A Comparison of Combined Superficial Cervical Plexus Block and Interscalene Brachial Plexus Block with General Anesthesia for Clavicle Surgery: Pilot Trial

Abstract

OBJECTIVE: Recently, the cases about successful regional anesthesia using combined superficial cervical plexus block and interscalene brachial plexus block for clavicle surgery have been reported. The aim of this study was to compare regional anesthesia using combined superficial cervical plexus block and interscalene brachial plexus block with general anesthesia. METHODS: In this prospective randomized study, 26 patients scheduled for elective clavicle surgery were divided into two groups: the first group was general anesthesia group (GA group, n=13) and the second group for peripheral nerve block group (PNB group, n=13). Standardized general anesthesia was done to the patients assigned to the GA group and ultrasonography‐guided combined superficial cervical plexus block and interscalene brachial plexus block was done to the patients assigned to the PNB group. Postoperative sedation scale was assessed at post‐anesthesia care unit, and pain scale using 10‐cm Visual Analog Scale (VAS) was assessed at immediate postoperative, 30 minutes, 1 hour, 6 hours, and 24 hours. Patients needed additional analgesics, and time for first analgesic demand and duration from surgery to discharge was recorded. RESULTS: The pain VAS scales were less in PNB group than GA group from immediate postoperative time to 6 hours. The patients' immediate postoperative sedation scale less than 4 were significantly less in PNS group than GA group. The duration from surgery to discharge was shorter in PNS group than GA group. CONCLUSION: Regional anesthesia using combined superficial cervical plexus block and interscalene brachial plexus block is a successful alternative to general anesthesia for clavicle surgery.
