Abstract
The aim of this study was to evaluate which factors affected recovery from anesthesia in 50 postoperative patients undergoing coronary artery bypass grafting surgery (3 to 5 bypasses) Patients who had either renal or hepatic dysfunction, or any perioperative complications were excluded. Anesthetics used for the surgery included fentanyl (38 to 80μg•kg-1), midazolam, and vecuronium. Of all the factors evaluated perioperatively, either youth, better postoperative cardiac indexes, or shorter extracorporeal circulation time were associated with earlier emergence from anesthesia, However, no correlation was observed between the total dose of either fentanyl or midazolam. These data suggest that the emergence from anesthesia in patients undergoing CABG depends upon postoperative cardiac function, and surgical invasiveness, rather than the anesthetics used.
