ---for she been up the entire night in the throes of labor, then traveling to the hospital, never mind the panic of what must have felt like a horribly wrong time to be having this baby. But with Dr. P's encouragement and the nurses scolding, she managed at last to push her son out.

When her son was finally delivered, he was much bigger than expected at 1.6 kilos, but almost non-responsive. His color was dusky, he wasn't breathing, and had no obvious reflexes. His apgars of 2,4, and 6 at one, five, and ten minutes, reflected the concerted efforts of the hospital’s best obstetrician and pediatrician. He was transferred back to packed obstetric ward a half an hour after birth and given best treatment the Leh hospital had to offer---100% oxygen by improvised nasal canula, suctioning, and intramuscular antibiotics. Less than 24 hours later, he died of a brain bleed; his mother was discharged the same day.

Why write about this incident?

Because giving birth involves very similar and very different forms of suffering for women and infants, each and every day, depending on where they live on our crowded little planet. I honor the suffering that women in Ladakh experience who have no access to NICU's as much as I respect the difficulties that women in the US face, with some of the best medical care in the world.

Two Births, Two Twins, Two Boys.

Two boys, both twins, my son on right, my friend N's son on left.
Two boys: the one on the right is my son and the one of the left is my friend N's son. Both were born vaginally and both were part of pair of twins one of whom was breech. But there the similarity ends.

N delivered her twins at term and at home in rural Zangskar at 12,000 ft. She was attended by her sister, a midwife, and the local pharmacist. My son and daughter were delivered at 26 weeks in a stainless steel operating theatre at Dartmouth hospital, attended by no less than four obstetricians, several obstetric residents, three anesthesiologists, two neonatologist, a few neonatology residents, and a dozen nurses.
N's labor and delivery took all of six hours. I was in early labor for four days and active labor for 27 hours, with an obstetric team that was willing to be as patient as modern obstetrics would allow.

N received a single shot of muscle relaxant called epidocin (valethamate bromide) used to relax the cervix and speed up dilation. When I asked to deliver my preterm twins naturally, the doctors looked at me with pity or morbid fascination. Despite resistance, I received the following drugs: magnesium (accidentally) to slow my labor (abandoned once it emerged an amniotic sac had broken), antibiotics to prevent infection (habitually used for preterm births), IV fluids for rehydration (no evidence of benefit other than the ease of administering further drugs), steriod shots to hasten fetal lung development (good evidence of benefit), pitocin to speed up my labor (painful, mixed evidence of benefits), and an epidural just before I pushed my first twin out (anecdotal evidence, as my OB insisted that she didn't want me crawling up the operating table like a former patient as she reached into my uterus to pull out the second twin, who was breech).

If I had delivered my twins in Zangskar, they would have had little chance of survival. If Nyima had delivered her twins in the US, she would have had trouble finding a midwife willing to do a homebirth for twins and no chance finding a doctor willing to do a vaginal delivery where the first or presenting twin was breech. It was luck that I, not she, had the antenatal hemorrhage. Roughly half of all maternal deaths in Nepal and a third of maternal deaths in India and Tibet are due to hemorrhage, and even in the US, hemorrhage remains a major cause of maternal death. Rather than enumerating statistics, let't turn to N's delivery in the rural Himalaya.

***

Neither N nor her sister Lhaskyid, the midwife, was sure N was having twins nor a breech until the day of her delivery.

When L performed her first internal exam, shortly after N went into labor, she discovered two things in rapid succession. First, N was already ‘two fingers’ (3 cm) dilated after only an hour of labor. But the real surprise lay beyond the cervix. Rather than the comforting roundness of a head, she could feel buttocks. She nearly cried out because this baby was not headfirst.

L had delivered many breech babies in her life, but none of them were twins. She knew the problems a breech could cause---cord entrapment or cord prolapse in which the oxygen to the baby gets cut off, or head and shoulder entrapment in which the baby gets stuck on its way out. Most critically, she knew that in any of these scenarios, there was no option for an emergency cesarean or any of the other life saving measures for baby or mother in Zangskar. The nearest hospital was a 22 hour drive over a high pass that was still blocked by several feet of snow.

L thought of her mother, who had died almost 33 years earlier, after delivering her ninth child, a few years after N's birth. L, only six at the time, recalled the palpable fear in the kitchen as the two most prominent Tibetan doctors in all of Zangskar appeared at their door that night, one after the other. Although the second doctor performed best while inebriated and the first was more familiar with astrology and the texts of Tibetan medicine, neither had been able to do much to prevent her mother from bleeding to death after she expelled a lifeless infant.

