Comparison between supra-scapular nerve block combined with axillary nerve block and interscalene brachial plexus block for postoperative analgesia following shoulder arthroscopy

Abstract

Background & objective: Inter-scalene brachial plexus block (ISB) is the gold standard for postoperative pain management in shoulder surgery. Although, this method has its side-effects and possibly complications. Suprascapular nerve block and axillary nerve block have also been used in upper limb procedures. We compared ISB with the blockade of supra-scapular and axillary nerves (called shoulder block) for postoperative analgesia after shoulder arthroscopic surgical operation under ultrasound guidance (USG) and nerve stimulators. Methodology: It was a prospective, randomized, comparative study. Results: The VAS pain scores at different times postoperatively were not significantly different between the ISB and ShB groups (P = t 0.071, 0.28, 0.378, 0.358, 0.451 at 2, 4, 8, 16, and 24 h respectively. VAS 0 was significantly difference (P = 0.029) but still the VAS score was less than 3, so no pain killers were given. Conclusion: Ultrasound guided supra-scapular and axillary nerve blocks ae equally effective as inter-scalene brachial plexus block for postoperative analgesia in shoulder arthroscopic surgery with less side-effects.
