Method: In this study, a modification of the Vauzelle method of wake up test was employed. A relatively new analgesic drug, nalbuphine Hydrochloride, was used in a balanced anesthetic technique, in searching for a better methid of anesthesia that will allow awakening and spinal cord monitoring during surgey. Results: All patients were sucessfully awakened and were able to move their feet on command in 2 to 5 minutes (mean = 3.3 min. ) after the surgeon requested for the test. All patients were breathing spontaneously after the muscle relaxant was partially reversed. None required naloxone for the procedure. No complications related to the test were noted, such as self- extubation nor excessive struggling that may jeopardize the rod fixation. There were no neurological complications in this series. Conclusion: The result of our study in 5 patients indicate that balanced anesthesia with nalbuphine hydrochloride can be recommended for intraoperative awakening to monitor spinal cord function during surgery. The rapid return of wakefulness effective analgesia, reduced blood loss, stable cardiovascular system and minimal respiratory depression, make it one of the anesthetics of choice for the special procedure.