L finished her internal exam, smiled, and told her sister that she would soon deliver. Almost in tears, she returned to the kitchen where her stepmother was churning the butter tea. She took the wooden tea churn and sent her stepmother off to call one of Karsha's more skilled birth attendant, a local pharmacist.

The pharmacist arrived perplexed, for he knew that L had delivered many babies in her career. After he performed an internal exam at L's suggestion, he went into the hallway and said "kam log", which mean vomit, the Zangskari equivalent of "oh shit". He and L resolved to labor strategy in Urdu rather than Zangskari so that N never suspected how difficult this delivery might be, nor that she was having twins. While L rubbed her sister's back and made sure that she stayed warm, she also knew to keep her ‘hands off the breech’. It was not long before N pushed out the first twin, a boy who came feetfirst. Although Zangskaris prefer a man to cut the umbilical cord, when L yielded the scissors nobody objected. While L knew to put the baby to N's breast to keep the oxytocin---biology's natural pain medication---flowing, N caught her breath and recovered some strength. A twin girl arrived shortly afterwards, slipping easily past a cervix already widened by her brother. L reached down to catch the second baby, cut the cord, wiped the baby dry and handed him to her mother who cried in relief.

Both of these stories are about “skilled attendance at delivery”, something the WHO measures and counts across the globe. This quantification has brought funding and a measure of attention to the problem of women dying in childbirth. Yet ethnography can provide an equally powerful way of suggesting what ‘skilled delivery’ or ‘humanized birth’ might mean. N and my delivery shared several critical features including the skilled management of twins and breech positioning. Yet they differ in one key regard; I had far choices more choices than N and most of the women in Zangskar. In India this year, roughly 16 million women will deliver at home and roughly 13 million will lack access to skilled attendance at birth. They deserve more, and ethnography may have a critical role to play.

For Dr. Padma

Dr. Padma (back left), Kim Gutschow (back right), and the chowkidar or night watchman at Leh Hospital.


Picture this. The Sonam Norbu Hospital in Leh, Ladakh is one of only two hospitals that serve an area the size of Norway. This area is only home to 250,000 people, making it one of the least populated regions in India, with one of the lowest fertility rates in the nation.

Why so few people? Did I mention the forbidding desert landscape at 12,000 feet above sea level--- some of the lowest precipitation in India? Or the fact that many crops don't or can't grow that high or in such a dry climate? So why all this talk about altitude?

Imagine a hospital where electricity is imminent at times and the back-up generator takes 10 minutes to kick in, depending on how cold it is and whether they guy who is supposed to start it feels like getting out of bed in the middle of the night. Imagine doing a cesarean section by flashlight, as I have heard done in Leh.

Imagine having to beg the anesthesiologist repeatedly to come in just one more night, one more time, for one more emergency obstetric complication, and he is twice your age, and is better friends with your parents than you in a very small town.

Imagine a delivery room where the heating is spotty, the mother lies down on a cold rubber surface that was scrubbed by ice cold water that may or may not have been hauled there in a bucket when the pipes freeze.

And now imagine Dr. Padma, doing her morning rounds, after she has walked the 100 yards from her tiny one bedroom apartment that is in the staff quarters next to the hospital. Always cheerful, always professional, even in the coldest weather, or in the worst mood. She is happy to discuss each patients' progress, give the nurses their instructions one more time, clarify the meds that should and should not be administered, order another ultrasound, and then discuss the latest literature on corticosteroids with me.

She graduated from one of Delhi's most prestigious medical colleges and then left a fellowship at one of New Delhi's finest public hospitals---Safdarjung--- three years ago to return home, to Ladakh, to work at Leh's government hospital. She has never accepted payment under the table for her services as many do in India's public hospitals where the salaries are almost as poor as the infrastructure.

And tomorrow she goes back down to Delhi for another shorter fellowship. Let's hope she returns.

We need more doctors like her in Ladakh. And everywhere in rural India for that matter.

AMA and ACOG fight home births

Have you heard the news?? According to ABC news (7/11/2008), the American Medical Association (AMA) recently agreed to support proposed legislation that could make having a planned home birth difficult if not impossible.

The AMA agreed to back resolution 205, in which it agreed with a recent ACOG (American College of Obstetricians and Gynecologists) position that home births are not as safe as hospital births. Both the AMA resolution and the ACOG statement on home births (2/6/2008) have come in response to the publicity surrounding the new film, the Business of Being Born. The fact that ACOG feels threatened by the film's open advocacy of home births---when home births only account for under 1% of all births nationwide in the US (the official figure, actual figures may be closer to 2%)----suggests how paranoid ACOG has become of midwives and their support of home births.

