Comparison of Patient Satisfaction between Brachial Plexus Block (Axillary Approach) and General Anesthesia for Surgical Treatment of Distal Radius Fractures: A Historical Cohort Study

摘要

Background: Distal radius fracture surgery is performed under general (GA) or regional anesthesia with brachial plexus block (NB). Whether anesthesia type affects patient outcomes is unclear. This study retrospectively compared patient satisfaction between GA and NB after surgery. Methods: This was a historical cohort study of 80 (34 GA and 46 NB) patients who underwent volar plate fixation of distal radius fractures. Propensity score analysis was used to generate a set of matched cases (NB) and controls (GA), yielding 14 matched patient-pairs. The simplified patient satisfaction scale was compared for primary outcomes. Secondary outcomes were anesthesia and surgery duration, hospital stay length, adverse events, postoperative analgesic requirement, and wrist range of motion (ROM) 2 weeks and 3 months postoperatively. Results: After propensity score matching, patients in almost all cases in both groups were "Satisfied" (effect size: 0.1, p = 0.572), indicating little significant difference. Significant differences in adverse events and postoperative analgesic use observed before matching disappeared after matching. Anesthesia duration and hospital stay length were significantly shorter in the NB group (effect size: -1.27 and -0.77, p = 0.00074 and p = 0.0388, respectively), as was surgery duration (effect size: -0.84, p = 0.0122) after matching. Similar to before matching, wrist ROM significantly improved in the NB group (effect size: 1.11, p = 0.0279) in the early postoperative period, but the difference disappeared at 3 months postoperatively. Conclusions: Patient satisfaction between distal radius fracture surgery under GA and NB was similar. Nerve block could help shorten hospital stay length and surgery duration and improve postoperative functional recovery.
