Vasopressin Supplementation during the Resuscitation of Hemorrhagic Shock
Principal Investigator: Carrie Sims, MD, MS

Trauma remains the leading cause of death for those under the age of forty in the United States, with a large percentage of patients dying from hemorrhagic shock within the initial hours after a severe injury. Although aggressive treatment with intravenous fluids and blood products has been the gold standard, massive resuscitation alters the neuroendocrine milieu needed to maintain vasomotor tone and is associated with the development of a vasopressin deficiency. Vasopressin is a critical hormone needed for blood pressure support during shock, and low levels are associated with recalcitrant hypotension, increased transfusion requirements, and additional morbidity.
The goal of this research was to develop targeted interventions to address hemorrhagic shock. The pilot study (Vasopressin Supplementation during the Resuscitation of Hemorrhagic Shock – the AVERT Shock Trial) evaluated the clinical applicability of using the biomarker copeptin for predicting the need for resuscitation and to monitor vasopressin deficiency. Identifying and targeting neuroendocrine deficiencies during the resuscitation of trauma patients was a novel approach to ameliorate hypotension seen in late stage shock; limiting the need for aggressive volume and blood product resuscitation and decreasing the incidence of resuscitation associated complications.
