Post Operative Hemodynamic Function After Anesthetic Induction With Etomidate for Cardiac Surgery With ECC

Because of its hemodynamic safety, etomidate is widely used for anaesthesia induction of cardiac surgery. It can also cause adrenal insufficiency during the following 48 hours ( 11 betahydroxylase inhibition ). So it could increase hemodynamic dysfunction caused by the SIRS following cardiopulmonary bypass. A previous observational study found more adrenal insufficiency and need for vasopressive support therapy in the etomidate group versus another propofol induced group. The aim of our work is to compare hemodynamic dysfunction following induction with etomidate for cardiac surgery with ECC. The control group would be induced by Propofol. 94 patients would be included.