Like many of ACOG's practice guidelines or seemingly innocuous educational reports, their "statement on home births" is a highly politicized document, which bears little relationship with evidence-based medicine. Their attack on Lake and Epstein's film is hardly disguised when they say, "childbirth decisions should not be dictated or influenced by what's fashionable, trendy, or the latest cause celebre."

As if women are choosing home births because they are trendy.  It may be because home births are now safer than a hospital birth for the first time, given the current trends towards unecessary interventions, many of which are not evidence-based.  

ACOG might also have noted that childbirth decisions should NOT be influenced by legal issues. Indeed, the epidemic of inductions (up to 60%) and cesareans (30%) within low risk hospital births in the US, may be due to obstetric fears of malpractice than concern for maternal or fetal or neonatal well-being.

ACOG might have noted that childbirth decisions should NOT be influenced by economic issues. They might have noted that hospitals are trying to save money when they use electronic fetal monitoring (EFM, now used in over 90% of all hospital births in America) rather than the intermittent auscultation with a hand-held doppler still used in Europe and the developing world that offers improved neonatal and maternal outcomes over EFM in many low risk births. Click here for the NEJM article on electronic fetal pulse oximetery (which was hoped to be an improvement over EFM but the trial was cancelled when it became clear it was no improvement over a technological method already deemed questionable). Interestingly, Michael Greene's scathing rebuke of EFM in the New England Journal of Medicine (vol 355 Nov 23, 2006) that was picked up by news wires around the country during Thanksgiving week that year, is only available to NEJM subscribers, but you can see the abstract here. 
 
But they ignored the practices prevalent across the US that have contributed to a profound crisis in hospital based obstetrics that the film Business of Being Born so ably unpacks. There are no clear answers to our dilemma, but a fear mongering against the very groups that are trying to improve the birthing outcomes for women is not one.

As for the AMA decision, it is one thing to reject a phenomenon that has been studied, but quite another to reject a phenomenon they have shown almost no interest in. The most recent study of home births in its flagship journal, JAMA, dates to 1980. In other words, for 28 years nobody on the JAMA editorial board has felt the need to address the evidence on home births. Perhaps it is too difficult to study home births or there simply aren't studies out there worth reviewing? Actually there are great studies, but from Canadian or European journals, which DO show an interest in the evidence comparing home and hospital births. One of the more recent and largest studies---from the British Medical Journal (18 June 2005)---found far lower rates of intervention for home births, but comparable intrapartum and neonatal mortality rates (1.7 per 1000) than the average low-risk hospital birth.

Yeshe, small and thin


Appropos the low birthweight study I discussed in my previous post, our third child, Yeshe, who was born on Dec 30th, 2007, was low birthweight. She was born full term, at home, after a calm, smooth labor. So calm in fact that she was born with her sac intact, what is traditionally referred to as in the caul. Midwives have told me this is a sign of wisdom, psychic insight, and even spiritual teachings, while another friend set me a clipping from an early 20th century memoir that talked about how ship captains would take a caul with them to the sea for good luck. I hope this gift serves Yeshe, which means wisdom in Tibetan, well.

Will Yeshe experience any sequelae of her low birthweight? And how did she come to be low birthweight? I ate like a horse during my pregnancy and gained 35 pounds. Her weight---5 lb, 10 oz---is a mystery as is so much in life.

The question I recently debated was---when should I tell Yeshe that she was low birthweight? Or would I pathologize her by showing this concern? Sure, she'd get her birth certificate, but unless mentioning her birthweight was relevant to an ongoing health issue, why burden her? But what about my twins---who were born at 26 weeks and are now 3.5. The same strategy could apply---unless they need to know about their prematurity because of an ongoing health issue, why bring it up?  Now

Six years later, in 2017, when my kids started asking me about the books I am writing---one of which is called Sustainable Birth and teh other a medical memoir about birth in the USA and India---we read the chapter that contains their birth story, and they asked lots of questions that I tried to answer as best as I could.   The key is to remember that my story of their NICU stay is different than their story of that stay and I tried to be helpful to them first and foremost even as I explain how their birth relates to my work, as well as my mission and passion around midwifery care... .

