Abstract: Continuous wound infusion analgesia (CWA) with local anesthetics is a loco-regional anesthetic approach for multimodal analgesia management in surgical procedures. This study analyzed whether the combination of intravenous patient-controlled analgesia (PCA) and CWA would be more effective than PCA alone for postoperative analgesia and in preventing chronic postsurgical pain syndrome (PSPS) after thoracic surgeries. We enrolled 166 patients after propensity score matching, the PCA alone (PCA group, n = 83) and the combination of PCA and CWA (PCA-CWA group, n = 83), through a review of electronic medical records. The primary endpoint was the numeric rating scale (NRS) at postoperative days 1, 2, 3, 4, and 5. The secondary endpoint was the presence of PSPS at 3 and 6 months postoperatively. The NRS were lower in the PCA-CWA group than in the PCA group throughout the postoperative period ( p < 0.001). The sedation incidence was lower in the PCA-CWA group (1.2%) than in the PCA group (9.6%) ( p = 0.034), and there was no significant difference in other postoperative complications or in the incidence of PSPS ( p = 1.000). The combination of intravenous PCA and CWA is an effective postoperative analgesic modality for thoracic surgery.
