%X Sa£¿etak Background and Purpose: Unilateral spinal anaetshesia restricts the distrubution of spinal block preferentially to the operative side. Intrathecal coadministration of opioids increases sensory block without enhancing motor or sympathetic block. In this study we compared unilateral hyperbaric bupivacaine spinal anaesthesia with or without fentanyl in patients undergoing varicose vein surgery. Material and Methods: 40 ASA I-II adults randomly received unilateral spinal anaestehsia with hyperbaric bupivacaine 7.5 mg (Group B, n=20) or hyperbaric bupivacaine 5 mg+ fentanyl 25mg (Group BF, n=20). Sensory and motor block, hemodynamic data and side-effects were recorded. Results: Maximum level of sensory block on operative leg was Th11 (Th12-Th8) in Group B and Th12 (Th12-Th10) in Group BF, P=0.09. Complete motor block had 12 (60%) Group B and 4 (20%) Group BF patients, P=0.02. Total regression of motor block required 127 ¡À 31 min in Group B and 87 ¡À 18 min in Group BF, P<0.001. Maximum decrease of systolic arterial pressure from start value was 19 ¡À 9% in Group B and 16¡À 6% in Group BF, P=0.32 and of heart rate 23 ¡À 10% and 17 ¡À 7%, P=0.06, respectively. Pruritus had 9 (45%) Group BF patients, P=0.001. Conclusion: Unilateral hyperbaric bupivacaine 5mg+fentanyl 25 mg spinal anaesthesia provides adequate intraoperative sensory block in operated leg and results in similar cardiovascular stability, less intense motor block and faster motor recovery than unilateral hyperbaric bupivacaine 7.5 mg spinal anestehesia in patients undergoing varicose vein surgery
