BackgroundPrehospital transfusion capabilities vary widely in the United States. Here we describe a case of prehospital resuscitation using warmed, whole blood in a patient with penetrating torso trauma and associated hemorrhagic shock.Case ReportA 68-year-old man sustained a single gunshot wound to the left chest and was found to have a shock index of 1.5 at the time of emergency medical services (EMS) arrival. Rapid peripheral intravenous and central venous access enabled the infusion of warmed low-titer O-positive whole blood. The EMS crew intentionally resuscitated the patient before managing the airway by means of rapid sequence intubation. An air medical services helicopter crew assumed patient care from the ground EMS crew and continued the warmed, whole blood transfusion during the flight to a regional Level I trauma center. The patient went directly to the operating room from the helipad, underwent definitive operative management, and was ultimately discharged home on hospital day nine.ConclusionEarly recognition of hemorrhagic shock, implementation of prehospital transfusion protocols that emphasize transfusion of warmed blood without interruption, and an organized, regional approach to trauma care are critical for improving patient survival.
