Vasopressin Deficiency in Hemorrhagic Shock

2014-08-27 03:14:27 | BioPortfolio


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.

Effects of Serial Phlebotomy on Vascular Endothelial Function: Results of a Prospective Double-Blind Randomized Study.

Blood donation has been proposed as a potential therapy to reduce risk of cardiovascular disease, but the effects of phlebotomy on vascular function in human subjects have not been well characterized.

Medical and Biotech [MESH] Definitions

Histiocytic, inflammatory response to a foreign body. It consists of modified macrophages with multinucleated giant cells, in this case foreign-body giant cells (GIANT CELLS, FOREIGN-BODY), usually surrounded by lymphocytes.

The body's defense mechanism against foreign organisms or substances and deviant native cells. It includes the humoral immune response and the cell-mediated response and consists of a complex of interrelated cellular, molecular, and genetic components.

Physical insults or injuries occurring simultaneously in several parts of the body.

A systemic inflammatory response to a variety of clinical insults, characterized by two or more of the following conditions: (1) fever >38 degrees C or HYPOTHERMIA <36 degrees C; (2) TACHYCARDIA >90 beat/minute; (3) tachypnea >24 breaths/minute; (4) LEUKOCYTOSIS >12,000 cells/cubic mm or 10% immature forms. While usually related to infection, SIRS can also be associated with noninfectious insults such as TRAUMA; BURNS; or PANCREATITIS. If infection is involved, a patient with SIRS is said to have SEPSIS.

The techniques used to draw blood from a vein for diagnostic purposes or for treatment of certain blood disorders such as erythrocytosis, hemochromatosis, polycythemia vera, and porphyria cutanea tarda.
