Background In this study, the effect of naloxone on duration supraclavicular brachial plexus block was evaluated. It hypothesized that can increase neural blockade. Methods Sixty‐eight patients scheduled for surgery under were randomly assigned to receive 30 ml bupivacaine (Group C); with 100 μg fentanyl F); ng N); or and N + F). Sensory motor blockade recorded at 5, 15, min following block, every 10 end surgery. Duration sensory considered be time interval between complete first postoperative pain recovery functions. Results onset times same in all groups. The Group C (11.3 ± 1.7 h 4.56 1.0 h) F (12.8 3.3 5.1 2.0 less than other groups (18.1 2.2 6.18 N, 15.8 2.9 6.53 1.1 F, P < 0.0001). Conclusion Addition prolonged
