Study DesignRetrospective Controlled Cohort.ObjectiveTo evaluate the effect of intraoperative liposomal bupivacaine (LB) via Erector Spinae Plane Block (ESPB) on postoperative adolescent idiopathic scoliosis (AIS) patients with and without patient-controlled analgesia (PCA).Summary Of Background DataPain control after posterior spinal fusion (PSF) for AIS includes opioids and other modalities. The goal of these modalities is to reduce pain and opioid consumption. Two new modalities for pain control include LB and ESPB. There are scant studies on these modalities tested in concert on patients undergoing PSF for AIS.Methods72 consecutive patients with AIS who underwent PSF separated into patients who had a PCA (Group A) as part of their postoperative pain management and those who did not (Group B). Opioid consumption was measured via Morphine Milligram Equivalents (MME). Pain scores were measured via the Visual Acuity Score (VAS). Patient mobility was measured by steps taken. These were measured by function of postoperative day from surgery (POD).ResultsGroup B had significant lower MME at every point after surgery, most notably throughout the entire hospital stay (99.8 vs. 200.7). Postoperative pain scores in Group B were the same if not better than Group A. There was no difference in mobility between the cohorts. The Group B had lower LOS (3.7 s 4.1).ConclusionIn postoperative PSF for AIS patients receiving LB via ESPB, those who did not receive a PCA had lower opioid consumption without worse pain scores or mobility and had a lower LOS. Adding LB via ESPB to postoperative pain regimens effectively replaces a PCA by providing the same pain control and reducing overall opioid consumption and LOS.Copyright © 2024 Wolters Kluwer Health, Inc.
