It is unclear whether intercostal analgesia is as useful in the prevention of postoperative chronic pain as it is for acute pain for video-assisted thoracoscopic surgery (VATS). The purpose of this study was to evaluate the efficacy of perioperative intercostal analgesia for chronic pain via a multimodal analgesic regimen for VATS during 6 months of postoperative follow-up.Methods: We identified 837 cases of VATS from August 2016 to August 2018. Patients were treated by perioperative intercostal analgesia with 0.75% ropivacaine 50 mg through the intercostal catheter every 8 hours until chest tube extubation (INA group) or conventional analgesia with preoperative 0.75% ropivacaine 50 mg at incision once (CON group). Numerical rating scale (NRS) and neuropathic pain were evaluated in 6 months of post-surgery follow-up. Postoperative adverse effects were recorded.Results: In total, there were 419 patients in INA group and 418 patients in CON group. Scores of NRS with motion was lower in INA group at 3 postoperative days (P = 0.032). Occurrence of chronic pain was 28.4% in INA group and 32.8% in CON group at 6 postoperative months, 10.6% of patients experienced increasing pain from 3 to 6 months. Occurrence of considerable neuropathic pain (ID pain score ≥ 2) was 2.1% in INA group and 3.1% in CON group at 6 postoperative months. No differences were found between the two groups. Occurrence of numbness was lower in INA group (6.7% vs 10.5%, P = 0.031), and other pain symptoms did not differ between the groups. The incidence of dizziness, nausea, vomiting and atelectasis was not different between the two groups.Conclusion: In a multimodal analgesic regimen of VATS, perioperative intercostal analgesia with 0.75% ropivacaine infusion 50 mg three times in a day does not have an obvious effect on chronic post-thoracotomy pain.Keywords: chronic pain, neuropathic pain, intercostal analgesia, video-assisted thoracoscopic surgery
