Efficacy of low dose Interscalene Brachial Plexus Block on post anesthesia recovery parameters after Shoulder Surgery

Objective: Excellent postoperative pain control plays central role in the outcome of open shoulder surgery which provides early rehabilitation and accelerates functional recuperation. Methodology: Fifty patients who were candidate for elective shoulder surgery were enrolled in this study. Patients were randomized to two 25-patient groups. One group received morphin sulfate and in the other group small volume Interscalene Brachial Plexus Block (ISBPB) was performed. Pain severity, patient satisfaction scores and post anesthesia recovery parameters were assessed. Results: Patients satisfaction score was significantly improved in ISBPB (P<0.001). Agitation in ISBPB group was significantly reduced compared to the other group (P: 0.009). Pain severity score was significantly reduced with ISBPB (P=0.001). ISBPB did not have any side effects on post anesthesia recovery parameters. Conclusion: Small volume ISBPB may be considered as a suitable technique for reducing intermediate postoperative pain without any effect on post anesthesia care unit parameters and stay in patients undergoing open shoulder surgery.
