BACKGROUND AND OBJECTIVES: The interscalene brachial plexus block (ISB), a potent option to control @entity158 after shoulder surgery, has notable adverse effects. The anterior @entity616 ( @entity616 ) might provide comparable @entity1337 and cause less @entity73 . These characteristics were studied in this randomized controlled @entity1 - and assessor-blinded trial. METHODS: Outpatients were randomized to single-shot ultrasound-guided @entity616 (10 mL @entity1342 1%) or ISB (20 mL @entity1342 0.75%) before general anesthesia for arthroscopic shoulder surgery. @entity158 (Numerical Rating Scale, 0-10), grip strength, degree of satisfaction, and strength of recommendation were assessed. RESULTS: We randomized 168 @entity1 to each group and analyzed 164 in the @entity616 group and 165 in the ISB group. Nerve blocks were successful in 98% of the @entity1 from each group. Both procedures provided good postoperative @entity1337 , and the mean @entity158 level for @entity616 was slightly but significantly lower by 0.32 units (95% confidence interval, 0.18-0.46; P < 0.001) and noninferior given a margin of 1.1 units; P < 0.001. Within the first 24 hours, 162 (99%) of @entity616 @entity1 had unimpaired grip strength compared to 81 (49%) of ISB @entity1 (P < 0.001). The multiple primary outcome, superior unimpaired grip strength, and @entity158 control was significant; P < 0.001. Compared to ISB @entity1 (n = 130 [79%]), significantly more @entity616 @entity1 (n = 150 [91%]) were satisfied/highly satisfied. @entity1 in the @entity616 group were more likely to recommend the procedure highly. CONCLUSIONS: For outpatients undergoing arthroscopic shoulder surgery under general anesthesia, the @entity616 seems preferable to ISB. It provides excellent postoperative @entity1337 without exposing @entity1 to @entity73 and to risks of the more potent but also more invasive ISB.
