There's a very strong podcast series about the common failure of Epidurals: "The retrievals" season 2, by serial productions. I found it rather eye-opening. The series includes reporting on a conference of the Society for Obstetric Anesthesia and Perinatology (SOAP) where the professionals in this field also found it eye opening. (mostly episode 2)
I don't bring this up to say that actually Epidurals suck, just to bring attention to the fact that they can fail, and that the system has historically handled such failure really poorly, and that the system itself isn't very well aware of this issue. This isn't just opinion from some podcast, but also admitted by the professionals working within this field.
It's also something valuable to be aware of when you or your partner is planning to have an epidural, because there is real space (and even a need) for advocacy for the patient when an epidural fails and the woman giving birth is in excruciating pain.
I was shocked to discover that if a woman gets an epidural, it stops producing oxytocin that mitigates the pain for the baby (and mom).
That sounds absolutely horrible for that little creature. Yet I am a man, so I really am not allowed to speak on the matter and I absolutely let my wife decide entirely on the matter by herself (we had absolutely no time for an epidural, my wife delivered both kids way too fast)
The problem that The Retrievals deals with is epidurals failing during cesarians, which, they're quick to emphasize, is painful, open abdominal surgery. The not-so-simple solution is to convert to general anesthesia (anesthetic gas, IV propofol, etc). This isn't without its risks to the mother and the child, so there's reluctance on the part of anesthesiologists to go that route if there's other options. The result is unnecessary birth trauma.
