Background: Supraclavicular brachial plexus block has evolved as a safe alternative to general anaesthesia with good postoperative analgesia. In an attempt to hasten the onset of block and increase the duration of postoperative analgesia, various adjuvant drugs are used along with local anesthetic agents.
Aim: The present study was undertaken to assess the analgesic efficacy of butorphanol (2mg) and tramadol (100 mg) as an adjuvant to levobupivacaine in supraclavicular brachial plexus block during perioperative period.
Study Design: This was a prospective, randomized, double blind study done on 100 adult patients of ASA I-III aged between 18-65 years and scheduled for various upper limb surgeries below the level of elbow.
Materials and Methodology: Patients were allocated by computer generated random draw into two groups of 50 each and were administered the study drugs under ultrasonographic guidance. Both groups received 22ml of the study drug (Group B 20 ml 0.5% levobupivacaine + Butorphanol 2mg and Group T 0.5% levobupivacaine + Tramadol 100 mg). Patients were assessed for duration of postoperative analgesia, onset & duration of sensory as well as motor blockade and occurrence of any side effects.
Results: Duration of postoperative analgesia was significantly elevated in group B (683±88.58 min), as compared to group T (483.2±45.24 min.) with p<0.001. Onset of sensory and motor blockade was comparable among both groups (p>0.05). Duration of sensory and motor block in group B was significantly longer compared to group T (p<0.001). Hemodynamics were stable and side effects were minimal in both the groups.
Conclusion: Butorphanol 2mg when added to 20ml 0.5% levobupivacaine in brachial plexus block, significantly prolongs the duration of postoperative analgesia, sensory and motor block as compared to addition of 100 mg tramadol, with minimal side effects and hemodynamic changes. However, these adjuvants shorten the onset times of sensory and motor block to a similar extent.

Abstract

Background: Axillary brachial plexus block is generally regarded as the safest and reliable technique for forearm and hand surgeries. Dexmedetomidine, a potent alpha (α)-2-adrenergic receptor agonist when used as an additive in any peripheral nerve block can improve quality of block and postoperative analgesia, though uncertainity prevails regarding the dose in patients undergoing hand and forearm surgeries.
Methods: In this prospective, randomized, comparative, double blind study, 80 patients were included. Each participant fulfilling the inclusion criteria then received axillary brachial plexus block using 15cc 2% lignocaine with adrenaline (1:200000)and 0.5% bupivacaine 5cc mixed with dexmedetomidine either 0.5 µg /kg (group A) or 1 µg /kg ( group B)in 2cc normal saline. Duration of post-operative analgesia was the primary outcome.
Result: Duration of analgesia was significantly prolonged in group B (493.77±115.62 min) compared to group A (434.62±45.18 min, P <0.01).
Conclusion: Between the two doses of dexmedetomidine, block characteristics and analgesia obtained were better with higher dose (1 µg/kg) but chances of side effects like bradycardia increased. Hence 0.5 µg/kg can be a better dose with improved block characteristics yet negligible side effects.
