Regional anesthesia for clavicle fracture surgery is safe and effective

Historically, clavicle fracture repairs have been performed with patients under general anesthesia. However, in the past few years, the combination of an interscalene brachial plexus block and a modified superficial cervical plexus block has been described to provide adequate anesthesia for clavicle fracture surgery, with the added benefit of postoperative analgesia. In March 2013, members of our anesthesiology department began using this block with sedation for a subset of patients undergoing clavicle fracture fixation.

This study was a retrospective review of patients who underwent clavicle fracture repair at a single institution between June 2014 and November 2017. The decision on the type of anesthesia (regional vs. general) was made jointly by the patient, anesthesiologist, and surgeon. Demographic data, relevant perioperative times, and intraoperative pain medication consumption were recorded, and comparisons of these variables were made between the regional and general anesthesia groups.

A total of 110 patients with 110 fractures were included. Of these patients, 52 received only regional anesthesia with the combined block whereas 58 received general anesthesia with an interscalene brachial plexus block. No major anesthetic-related complications were noted in any patients, and there were no cases in which regional anesthesia had to be converted to general anesthesia because of block failure. The anesthesia start time was significantly longer in the general anesthesia group (29 minutes vs. 20 minutes, P = .022), as was the total case time (164 minutes vs. 131 minutes, P < .001). Patients in the general anesthesia group required significantly more intraoperative fentanyl to be administered (207 μg vs. 141 μg, P = .002).

Regional anesthesia using a combined brachial plexus and modified superficial cervical plexus block is a reliable, efficacious technique. The combined block appears to be a reasonable alternative to general anesthesia with an interscalene brachial plexus block, and it may have benefits regarding the anesthesia start time and total case time.
