Interscalene brachial plexus block (ISBPB) complications depend usually on the dose administered.
The object of this study was to determine whether ultrasound-guided ISBPB with 6 ml of 0.5% levobupivacaine would reduce occurrence of respiratory depression and hemidiaphragmatic paralysis.
Patients undergoing arthroscopic shoulder surgery under nerve block with general anesthesia (n = 20) were recruited. There were no differences between pre and post operative respiratory function (forced expiratory volume 1.0 (sec) % and vital capacity). Hemidiaphragmatic paralysis on postoperative ultrasonography was found in two patients.
The use of low-volume ultrasound-guided ISBPB is associated with less respiratory depression and hemidiaphragmatic paralysis.
肌间沟臂丛神经阻滞（ISBPB）的并发症通常取决于给药剂量。
本研究的目的是确定超声引导下使用6毫升0.5%左旋布比卡因进行ISBPB是否会减少呼吸抑制和半膈肌麻痹的发生。
招募了在全身麻醉下接受神经阻滞的关节镜肩部手术患者（n = 20）。术前和术后呼吸功能（第1秒用力呼气量百分比和肺活量）无差异。术后超声检查发现两名患者存在半膈肌麻痹。
使用小剂量超声引导下的ISBPB与较少的呼吸抑制和半膈肌麻痹相关。
