Delirium Reduction by Volatile Anesthesia in Cardiac Surgery

Summary

Parallel group, prospective, randomized, controlled, single-blinded trial. The aim of our study is to test the hypothesis that volatile anesthesia would reduce the incidence of early postoperative delirium in patients undergoing cardiac surgery with CPB as compared to TIVA.
