The Primary Endpoint of This Study Will be Day 30 Mortality. [ Time Frame: 30 days ] [ Designated as safety issue: No ]
Our primary objective, therefore, is straightforward: to develop new resuscitation regimens that are beneficial in limiting organ dysfunction and mortality after severe injury

Secondary Objective is to Better Understand the Efficacy of Novel Endpoints of Resuscitation in the Management of Shock and the Ability of These Monitors to Predict Outcome After Trauma. [ Time Frame: 28 days ] [ Designated as safety issue: No ]
secondary objective is to better understand the efficacy of novel endpoints of resuscitation in the management of shock and the ability of these monitors to predict outcome after trauma.

Low Dose Vasopressin in Traumatic Shock
Prospective, Randomized, Double-Blind, Multi-Center Trial of Low Dose Vasopressin Versus Placebo in Traumatic Shock Resuscitation

Hypothesis: We hypothesize that resuscitation regimens which minimize the total volume of resuscitation fluid, while restoring organ perfusion, will lead to lower morbidity and mortality in critically ill patients following trauma.
