Surgical tech here. I've done a metric fuck-ton of c-sections, and those cases can be brutal as hell. Never been in on a vaginal delivery, cuz that's not OR territory, but c-sections are the kind of case you're on high alert for the entire time cuz shit can go south really fast for both mother and baby. The amount of force I've seen (and contributed to) applied to get a baby out is definitely in dismemberment territory if there was some defect at play.
Some of the most horrific things I've seen in the OR have been in the c-section room. But they're the kind of thing that if you don't do, it's basically a death sentence for the mom or the baby.
Based on my own experience, I'd give the doc and delivery team the benefit of the doubt in terms of the operation: extreme circumstances can call for an extreme response, and when that doesn't work, the result is also extreme. This is a case that will haunt the staff involved all the way to the grave - really hope the hospital hooks them all up with top-notch therapy after that shit.
The lack of transparency after the fact though is 100% inexcusable, but also unsurprising coming from a private hospital. Their decisions are driven by money and PR. Ethics are a tie breaker at best.
