Hold Up, There’s No New Study About Epidurals and Total Length of Labor

Do epidurals widen labor? Read a headlines this week and you’d consider we finally answered that doubt once and for all—with epidurals branch out to have no effect. But a investigate indeed asked what happens if we already have an epidural, and spin it off as you’re pulling out a baby.

The Headline: Epidurals Do Not Prolong Labor (New York Times)

The Story: The investigate looked during a effects of epidurals in a “second stage” of labor, and really, do any of us indeed know what a second theatre of labor unequivocally is? Obstetricians do, though we consider many of a people essay and tweeting a headlines do not.

What we consider of as “labor” is unequivocally a initial theatre of labor: when a cervix is dilating, and you’re feeling contractions, and it hurts, and you’re removing prepared to go to a hospital, and afterwards you’re during a hospital, and there are still hours to go, and oh God how will we ever get by this, ow ow ow ow.


The second theatre of labor is when you’re finally bulging to 10 centimeters and get to start pushing. It might take an hour or dual if this is your initial baby. If you’ve finished this before, pulling might usually be a matter of minutes.

(There is a third stage. It happens after a baby is born.)

So what happened in this investigate about a pushing theatre of labor? 400 women during one sanatorium in China, all giving birth for a initial time, got epidurals during a initial theatre of labor. When it was time to push, some of them kept removing a pain-killer liquid in their epidurals, while others got a salty placebo. The thought was to exam either doctors should be branch off a epidural when it’s pulling time.


In a end, a people who had a genuine epidural and a feign epidural during pulling both delivered equally fast (51 contra 52 mins of pushing, on average). On a other hand, a 2014 investigate found that epidurals do widen pushing, and their numbers were 3 contra 5 and a half hours. Big difference.

The 2014 investigate only looked during charts from women who did and didn’t get an epidural; there was no humorous business going on with a placebo. That means these dual studies are seeking totally opposite questions. The new investigate is a right approach to investigate either a pain-killer in a epidural interferes with pulling itself. The 2014 investigate includes a whole experience, including your doctor’s biases, a fact that it’s harder to pierce around when you’re tethered to an epidural machine, and a million other factors that are concerned in what actually happens when we ask an epidural.

The Takeaway: If you’re meditative about either to get an epidural, you’re substantially wondering either it’s going to widen your total time in labor, not either it’s going to trim a few mins off a pulling stage. There is justification that epidurals do boost a initial theatre (the long, differently hurty part) of labor, and this new investigate didn’t protest that. Whether epidurals widen a pulling theatre is still adult in a air.
