The feasibility of thoracoscopic-guided intercostal nerve block during uniportal video-assisted thoracoscopic lobectomy of the lung.

BACKGROUND

Uniportal thoracoscopic surgery has become widely accepted for its favourable outcomes with regard to pain. However, post-operative pain is still a concern associated with thoracic surgery. The objective of this study was to evaluate the post-operative pain of patients undergoing uniportal video-assisted thoracoscopic surgery (VATS) lobectomies using an intra-operative intercostal nerve block.

METHODS

All consecutive patients undergoing uniportal VATS lobectomies between October 2018 and October 2019 were reviewed retrospectively. Twenty consecutive patients in Group A underwent uniportal VATS lobectomies without intra-operative intercostal nerve blocks. The other 20 consecutive patients in Group B underwent uniportal VATS lobectomies with intra-operative intercostal nerve blocks. Numeric Pain Rating Scale (NRS) scores were recorded at 1, 12 and 24 h postoperatively. The number of anti-inflammatory drugs (non-steroidal anti-inflammatory drug [NSAIDs]) consumed until the time of chest tube removal was also recorded.

RESULTS

There was no difference between the groups with regard to sex, age, chest tube duration, length of stay, operative time or laterality. There was a significant difference in post-operative NRS scores at 1 h (P < 0.001) and 12 h (P = 0.014) between the groups. The NSAID consumption was significantly lower in Group B than in Group A (P = 0.038).

CONCLUSION

Intra-operative intercostal nerve blocks with bupivacaine provided immediate post-operative pain relief and reduced post-operative opioid consumption in patients who underwent uniportal VATS lobectomies.
