Assessment of feasibility of opioid-free anesthesia combined with preoperative thoracic paravertebral block and postoperative intravenous patient-controlled analgesia oxycodone with non-opioid analgesics in the perioperative anesthetic management for video-assisted thoracic surgery.

Introduction: This study, conducted between December 2015 and March 2018 at a single university hospital, explored the feasibility and safety of opioid-free anesthesia combined with preoperative thoracic paravertebral block (ThPVB) for patients undergoing elective video-assisted thoracoscopic surgery (VATS). The aim was to assess the impact of this approach on postoperative pain levels and opioid consumption.

Material And Methods: Sixty-four patients scheduled for elective VATS were randomly assigned to either the intervention group, receiving opioid-free anesthesia with ThPVB, or the control group, managed with standard general anesthesia.
