Science & Sensibility is a research blog from Lamaze International. Understanding “evidence-based maternity care” requires a certain proficiency in sorting out the good studies from the bad. Scientific evidence can help us clarify best practices, but much of the available evidence is limited, flawed, or even biased. Science & Sensibility exists to spread the word about new important studies and to help maternity care reform advocates hone their ability to critically analyze research. With a better understanding of the research, we can improve the health and care of women and infants in pregnancy, birth and beyond.

Does Progesterone Treatment Prevent Preterm Birth? A Case of “Skim Milk Masquerades as Cream”

by Henci Goer in Science & Sensibility

This is off my usual beat, but a relative asked me to investigate progesterone treatment to prevent preterm birth. In her first pregnancy, membranes ruptured at 31 weeks and the baby was born a week later. (The baby was fine thanks to her mother taking good care of herself in pregnancy, steroids to mature her [...]... Read more »

Baby it hurts: birth practices and postpartum pain

by Amy Romano in Science & Sensibility

Ask a bunch of expectant women what worries them about labor, and chances are many of them will say, “the pain.”  Much is made about pain in labor. Women prepare for it, nurses constantly assess it, anesthesiology departments exist to eliminate it, and so on. But while there are many experiences of labor pain, just [...]... Read more »

Do We Need a Cochrane Review to Tell Us That Women Should Move in Labor?

by Amy Romano in Science & Sensibility

I am reposting this post from the archives in anticipation of this week’s Healthy Birth Blog Carnival about movement in labor. It was one of the first posts I ever wrote, back before anyone was reading this blog. It’s also one of my personal favorites.
Earlier this year, media outlets shared the news of a new [...]... Read more »

No Difference? The case of cesarean surgery and postpartum infection

by Amy Romano in Science & Sensibility

When a study compares one practice with another and reports “no difference” in outcomes, is that the end of the story? Not necessarily. “No significant difference” can mean any of these:

there really is no difference
the study was too small to find the difference that really is there (it lacked “statistical power”)
the outcome was measured or [...]... Read more »

The New GBS Cochrane Review: A Hot Mess!

by Amy Romano in Science & Sensibility

Advocates for evidence based care feel our ears perk up when we hear about a new Cochrane systematic review. Cochrane Review = Evidence! Right? Indeed, systematic reviews represent the top of the “evidence pyramid” and Cochrane systematic reviews are the gold standard for their rigor and transparency. A Cochrane review can even conclusively settle important [...]... Read more »
