【 摘 要 】

Background and objectives: The purpose of this study was to evaluate the onset, quality and duration of sensory andmotor blockade achieved with hyperbaric bupivacaine and nalbuphine combination when administered intrathecally forspinal anesthesia in lower abdominal surgery as well as efficacy of nalbuphine for postoperative analgesia and its sideeffects if any.Method: 40 ASA I and II patients of age group 50-70 years, scheduled for below umbilicus surgeries were chosen forthis study. Patients were randomised in two equal groups of 20 each by lottery method. Group I (Study Group) received3 ml of hyperbaric bupivacaine 0.5 % + 0.5 ml inj. nalbuphine (0.5 mg) intrathecally. Group II (Control Group) received3 ml of hyperbaric bupivacaine 0.5 % + 0.5 ml of inj. normal saline intrathecally. Assessment of motor and sensoryblockade was done by Bromage scale and pin prick method. Pulse rate, BP, respiratory rate and SpO2 were monitored.Results: There is no significant difference between 2 groups for onset of motor and sensory blockade but mean time ofpostoperative analgesia in Study Group was highly significant than Control Group. No patient in our study developedany side effects.Conclusion: Nalbuphine provides better quality of block as compared to bupivacaine alone. It also prolongspostoperative analgesia when used as adjuvant to spinal bupivacaine in elderly patients.
