Detailed Description

Although less invasive, postoperative analgesia remains challenging in patients undergoing uniportal video-assisted thoracic surgery (VATS).

Adequate postoperative pain relief is imperative to hasten functional recovery, accelerate discharge from the hospital, and reduce chronic postsurgical pain.
