AbstractA retrospective study was performed to compare the hemodynamic effect and postoperative pain relief of fentanyl (Group F, n = 11) and buprenorphine (Group B, n = 11) in total intravenous anesthesia (TIVA) using propofol during spinal surgery. All patients were premedicated with midazolam (3-5 mg) i.m. Anesthesia was maintained with propofol infusion, and increments of fentanyl or single dose of buprenorphine with 40% oxygen in air. Total doses of fentanyl and buprenorphine were 7.6 +/- 1.0 micrograms.kg-1 and 2.0 +/- 0.4 micrograms.kg-1, respectively. Maintenance doses of propofol (Group F: 5.5 +/- 0.8 mg.kg-1.h-1, Group B: 5.9 +/- 1.1 mg.kg-1.h-1) and vecuronium were not significantly different. Mean arterial pressures from 2 hours after incision to the end of surgery were elevated significantly in Group F than in Group B. Recovery time (Group F 12.5 +/- 6.1 min vs Group B 11.8 +/- 6.1 min) and extubation time (Group F 19.5 +/- 10.3 min vs Group B 15.0 +/- 7.0 min) were not different. At the end of anesthesia, seven patients in Group F and one patient in Group B (P < 0.01) complained of severe pain. All patients in Group F, and only two in Group B (P < 0.02) received analgesics within 20 hours. Neither nausea nor respiratory depression was found in both groups. This study suggests that buprenorphine would provide a more stable hemodynamic state and better postoperative pain relief than fentanyl in TIVA using propofol.
