A comparative study between the effect of verapamil versus nalbuphine as an adjuvant in supraclavicular brachial plexus block

Abstract Background Brachial plexus block has substituted general anesthesia in the majority of patients planned for upper limb surgeries as it avoids undesired effects medications used well stress response associated with airway manipulation. Opioid agonist–antagonists such nalbuphine are adjuvant to improve anesthetic properties bupivacaine. Verapamil an additive effect brachial blockade form decreasing consumption analgesics postoperative period reducing onset time and extending duration motor sensory blockade. The aim this study is investigate verapamil versus 0.5% bupivacaine regards onset, analgesic augmentation. randomized, prospective, double-blinded, comparative where 90 subjected arm, forearm hand were randomized into three groups, group A received 30 ml plain plus 2 normal saline, B equivalent 5 mg, C 10 mg diluted saline. Results showed that was 7.25 ± 1.5 vs. 10.92 3.84 min, P < 0.001 shorter than (13.2 2.66 min). In addition, (11.10 1.24 13.50 3.77 0.001) (17.16 1.30 B, 396 32.17 355.83 18.48 0.001, respectively longer (321.13 25.08 Also, there prolonged recording (338.92 25.2 302.93 15.24 (280.70 32.35 Time demand rescue analgesia dose significantly long (449.53 52.45 418.13 41.12 (361.31 21.42 Both have improving all parameters block. Conclusion drugs produce favorable enhancement effective prolongation extend superiority over verapamil.
