Effect of Intraoperative Nefopam on Postoperative Analgesia in Living Liver Donors Undergoing Laparoscopic Hepatectomy with Transversus Abdominis Plane Block: A Propensity Score-Matched Study

Year: 2025

Type: article

Abstract: Laparoscopic surgery reduces tissue trauma and accelerates recovery, but postoperative pain remains a concern. Opioids are effective but have adverse effects, highlighting the need for multimodal analgesia. Nefopam, a non-opioid analgesic, provides pain relief without respiratory depression or dependence. This study aims to investigate the efficacy of intravenous nefopam combined with a transversus abdominis plane (TAP) block in living liver donors undergoing laparoscopic hepatectomy. This retrospective cohort analysis was conducted on 452 adult living donors who underwent laparoscopic hepatectomy with a TAP block between August 2013 and August 2018 at a single tertiary medical center. After propensity score matching, 296 patients were included, with 148 in the nefopam group and 148 in the non-nefopam group. The primary outcomes assessed were pain scores using the Numeric Rating Scale (NRS) at 1, 4, 8, 12, and 24 h postoperatively, opioid consumption, postoperative nausea and vomiting, and nefopam-related adverse effects. Nefopam significantly reduced NRS at 1, 4, and 8 h postoperatively (p < 0.001) and decreased fentanyl use in the post-anesthesia care unit (26.0 ± 32.2 μg vs. 60.5 ± 37.9 μg, p < 0.001) and total intravenous patient-controlled analgesia volume (p < 0.001). The incidence of postoperative nausea and vomiting and severe opioid-related complications did not differ between groups. Nefopam-related side effects were mild and self-limiting. Nefopam combined with a TAP block effectively reduces postoperative pain and opioid consumption in living liver donors, supporting its role in multimodal analgesia. Further research is needed to explore its broader applications.
