Introduction
Effective pain control after video-assisted thoracic surgery (VATS) is critical because of the correlation between postoperative pain and recovery after surgery. Due to the limitations of traditional analgesic modalities, in this study, we present a method of placing a paravertebral catheter (PVC) or an intercostal catheter (ICC) in the sub-pleural space, followed by continuous ropivacaine injection by an infusion pump after surgery.

Aim
To investigate the impact of continuous paravertebral nerve block and intercostal nerve block on postoperative pain control in patients who underwent two-port thoracic surgery.

Material and methods
A total of 269 patients underwent various types of two-port VATS at Hwa Mei Hospital. Among them, we retrospectively compared paravertebral block versus intercostal nerve block to intravenous patient-controlled analgesia after VATS. Data regarding postoperative pain score on postoperative day 0, 1, 2, 3, and discharge day pain score, tramadol requirements, drainage duration, postoperative hospital stay, postoperative complications, and chronic pain 3 months after surgery were collected and analyzed.

Results
Compared with the control group, patients who received a continuous nerve block, including the PVC group and ICC group, had a lower postoperative pain score (p < 0.001), shorter drainage duration (4.63 ±2.84 to 5.61 ±2.66 days, p = 0.004), reduced postoperative hospital stay (6.04 ±3.01 to 7.69 ±3.26 days, p < 0.001), and a reduced frequency of tramadol (0.95 ±1.27 1.79 ±2.13 times, p < 0.001). Additionally, there was no significant difference in chronic pain between groups.

Conclusions
In our study, PVC and ICC appeared to be safe and effective analgesic techniques to reduce postoperative pain, thus shortening the duration of postoperative hospital stay and improving the satisfaction of patients.
