Brief summary
Vasoplegia is an important determinant for adverse postoperative outcome and is observerd in 5% to 54% of patients undergoing cardiac surgery using cardiopulmonary bypass (CPB). Postoperative vasoplegia is defined as a state with low systemic vascular resistance despite a normal or high cardiac output, and the need for vasopressor therapy. Steroids attenuate the inflammatory response to cardiopulmonary bypass,but their effect on clinical outcomes is uncertain. This is a double-blinded, randomized, clinical trial designed to determine the efficacy of low dose corticosteroid infusion in vasopressor free-days in vasoplegia after cardiac surgery.
Interventions
Steroid group will receive 200 mg of hydrocortisone diluted in 120 mL of saline at an infusion rate of 5mL/hr for 3 days or shock reversal
Control group will receive 120 mL of saline solution at a rate of 5mL/hr for 3 days or shock reversal