Small and Thin

There was an article in the New Yorker (Nov 19, 2007) that had some disturbing news. For almost 20 years, scientists have been debating the "Barker Hypothesis" which found a strong association between low birthweight and increased risk of adult diseases like coronary heart failure, hypertension, type 2 diabetes, and strokes. Although initially dismissed as heretical, these findings have been repeatedly confirmed in recent epidemiological studies. The causal mechanism behind this finding appears to be a complex dialogue between fetus and mother's body---in which the fetus or even embryo adapts itself to the nutrient levels in the maternal environment. In cases where the nutrient levels are less than ideal, the fetus adapts by slowing its growth and thereby lowering its ultimate birthweight. Ironically, such infants later find the more plentiful nutrition of the postnatal environment a stressor rather than an aid to growth. Most at a disadvantage are those children who are born with low birthweight, but gain rapidly in BMI after two years of age.

This last conclusion has serious implications for parents of low birthweight babies (two thirds of whom are premature in the US). If it is dangerous for premature babies to grow too big, too fast, after age two, shouldn't we be more interested in these kids maintaining their percentile position rather than trying to jump up into higher percentiles. Are pediatricians aware of these studies and advocating against rapid weight gains between 2-5 years of age?

What does your pediatrician say? Please let us know...

The Fracas About Resuscitation

I am going to start by a recent exchange that occurred over at the preeemie experiment. The conversation---rather impassioned but never truly disrespectful---spanned two separate posts (Nov 7 and Nov 6) and garnered more than 100 comments in a 24 hour period! I like to think it began with a comment made that my husband and I made a decision a few months ago that we would not seek resuscitation in this pregnancy prior to 26 weeks. We discussed this with the high risk OB who had delivered our twins at 26 weeks 3 years ago, and duly entered this decision into our medical records.

Thankfully, we were spared the decision, as I am now 32 weeks pregnant.

However, the issue remains a serious moral quandry that I have thought about for quite some time. I had first contemplated a DNR under 26 weeks, hypothetically, years ago, when I began reading more about prematurity. While my twins' 3 month stay in the NICU in 2004 was relatively uncomplicated and they are doing very well now, my decision had less to do with their outcome than with a profound understanding of how dicey outcomes are for all premature infants. Precisely because the decision was NOT made based on my own childrens' outcomes, I don't believe it reflects on how much I value my own children. More importantly, I do not believe that a decision not to resuscitate casts any children's lives as not meaningful. However, this seems a common assumption in the heated exchanges on this topic that I have observed.

I think it is significant that very few people post or comment about DNR orders they have made. Yet a few of us who actually made the decision or acted upon it did comment in this exchange and that to me was a real accomplishment.

I think it is extremely valuable to have these kinds of comments---especially on such a sensitive and unpopular moral issue. The true test of an open and respectful forum is one in which people feel safe commenting on these issues and possibly learning from each other. Sadly, the emotional tenor of the debate led TPE to shut down comments on her blog.

I do hope that this conversation will continue. And I also believe there are many, many equally important issues surrounding prematurity that need further discussion.

Antenatal Steroids: The research

There was a heated discussion earlier this year at Neonatal Doc which turned offensive and resulted in the blog's slow death as well as the deletion of some comments regarding antenatal steroids. Oddly, the topic of antenatal steriods--which remains under research and debate---had not been covered in the neonatology blogosphere that I know of.

Let me try and summarize the gist of the debate on antenatal steriods from a cursory reading of the literature. For at least ten years there has been considerable debate on what type of corticosteroid therapy is most effective and safe in improving neonatal outcomes. The efficacy and safety of a "single repeat dose" of antenatal steroids---generally betamethasone, administered in two, repeat 6 mg shots, 12 hours apart---is unchallenged.

As doctor Roger Newman, past president of the Society of Maternal Fetal Medicine, proudly told me in an interview a few months ago, "a single course of antenatal steriods has saved as many lives as the discover of penecllin in its era." Yet he admitted the jury is still out on several major questions, including the efficacy of antenatal steriods for twin pregnancies as well as the efficacy and safety of administering multiple doses---which have been administered to women who go into preterm labor early but do not deliver.

Because the efficacy of the steroids appears to decline after one week (although question remain), women who remain pregnant have been encouraged to have repeat doses of steriods until their ultimate delivery date. Several studies have shown that three or more courses of antenatal steroids can have significant detrimental effects on fetal growth, fetal weight and length, and most importantly head circumference. As such, debate remains about the best time to initiate steriod therapy and when best to end it, to maximize its benefits but minimize the potential harm to fetal development.

