Study ObjectiveTo compare three anesthetic strategies with respect to the time of extubation after coronary artery bypass graft (CABG) surgery and to assess patient satisfaction with the procedure.DesignProspective, randomized, clinical study.SettingTertiary-care referral center.Participants180 cardiac surgical patients undergoing primary CABG from January through June 2004.InterventionsAfter induction of general anesthesia, patients were allocated to one of three groups. All three groups received a continuous infusion of intravenous (IV) propofol perioperatively and postoperatively. Group 1 (fentanyl infusion group, n = 60) received continuous IV fentanyl infusion perioperatively and postoperatively for analgesia. Group 2 (diclofenac group, n = 60) received fentanyl bolus doses intraoperatively and diclofenac suppository postoperatively. Group 3 (remifentanil group, n = 60) received continuous infusion of IV remifentanil perioperatively and IV fentanyl as an immediate postoperative bolus followed by continuous fentanyl infusion. Duration of postoperative ventilation up to the time of extubation, inotrope requirement, time at which analgesic infusion was discontinued, postextubation arterial blood gas analysis, pain evaluation via visual analog scale, need for rescue analgesia, awareness during surgery, and length of postcardiac surgical unit stay, were evaluated in each patient.Main ResultsThe diclofenac group exhibited the shortest time to extubation, the least inotrope use, and the fewest rescue doses of analgesic than did patients of the other two groups.ConclusionIntravenous propofol with bolus doses of IV fentanyl intraoperatively in combination with postoperative nonsteroidal antiinflammatory drugs had the best recovery profile in patients undergoing primary CABG than did the other two regimens studied.
