Abstract
Background: Pleurectomy/decortication (P/D), a surgical procedure for malignant pleural mesothelioma (MPM), is a highly invasive surgery requiring prolonged hospitalization. Previous studies have reported that postoperative analgesia using regional anesthesia contributes to shorter hospital stays after surgery under general anesthesia by reducing acute postoperative pain. However, the association between postoperative analgesia and the length of hospital stay (LOHS) following P/D has not been evaluated. Objectives: To evaluate the association between postoperative analgesia and postoperative LOHS after P/D. Methods: This single-institution observational study enrolled consecutive adult patients undergoing P/D under general anesthesia, who postoperatively received either intertransverse process block (ITPB) or continuous intravenous (IV) fentanyl infusion as postoperative analgesia between March 2022 and February 2023. Results: Among all enrolled patients with ASA physical status II or III (n = 60), postoperative analgesia was administered using either continuous ITPB (n = 19) or continuous IV fentanyl infusion (n = 41). Multivariable logistic regression analysis revealed that postoperative analgesia with continuous ITPB (P = 0.007), a lower incidence of major complications after surgery (P = 0.034), and female sex (P = 0.033) were significantly associated with a shorter postoperative LOHS. In subgroup analysis, patients who received continuous ITPB had significantly lower postoperative LOHS, lower postoperative serum C-reactive protein levels on postoperative day (POD) 3, and reduced acute postoperative pain on POD3 compared to those who received continuous IV fentanyl infusion. Conclusions: Postoperative analgesia using continuous ITPB appears to be associated with a reduction in LOHS following P/D for MPM under general anesthesia.
