Intraoperative high-dose dexamethasone for cardiac surgery: a randomized controlled trial.

Context: Prophylactic corticosteroids are often administered during cardiac surgery to attenuate the inflammatory response to cardiopulmonary bypass and surgical trauma; however, evidence that routine corticosteroid use can prevent major adverse events is lacking.

Objective: To quantify the effect of intraoperative high-dose dexamethasone on the incidence of major adverse events in patients undergoing cardiac surgery.

Design, Setting, And Participants: A multicenter, randomized, double-blind, placebo-controlled trial of 4494 patients aged 18 years or older undergoing cardiac surgery with cardiopulmonary bypass at 8 cardiac surgical centers in The Netherlands enrolled between April 13, 2006, and November 23, 2011.
