Postoperative acute and chronic pain is frequently observed in patients undergoing video assisted thoracoscopic surgery (VATS). This prolongs the discharge time of patients and increases the frequency of postoperative pulmonary complications. Recently, alternative analgesic methods such as thoracic paravertebral block (TPVB), erector spinae plane block (ESPB), and serratus anterior plane block (SAPB) which are thought to have less side effects than thoracic epidural analgesia, have been used. Among these methods, ultrasound (US) guided TPVB is the most preferred method. In addition, ESPB and SAPB application is increasing in patients undergoing VATS. In the literature, the number of cases performed with ESPB and SAPB and randomized controlled prospective studies with ESPB and SAPB are increasing. In this study, it is planned to compare the effects of US-guided SAPB and ESPB on postoperative acute and chronic pain in patients undergoing VATS.
