Evidence Based Birth

Frequently Asked Questions… that Other People have Already Answered!

Here at www.EvidenceBasedBirth.com and on my Facebook page, I receive many questions about the evidence for various labor and delivery practices. Unfortunately, due to my busy life as a professor and a mother of two, I don’t have time to write all the evidence-based articles that I would like. So that’s why I love to point people to evidence-based blog articles that other people have already written. Here are a few of my favorites!

Disclaimer: I agree with most, but not all, of the points listed in these articles. I probably would have written my articles in a slightly different style. But with that being said, I think these are reliable sources and that the authors cover the available research pretty thoroughly. 

Q: What is the evidence for delayed cord clamping?

A: Nicholas Fogelson (the Academic OB/GYN) has a series of articles on delayed cord clamping. You can read his original article here, a follow-up article here, and if you have time you can watch his grand rounds lecture on YouTube here. To sum it all up, delayed cord clamping has many benefits for both pre-term and term infants, although it does lead to a higher risk of jaundice. (The higher risk of jaundice is not surprising, really, since the breakdown of red blood cells contributes to jaundice, and infants who have delayed cord clamping have more red blood cells).

Q: My doctor says that my baby has to stay lower than my placenta if I want delayed cord clamping. Is this true?

A: Dr. Mark Sloan (a pediatrician) has written an article about this and other controversies related to delayed cord clamping here. The short answer? No, the baby does not have to stay below the level of the placenta while the cord is still intact; it is perfectly fine for the baby to be in your arms!

Q: Is evening primrose oil safe to use during pregnancy?

A: Jen Kamel of VBACFacts.com looked at the very little research available on evening primrose oil and summarized the evidence here. Her conclusions? There is no evidence showing that evening primrose oil (EPO) is safe during pregnancy, and there may be potential harms.

Q: What is the evidence for letting the placenta come out on its own time versus giving Pitocin and putting traction on the cord?

A: Midwife Thinking wrote an interesting article about the evidence on this topic here, explaining why the evidence suggests that “active management” (giving Pitocin and putting traction on the cord) may be more beneficial for most women who give birth in hospital settings. (To understand why I highlighted those two words— “most” and “hospital”—read the article!). 

Q: Can you lead me to evidence-based research or randomized double-blind studies regarding placenta encapsulation?

A: As far as I can tell, no research on this subject exists!  Unfortunately, I can’t help you evaluate the research evidence if there is none to be had.

Q: I’m looking for information on epidurals. Can you help?

A: It’s not a blog article, but there is a great evidence-based resource about epidurals on Childbirth Connection’s website, which you can read here. The take-home point? Epidurals are highly effective at relieving pain but also carry many potential harms.

Q: Is suspected “big baby” a valid medical reason for an induction or C-section?

A: Jill Arnold from the Unnecesarean has written extensively about the research on this topic. You can see a list of her “big baby” articles here, or you can just check out this one (my favorite). Want the quick answer? Current evidence does not support early induction of labor for suspected big babies. Induction of labor doubles the risk of cesarean delivery without reducing the risk of shoulder dystocia or newborn morbidity. The same could be said for elective C-section for a suspected big baby—this practice is not supported by evidence.

Q: Was my Cesarean for “failure to progress” really necessary?

A: It would be inappropriate for me to listen to your story and tell you whether or not your C-section was necessary. However, research has shown that “failure to progress,” also known as labor dystocia, is a common cause of preventable C-sections. In fact, a substantial number of un-planned C-sections are due to “failure to progress,” and research shows that almost all of the time these diagnoses were made prematurely. The Well-Rounded Mama talks about how a woman’s failure to progress is frequently just the care provider’s “failure to wait”—especially when it comes to larger women.  You can read her evidence-based article here.

    Nice!

    Looks like there may be some new info on placentophagy soon. Read on PBi’s facebook; “Research update: Our paper on women’s experiences with placentophagy will FINALLY be published! Online Jan 27, printed in next edition of Ecology Food & Nutrition!”. I’m not sure if this will be just anecdotal or actual research though.

    I thought this was a pretty balanced review of the (scant) scientific evidence regarding postpartum placenta ingestion.

    I would love to see evidence about the use of TENS for pain control in labor :)

    Just found this the other day and his other articles on natural birth all with references. May be worth a look for you.

    thanks for your blog and all you do to help inform and spread the truth about birth.

    Any good sites on circumcism? I really need help in deciding if I should circumcise my son or not circumcise my son when he is born.

    • Rebecca January 12, 2013

      Hi Laura Lee, this is a great question! Circumcision is a controversial subject, and it is hard to find articles that are written in a non-biased, evidence-based manner. I think that the American Academy of Family Physicians has a pretty good summary of the benefits and harms, although it is 5 years old. http://www.aafp.org/online/en/home/clinical/clinicalrecs/guidelines/Circumcison.html. The American Academy of Pediatricians just came out with a new recommendation saying that the benefits are small, and the risks are small, but that in their opinion the benefits outweigh the risks enough that parents should have access to the procedure if they want it. However, I worry that there is enough of a conflict of interest ($$$ made off of circumcisions) to make me a little wary of the AAP’s statement. Now as far as the ethical issues related to– that is a much harder issue for me to find good, non-biased information about. Here is an article that I think presented a good, non-biased (non-inflammatory) picture of both the evidence and the ethics: http://www.circs.org/index.php/Library/Benatar2.

      Bottom line, would you alter your daughter to look like you? Is it religious reasons? Read Galations. Health? Boys have a higher chance of breast cancer than any penile cancer. And finally, his body, his choice. Its easier to remove than give back!

      ^^^^ this from a mom who cut her son :(

    what is the evidence for limiting visitors in the labor hall or on the postpartum area during flu season or recently when there was an outbreak of pertussis. Our OB unit has what I believe to be a ridiculous “temporary policy” of only allowing siblings, parents and immediate family in the labor hall and on the unit. No friends at all. Even adult friends.

    I am so glad to see this effort and have already directed friends who are child-bearing age to it. I had no access to such information for my three childbirth experiences which were fairly easy and uneventful. But, I would have loved to have known all that is available to understand now. Those three are now making their own families and already my daughter had given birth at home and very successfully is supported by this site and friends and midwife who espouse the evidence-based birth practices. Thanks for your work and please keep it up!
