Paravertebral block combined with serratus anterior plane block after video-assisted thoracic surgery: a prospective randomized controlled trial.

Objectives: Adequate pain management after thoracoscopic surgery is a major issue in the prevention of respiratory complications. The combination of the paravertebral block (PVB) with the serratus anterior plane block (SAPB) may decrease postoperative pain. The objective of this study was to evaluate the impact of the combination of PVB and SAPB on the consumption of morphine and pain after video- or robot-assisted thoracic surgery.