An article in the April 2007 issue of Pediatrics by C Bonnano, K Fuchs, and RJ Wapner offers caution. Effectively it shows that while a single or a "rescue" course of antenatal steroids is efficacious, these effects must be tempered against adverse effects seen for 4 or more courses of steroids (these would be given if, for instance, a woman remained pregant for several more months after first going into labor and receiving a dose of steroids at perhaps 22 weeks). Moreover, further evidence about the 24 month neurological and developmental outcomes for infants treated with repeat doses of antenatal steriods is still lacking.

A recent Cochrane Database article indicates that repeat doses of corticosteriods were associated with reduced risk neonatal lung disease (primarily RDS), as well as reduced birthweight and/or head circumference. They too call for caution and studies analyzing long term outcomes of infants treated with repeat doses of antenatal steriods.

It is good news that researchers are calling for caution. Perhaps they hope to avoid the recent debacle in postnatal steriod therapy for premature infants---where dexamethasone was later shown to have profoundly deleterious effects including higher rates of CP and other neurological damage.

Research contradicts the Term Breech Trial (TBT)

A study of 13,000 breech and headfirst births at a Parisian Hospital resulted in a surprisingly high rate of vaginal breech delivery (79%). This is of the highest rates recorded in the literature. The most surprising finding was the absence of significant differences in neonatal morbidity between breech and vertex babies regardless of mode of delivery.

Additionally, there were no significant differences in neonatal morbidity between breech babies delivered vaginally and those delivered by planned cesarean. The use of strict obstetric protocols for breech presentation---including pelvimetry, continuous cervical dilation, very limited use of oxytocin or induction, and specific extraction techniques were held responsible for the excellent neonatal outcomes.

Among both headfirst and breech babies, those delivered by planned cesarean were MORE likely to be intubated than those delivered vaginally. Vertex babies delivered by cesarean were eight times more likely to be intubated and six times more likely to be admitted to the NICU than those born vaginally. See Pubmed Abstract.

These latter findings confirm recent studies showing the link between cesarean delivery and increased risk for respiratory distress syndrome in near term infants.  
A 2006 study looking at over 8,000 breech births in France and Belgium concluded that there were no significant differences between planned vaginal and planned cesarean deliveries. The study used similar outcome measures as the TBT, but far stricter criteria for obstetric management. Thus, the outcomes for vaginal deliveries far surpassed those of the TBT and several similar studies. This study showed vaginal breech delivery to be as safe as cesarean delivery, as long as careful selection criteria are followed. The TBT, by contrast, did far less to ensure the safety of the vaginal deliveries it interrogated.

Unlike the TBT, all babies in the vaginal arm were in frank breech position, with no hyper-extension (the star-gazing position). There were no infants with excessively high or low birthweights and all were subjected to continuous electronic fetal heart-rate monitoring. Moreover, pelvimetry was used for over 80% of the candidates in this study, unlike the TBT where only 10% of all women received any pelvic measurement. In this study, roughly 75% of all breech babies were delivered by cesarean. Pubmed Abstract here.

A study of over 600 births in Ireland concluded that vaginal delivery is as safe as cesarean, as long as strict protocol were followed including: appropriate fetal weight (between 2500 -3800 gms), sufficient amniotic fluid, normal fetal morphology, absence of hyperextension of the head, and absence of complete or frank breech presentation. There was no induction nor augmentation of labor other than amniotomy, and women were supposed to dilate 1 cm per hour and limited to no more than one hour of pushing. All women were attended by an experienced obstetrician, using Løvset's maneuver to deliver shoulders and the Mariceau-Smellie-Veit maneuver, if required. The authors state that both obstetric protocols and the avoidance of oxytocin for induction/augmentation are responsible for the favorable outcomes. Pubmed Abstract here.

Recent Studies in Support of the TBT

Several well-designed research trials have confirmed and improved upon the findings of the TBT, using better obstetric protocols and management. They are:

A 2005 study of nearly a million births in Sweden found higher rates of mortality among breech babies versus headfirst babies, as well as higher rates among breech babies delivered vaginally than those delivered by cesarean. Essentially, planned cesareans reduced the risk of mortality by half. Yet the study did admit that one third of all the deaths may have been independent of the mode of delivery, due to high prevalence of malformations. While the results were not strong enough to recommend that all twins be delivered by cesarean, nearly 90% of all singleton term breech babies already are sectioned in Sweden. Here is the Pubmed Abstract.

