Prehospital hypotension is associated with worse clinical outcomes in patients who sustain traumatic injuries. Administration of vasoactive medications, including norepinephrine, is not advocated in North American trauma systems due to the belief that vasopressors will worsen clinical outcomes and increase mortality. However, in European trauma systems prehospital vasopressor administration is included as part of the guidelines for the management of hypotension and hemorrhagic shock. There are multiple physiologic explanations for why prehospital vasopressor administration may be useful in patients with traumatic shock, such as providing adequate blood pressure to maintain vital signs until arrival at the trauma center, allowing adequate organ perfusion in the setting of low blood flow, and supplementing decreased hormone production in the later stages of hemorrhagic shock. The purpose of this retrospective study is to investigate if prehospital norepinephrine administration is associated with decreased mortality in patients with traumatic shock. The investigators will collect patient data from previously collected sources of information and trauma databases from three separate locations: the TRAUMABase consortium in Paris, France; TRENAU trauma database from Grenoble, France; and the R Adams Cowley Shock Trauma Center in Baltimore, MD, USA. The investigators will perform statistical modeling to propensity score match patients that received prehospital vasopressors with patients that did not receive prehospital vasopressors and assess the association with 24-hour and 28-day mortality.
