Summary
Postoperative pain after thoracic surgery is associated with adverse outcomes. The current strategy to prevent postoperative pain is the use of regional anesthesia and analgesic agents. In video-assisted thoracic surgery (VATS), thoracic paravertebral block has become the standard analgesic regimen which results in decreased postoperative pain and opioid consumption. The investigator would like to study the analgesic efficacy of low dose intravenous ketamine infusion during surgery in combination with thoracic paravertebral block on postoperative pain after VATS in a randomized study.
