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.

Condition Intervention
Shock, Traumatic
Drug: normal saline control
Drug: vasopressin

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Prospective, Randomized, Double-Blind, Multi-Center Trial of Low Dose Vasopressin Versus Placebo in Traumatic Shock Resuscitation

Primary Outcome Measures:
  • The Primary Endpoint of This Study Will be Day 30 Mortality. [ Time Frame: 30 days ]

Secondary Outcome Measures:
  • 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 ]
