The Effect of Paravertebral Block, Intertransverse Block, and Erector Spinae Plane Block on Postoperative Opioid Consumption and Pain Scores in Video-assisted Thoracic Surgery: a Prospective Observational Study

What this Trial Is About

Researchers are evaluating the effects of different ultrasound-guided regional anesthesia techniques on postoperative opioid use and pain levels in patients undergoing video-assisted thoracic surgery (VATS). Although VATS is known for faster recovery and less pain compared to traditional thoracotomy, it can still lead to acute and chronic postoperative pain that may affect recovery and increase pulmonary complications. This study aims to compare three specific regional anesthesia methods to improve pain management after VATS. The study compares three groups of patients receiving different ultrasound-guided nerve blocks before surgery: paravertebral block, intertransverse process block, and erector spinae plane block. Each block is performed under standard anesthesia monitoring prior to the surgical procedure. These regional anesthesia techniques are part of a multimodal approach to control pain and reduce opioid consumption after surgery. Participants will undergo the assigned nerve block before VATS and will be monitored for opioid use during the first 24 hours after surgery. Pain scores will be assessed using the Numerical Rating Scale during the same period, and chronic pain presence will be evaluated three months postoperatively. The study tracks opioid consumption and pain levels to understand which block provides better postoperative analgesia while ensuring patient safety and recovery quality.
