The classic framework — tone, trauma, tissue, and thrombin — is a useful starting point, and one most of us learned early on. Uterine atony is the most common culprit, but retained placental tissue, a genital tract laceration, uterine rupture or inversion, placenta accreta spectrum, and coagulopathy each call for a different response, and it's not unusual for more than one of these to be happening at once.
When I review a hemorrhage case, I'm looking at the pre-delivery risk assessment, the baseline hemoglobin, what blood-bank preparation was in place, the quantitative or estimated blood loss, the cumulative loss across delivery and recovery, how vital signs trended over time, uterine tone, the exams that were done, the medications and procedures used, lab trends, when blood products were actually transfused, and whether and when the team escalated to the OR or a higher level of care. An important point is that a stable blood pressure does not necessarily exclude significant blood loss — especially in a young, healthy patient whose body can compensate for a surprisingly long time before things suddenly look very different.
Depending on which side is reviewing, that same record can tell different stories. One reading might point to delayed recognition, a failure to actually quantify cumulative blood loss, temporizing measures repeated despite clear deterioration, slow activation of blood products, or a response to abnormal vitals that simply wasn't fast enough. Another might point to a genuinely rapid onset despite the team being appropriately prepared, a rare underlying cause, timely and sequential treatment, reasonable judgment made as conditions kept changing, or an outcome that wouldn't have changed even with prompt management.
I'll also say this: modern hemorrhage care is a team effort, not a solo one. So the analysis often has to look beyond one physician's actions — at medication access, massive transfusion protocols, staffing levels, communication between team members, transport logistics, and whether an OR was even available when it was needed. A fair review keeps that in mind. It draws a real distinction between a complication that happened despite good care and a failure that could have been prevented, and it looks honestly at both the bedside care and the system that care happened within.
Questions for Counsel
- Was quantitative blood loss measurement (QBL) being used at the time of delivery, or did the care team rely on visual estimation — and was there an institutional protocol requiring QBL?
- At what point did blood loss reach the threshold for PPH, and was there a documented clinical response at that time consistent with the hospital's hemorrhage protocol?
- Was the PPH etiology identified and was the treatment directed at the correct etiology?
- Was there a documented escalation through the uterotonic medication sequence before reaching the threshold for surgical intervention?
- Was massive transfusion protocol activated, and if so, was the timing consistent with the documented clinical deterioration?
