Do Epidurals Decrease Maternal Morbidity?

Q&A on severe maternal morbidity

Emily Oster

3 min Read

I recently saw an article that stated that epidural use could decrease severe maternal morbidity risk. They found that the use of an epidural in vaginal deliveries was associated with a decrease in the risk for severe maternal morbidity — and this was true regardless of the woman’s race. That seems really significant. What is your take on this study?

—Caren

This is a very nice study; you can see it in full here. The authors’ bottom line is that use of an epidural decreases severe maternal morbidity by 14%, mostly driven by a 9% decrease in the risk of postpartum hemorrhage. By way of background: postpartum hemorrhage is defined as a loss of more than 1,000 milliliters of blood, which can often be treated but is scary and dangerous. This complication occurs in about 2% of births; this paper therefore implies that an epidural would reduce the risk by about 0.2%, or 2 in 1,000. This effect is significant, but it is small in magnitude.

The paper is an observational study — they compare women who had epidurals with those who did not — and as you would expect, the samples are quite different. Epidurals are more common among women who give birth in teaching hospitals, for example, and those hospitals have better resources on other dimensions, too.  These differences are a concern but what is effective about their analysis, though, is that they have a huge sample: seven years of all births in New York, for a sample size of almost 600,000. This allows them to better match the women with epidurals to those who do not have them (more on this strategy here).

When they do this matching, they are able to better compare across similar women, and they find this reduction in risk for those who use an epidural. The authors appropriately caveat that they cannot be sure it’s the epidural versus other unmeasured features of the two groups. And they cannot know why this is happening, although they suggest it may be that it’s faster to intervene on some risks if women already have an epidural (because some of these interventions hurt).

Is this a reason to have an epidural if you otherwise do not want one? Perhaps not, given the small effects. But I share the view of the authors that it is a reason that epidurals should be available to everyone if they do want them. And certainly this deserves more research.

“Whilst googling things like ‘new dad sad’ and ‘why am I crying new dad,’ I came across an article written by a doctor who had trouble connecting with his second child. I read the symptoms and felt an odd sense of relief.” Today we’re bringing back an essay by Kevin Maguire of @newfatherhood about his experience with paternal postpartum depression. We need to demystify these issues in order to change things for the better. Comment “Link” for a DM to read his full essay.

What does the data say about children who look more like one parent? Do they also inherit more character traits and mannerisms from that parent? Let’s talk about it 🔎

SLEEP DATA 💤 We asked you all about your kids’ sleep—and got nearly 15,000 survey responses to better understand kids’ sleep patterns. Comment “Link” for an article that breaks down our findings!

This graph shows sleeping location by age. You’ll notice that for the first three months, most kids are in their own sleeping location in a parent’s room. Then, over the first year, this switches toward their own room. As kids age, sharing a room with a sibling becomes more common. 

Head to the newsletter for more and stay tuned for part two next week on naps! 🌙

Weekends are good for extra cups of ☕️ and listening to podcasts. I asked our team how they pod—most people said on walks or during chores. What about you?

Bug season is upon us. Besides annoyance, this can bring up safety concerns, particularly with ticks. They are carriers of diseases, most notably Lyme disease. So what’s the best course of action?

Prevention is key! I suggest:
⭐ Regular tick checks
⭐ Using bug sprays with DEET 
⭐ Wearing long sleeves and pants in the woods

Some parents worry about DEET, but repellants with up to 30% DEET are recommended by both the CDC and AAP. The data says you’re in the clear, so go for it. Enjoy your summer!

Looking for Memorial Day Weekend plans? Might be the perfect time to give potty training a shot. Potty training is notoriously difficult, and we unfortunately don’t have a lot of evidence-based guidance on what works best. So I asked the ParentData community to fill out a survey and share their knowledge — about 6,000 people responded.

Sun safety is a must for all ages, especially babies! Here are my tips for keeping your littlest ones protected in the sunshine:
☀️ Most importantly, limit their time out in hot weather. (They get hotter than you do!)
☀️ Keep them in the shade as much as possible when you’re out.
☀️ Long-sleeve but lightweight clothing is your friend, especially on the beach, where even in the shade you can get sunlight reflecting off different surfaces.
☀️ If you want to add a little sunscreen on their hands and feet? Go for it! But be mindful as baby skin tends to more prone to irritation.