A 2005 study of term breech babies from the Netherlands confirms a dramatic rise in the cesarean rate and accompanying decline in perinatal mortality and birth trauma. Looking at more than 33,000 breech infants, the study noted a twofold decrease in perinatal death and a fourfold decrease in neonatal trauma in the two years following implementation of the Term Breech Trial. Within two months of the trial's publication, the cesarean rate for term breeches shot up from 50% to 80%, where it has remained since. Here is the Pubmed Abstract.

A retrospective study from California looked at over 100 ,000 term breech babies born over a decade. It concluded that full-term singleton breech babies delivered vaginally had much higher rates of mortality and morbidity than babies those delivered by planned cesarean. However, more than 95% of the breech babies were delivered by cesarean, suggesting a very low threshold of tolerance (or skill?) for vaginal delivery. Here is the

Critiques of the Term Breech Trial (TBT)

Marek Glazerman published a scathing critique of the TBT in ACOG 's flagship journal, American Journal of Obstetrics & Gynecology . Here is the Pubmed Abstract. The argument notes:
  • Most cases (8 out of 13 in the vaginal delivery group) of perinatal mortality were unrelated to the mode of delivery.
  • Nearly half of all perinatal deaths arose from infants who should not even have been in the study---ie. undiagnosed twins, anenchephaly, & stillbirths.
  • There were far more fetuses with birthweights over 4000 gms in the group intended for vaginal delivery than in the planned cesarean group. Again, all of these fetuses should have been excluded from the study.
  • The standard of care at two thirds of participating hospitals was so low as to put vaginal deliveries at a definite disadvantage---no facilities for immediate resuscitation, bag/mask, or immediate intubation of newborns.
  • Roughly one third of all infants with significant morbidity failed to have an experienced obstetrician in attendance.
  • In a two- year followup, study authors themselves found no differences in neurological or developmental outcomes between planned cesarean and planned vaginal deliveries. In fact, infants from the cesarean group had slightly worse outcomes than those from the vaginal delivery group.
  • This last point effectively negates the trial's major findings. Rather audaciously, Glazerman suggests that the Trial Recommendations be withdrawn. Yet even if this were to happen, he thinks it is too late to rescue the rapidly dwindling option of vaginal breech delivery. Indeed, the Trial has has been overwhelmingly adopted in most of the developed and developing world.
MJ Turner discusses the further flaws of the TBT in the Journal of Obstetrics and Gynaecology (Aug 2006):
  • The findings may apply largely to primigravidas or women giving birth the first time. There were twice as many perinatal deaths among primigravidas as among multigravidas.
  • The slight differences in immediate perinatal outcomes were not related to delivery, but to labor, especially augmented or induced labor. The adverse effects of synthetic oxytocin and other uterine stimulants on breech deliveries is well known, but was not adressed in the study's conclusions. Even more disconcertingly, the study abandoned a pre-trial consensus to use oxytocin sparingly, if at all.
  • Turner concludes that the trial's findings should be reconsidered, although he,too, agrees it is probably too late.
In an early critique published in Birth (March 2002), Marc Keirse claimed hat study guidelines doomed vaginal delivery from the start. Why so?
  • A large majority (87%) of births without an obstetrician were in the planned vaginal group.
  • The study included 2 stillbirths, two cases of twins, and two with lethal malformations---many of which died, but none of whom should have been included in the trial.
  • One third of the babies who died were low birthweight babies---whose death may have had litttle to do with mode of delivery.
  • Finally, those countries with higher rate of successful vaginal deliveries had lower rates of overall morbidity and mortality. This implies that a familiarity with vaginal deliveries may be crucial for the ultimate outcomes of those deliveries. As intuitive but often overlooked point that is the focus of Kotaska's brilliant critique.
Andrew Kotaska expresses deep reservations about the TBT and randomized control trials more generally in the British Medical Journal (2004; vol 329):
  • The study achieved a remarkable 57% successful vaginal delivery rate only by asking those centers with lower vaginal birth rates to withdraw from the trial or increase their rate.
  • As a result, centers may have increased vaginal delivery far beyond their ordinary comfort or skill level, thereby reducing the success of vaginal delivery outcomes.
  • More disturbingly, they unwittingly compromised the safety of infants and mothers in the trial.
  • The delivery as well as selection of breech babies for a safe vaginal delivery requires considerable skill and finesse---not randomization, which may take the choice out of the physicians hands.
  • The questionable results of one randomized trial are now dictating a new standard of care worldwide. This does little justice to the complex variables that influence the safety of a vaginal breech delivery.
