Abstract

Purpose: No final conclusion has yet been reached on characteristics of postoperative pain and pain-related factors after video-assisted thoracoscopic surgery (VATS). This study was designed to explore features of acute severe pain and chronic post-surgical pain (CPSP), and the pain-related factors of VATS.

Patients and methods: Data of patients who underwent VATS for lung cancer in Cancer Hospital, Chinese Academy of Medical Sciences between March 2017 and January 2019 were reviewed in this retrospective study. A numerical rating scale (NRS) was used for evaluating the intensity of postoperative pain including no pain (NRS=0), mild pain (NRS=1-3), moderate pain (NRS=4-6), and severe pain (NRS=7-10). Pain intensity was assessed daily within a week after operation, and also evaluated at 3 months postoperatively.

Results: One hundred and five (3.4%) of the 3072 patients enrolled experienced severe pain (NRS=7-10) on the 1st day after operation, and 17 (0.6%) on the 2nd day. Smoking history, three-port VATS, prolonged operation time, and without patient-controlled analgesia (PCA) were correlated to increased incidence of severe pain. Among all patients, 237 (7.7%) cases generated CPSP, and VATS type, operation time, duration of drainage, and severe pain on the 1st day were four independent risk factors related to CPSP.

Conclusion: Patients seemed to experience a lower incidence of acute severe pain and CPSP after VATS than traditional open surgery. Acute severe pain was correlated with smoking history, VATS type, operation time, and PCA; VATS type, operation time, duration of drainage, and severe pain on the 1st day postoperatively were four independent risk factors of CPSP.

Keywords: NRS; VATS; acute severe pain; chronic post-surgical pain; risk factor.
