Ultra-fast track anesthesia aims at immediate extubation of cardiac surgical patients at the end of the operation. In the current study, we compared the effect of performing ultra-fast track anesthesia versus continued postoperative mechanical ventilation on the length of ICU stay. Fifty two patients were divided into 2 groups, ultra-fast group and conventional group.There was a significant reduction in the length of ICU stay in the ultra-fast group, without increasing postoperative complications.
