US-Guided ESPB Versus TPVB on Acute and Chronic Pain After VATS

The Effect of Ultrasound Guided Erector Spinae Plane Block Versus Thoracic Paravertebral Block on Acute and Chronic Pain After Video-Assisted Thoracic Surgery

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) and erector spinae plane block (ESPB), 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 application is increasing in patients undergoing VATS. In the literature, the number of cases performed with ESPB and randomized controlled prospective studies with ESPB are increasing. In this study, it is planned to compare the effects of US-guided TPVB and ESPB on postoperative acute and chronic pain in patients undergoing VATS.
