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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age between 18 and 65 years\n* American Society of Anesthesiologists physical status I-II-III\n* Body mass index between 18-30 kg/m2\n* Patients undergoing elective video assiste thoracoscopic surgery\n\nExclusion Criteria:\n\n* Advanced cancer\n* History of chronic analgesic therapy\n* History of local anesthetic allergy\n* Infection in the intervention area\n* Patients with bleeding disorders'}, 'identificationModule': {'nctId': 'NCT05160961', 'briefTitle': 'US-Guided SAPB Versus ESPB on Acute and Chronic Pain After VATS', 'organization': {'class': 'OTHER', 'fullName': 'Atatürk Chest Diseases and Chest Surgery Training and Research Hospital'}, 'officialTitle': 'Comparison of the Effects of Ultrasound-guided Serratus Anterior Plane Block and Erector Spinae Plane Block on Postoperative Acute and Chronic Pain for Patients Who Underwent Video-assisted Thoracoscopic Surgery.', 'orgStudyIdInfo': {'id': 'E.Kurul-E1-21-2142'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Serratus Anterior Plane Block', 'description': 'Following the visualization of the anatomical structures, the nerve block needle will be advanced via the in-plane technique beneath the serratus anterior muscles until the interfascial space was reached.
