Vasopressin Deficiency in Hemorrhagic Shock

The University of Texas Health Science Center at San Antonio81 enrolled

Overview

In this study we hope to delineate the typical vasoactive mediator response of trauma patients to shock. We plan to assess serum levels of vasopressin and also catecholamines, angiotensin, and cortisol during resuscitation of trauma patients to delineate high risk populations for vasopressin deficiency.

This is a prospective observational study. The only research-driven procedure will be the removal of blood samples at designated time points(total blood removed 48 cc per patient). Hemodynamic, fluid infusion and agitation/pain data (RAMSEY Score) will prospectively be collected for research purposes. We will collect data from a convenience sample of patients (when research staff is available) over a one year period.
