Video-assisted thoracoscopic surgeries (VATS) include significant postoperative acute and chronic pain because of trocar site tissue damages, intercostal nerve injuries and related inflammatory responses. Poorly controlled pain in the early postoperative period usually causes chronic pain, and also affects patients' physiotherapy, mobilization and daily function.
Our hypothesis in this study is 'thoracic paravertebral block (TPVB) is associated with an improvement in control of acute and chronic pain after VATS compared to systemic analgesia.
