Liposomal Bupivacaine Versus Bupivacaine Hydrochloride for Intercostal Nerve Blockade in Minimally Invasive Thoracic Surgery.

Objective: The objective of this study was to compare the effects of liposomal bupivacaine (Lipo-B) and bupivacaine hydrochloride (B-HCl), in the presence of multimodal analgesia, on postoperative analgesia and opioid consumption in minimally invasive thoracic surgery (MITS) lobectomy.

Methods: Retrospective observational cohort study. Methods: Tertiary care cancer center. Methods: A total of 60 patients who underwent MITS lobectomy and received intercostal nerve blockade (ICNB) with either 0.66% Lipo-B (n = 29) or 0.5% B-HCl (n = 31). Methods: All patients received intravenous patient-controlled analgesia for the first 12 hours postoperatively, followed by opioids and nonsteroidal anti-inflammatory drugs as needed.

Results: Perioperative opioid and nonopioid consumption and pain scores were compared between groups at 12-hour intervals for the first 72 hours. Between the two groups, there were no statistically significant differences in demographic characteristics, intraoperative (p = 0.46) and postoperative opioid consumption, Richmond Agitation-Sedation Scale scores and pain scores upon postanesthesia care unit arrival and after four hours, length of postanesthesia care unit stay (p = 0.84), or length of hospital stay (p = 0.55). Both groups received intra- and postoperative multimodal analgesia.

Conclusions: In this cohort, no differences in opioid consumption or pain scores were observed in the immediate postoperative period following MITS lobectomy between patients given ICNB with Lipo-B and those given ICNB with B-HCl in the presence of multimodal analgesia.
