BACKGROUND: Interscalene brachial plexus block (ISBPB) complications depend usually on the dose administered. METHODS: 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. RESULTS: 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. CONCLUSIONS: The use of low-volume ultrasound-guided ISBPB is associated with less respiratory depression and hemidiaphragmatic paralysis.
