Intramuscular vasopressin: A feasible intervention for prehospital hemodynamic stabilization in porcine hemorrhagic shock and whole blood transfusion

IM AVP, combined with whole blood transfusion, transiently stabilized hemodynamics by increasing systemic vascular resistance index, systolic blood pressure, and CI without respiratory compromise. These findings suggest that IM AVP may be a viable intervention for prehospital resuscitation of severe hemorrhagic shock, offering vital short-term stabilization to facilitate transport to definitive care.
