Abstract
BackgroundLiposomal bupivacaine (LB) is a local analgesic that may be used at the time of surgery to limit postoperative pain around the surgical site. Its efficacy in decreasing pain, decreasing narcotic consumption, decreasing length of stay, and improving mobility is an area of intense research. The purpose of this study was to determine whether LB use was associated with improved patient-reported pain scores in the first 72 h following posterior spinal surgery, decreased postoperative narcotic need, and decreased length of stay. MethodsOne hundred and five patients undergoing elective posterior cervical or lumbar surgery were included in retrospective analysis. Forty-eight patients who received LB intraoperatively were compared with a historical cohort of 56 patients who underwent similar procedures and did not receive postsurgical infiltration with local analgesia. The same pain medication protocol was utilized postoperatively. ResultsDemographics, clinical characteristics, and total morphine milligram equivalents did not differ significantly between the groups. The treatment group averaged a decreased length of stay (1.85 days treatment, 2.68 days control, p = 0.057). Treatment with LB was associated with lower pain levels at 24 h (5.2 treatment, 6.4 control, p = 0.04) and 48–72 h (4.9 treatment, 6.6 control, p = 0.007) after surgery. ConclusionsLB improved patient perception of pain in the acute postoperative time period.Intraoperative LB injection, coupled with focused early mobilization efforts and multimodal pain control, may lead to improved patient-reported outcomes, shorter length of stay, and decreased risk of perioperative complications.
