Abstract

Regional nerve blocks are an effective method of managing acute pain associated with surgery. The relative benefit of preoperative versus postoperative peripheral nerve blocks is not entirely clear. The primary aim of this study was to determine differences in pain scores in patients undergoing preoperative block versus postoperative block versus no block. We hypothesized that patients receiving preoperative blocks would have reduced pain scores and decreased opioid use in the immediate postoperative period. We conducted a retrospective cohort analysis of 302 consecutive patients undergoing unilateral open reduction and internal fixation of ankle fracture under general anesthesia. We identified 3 groups: preoperative block, postoperative block, or no block. Data obtained from our electronic medical records included demographic information, postanesthesia care unit length of stay, pain scores obtained preoperatively, upon arrival to the postanesthesia care unit, and upon discharge from the postanesthesia care unit as well as intraoperative and postanesthesia care unit opioid utilization. Patients receiving preoperative block had significantly lower pain scores, less intraoperative or postanesthesia care unit opioid use, and shorter postanesthesia care unit dwell time compared with patients receiving postoperative block or no block. Preoperative popliteal sciatic and adductor canal blocks in patients undergoing ankle fracture surgery appears to be more effective than either postoperative block or no block.
