Effect of Etomidate on Hemodynamics and Adrenocortical Function After Cardiac Surgery

March 3, 2010 updated by: University Hospital Inselspital, Berne

Effect of an Anesthetic Induction Dose of Etomidate on Hemodynamics and Adrenocortical Function After Cardiac Surgery

The purpose of this study is to evaluate the effect of a single dose of etomidate for patients undergoing cardiac surgery with the use of cardiopulmonary bypass (CPB) on post-CPB adrenocortical responsiveness, on requirements of hemodynamic support, and on use of intensive care resources.
