There is a version of this case that lives entirely in the obstetric literature — a sentinel bleed, a delayed diagnosis, a OR that was thirty minutes too far away. This is not that version. This is the version where the critical care transport team is the hospital, and everything that happens between pickup and arrival is the resuscitation.
A new case report in Air Medical Journal from the University of Maryland group describes exactly this scenario: catastrophic hemorrhage from uterine rupture in a patient presenting in extremis, simultaneously hypotensive and hypoxemic, handed to a retrieval team that had to manage massive transfusion, ventilator adjustments, and the conceptual question of whether resuscitative endovascular balloon occlusion of the aorta (REBOA) was even a tool in the box.
The clinical picture
Uterine rupture is rare — roughly 1 in 1,500 deliveries — but when it happens, it moves fast. The patient described here was profoundly hypovolemic and hypoxemic simultaneously: two problems that are physiologically at war with each other. Fix the hemorrhage aggressively and you risk fluid overload in lungs already under strain. Protect the oxygenation too conservatively and you're tolerating a perfusion deficit that's worsening hemorrhagic shock.
The retrieval team leaned into damage control resuscitation — prioritizing blood products over crystalloid, accepting permissive hypotension, and adjusting ventilator settings iteratively as the patient's status evolved en route. The case specifically flags transfusion-associated circulatory overload (TACO) as a complication of ongoing resuscitation: a reminder that aggressive volume therapy carries its own hazards, particularly in a patient whose pulmonary reserve was already compromised.
The REBOA question
The authors note REBOA was considered. It wasn't deployed — and the case report doesn't spell out exactly why — but the fact that the team was running through the decision tree in real time, in a transport environment, is the detail worth sitting with.
REBOA in the prehospital and transport setting is still finding its evidence base. It offers aortic occlusion without the physiologic insult of resuscitative thoracotomy, but it requires vascular access, fluoroscopic or landmark-based positioning, and a provider comfortable with the procedure under austere conditions. For OB hemorrhage specifically, Zone III placement (infrarenal) is the relevant consideration — occlusion above the uterine vessels without jeopardizing perfusion to the thoracic aorta's territory.
The honest answer is that in most transport environments, REBOA sits at the edge of feasibility. That the team considered it at all reflects the level of clinical sophistication this kind of retrieval demands.
Where this lives in The Continuum
This case is prehospital care in the clinical sense of the word — pre-definitive surgical control, pre-ICU stabilization, pre-everything except the interventions a trained transport team can bring to bear. But it's also a case that required ICU-level ventilator thinking, anesthesia-adjacent fluid strategy, and a working mental model of endovascular hemorrhage control.
That's The Continuum. The handoff isn't a moment — it's a phase, and the team managing it has to carry knowledge from every station on the line.
The takeaway
Damage control resuscitation principles translate directly to the transport environment. Blood products over crystalloid. Permissive hypotension until surgical control. Watch for TACO — especially in patients with concurrent respiratory compromise. Know what REBOA is, where it applies, and when transport time and team capability make it realistic versus aspirational.
And when the OB emergency happens in the air, the retrieval is the resuscitation. There is no backup plan on approach.
