Background Regional anesthesia has been widely practiced with minimal risk of complications. The aim of this study was to compare the efficacy of nalbuphine and tramadol as separate adjuvants to lidocaine in intravenous regional anesthesia (IVRA) (Bier's block). Materials and methods This randomized double-blind controlled study was conducted in the Department of Anesthesia, Kasr Al Ainy Teaching Hospital, Cairo University, Egypt. Sixty patients, aged 20-60 years, ASA I-II, both sexes, scheduled for minor hand surgeries under IVRA were enrolled in the study. The patients were randomly allocated into three equal groups: group L (n = 20) received lidocaine in IVRA, group LT (n = 20) received lidocaine and tramadol mixture, and group LN (n = 20) received lidocaine and nalbuphine mixture. The onset, duration of both sensory and motor blocks, time to first analgesic request postoperatively, and complications related to the drugs or technique were recorded. Results There was a statistically significant acceleration in the mean onsets with significant prolongation of the mean duration of sensory and motor blocks in group LT and group LN compared with group L (P < 0.05). The results observed in both groups were comparable. In addition, there was an increase in the mean time to first analgesic request in group LT and group LN compared with group L (P < 0.001). Group LN had the longest duration time of postoperative analgesia and this was statistically significant compared with group LT (P < 0.001). Complications were minimal and nonsignificant. Conclusion The use of nalbuphine and tramadol as adjuvants to lidocaine in IVRA resulted in significant acceleration of the onset and prolongation of the duration of both sensory and motor blocks, with minimal insignificant complications. Both tramadol and nalbuphine effects were comparable.
