Postoperative effective pain treatment provides early mobilization and shorter hospital stay. The US-guided erector spina plane block (ESPB) may be used for postoperative pain treatment following breast surgery. It is a novel interfascial block that was defined by Forero. Rhomboid intercostal block (RIB) is a novel block and was first described by Elsharkawy et al. Local anesthetic solution is administrated between the rhomboid muscle and intercostal muscles over the T5-6 ribs. It has been reported that RIB may provide effective analgesia management for several breast surgeries.\n\nThe primary aim of the study is to compare postoperative pain scores (VAS), and the secondary aim is to evaluate postoperative opioid consumption, adverse effects related with opioids (allergic reaction, nausea, vomiting).', 'detailedDescription': 'Postoperative pain is an important issue in patients underwent mastectomy and axillary dissection surgery. Postoperative effective pain treatment provides early mobilization and shorter hospital stay, thus complications due to hospitalization such as infection and thromboembolism may be reduced.\n\nVarious methods may be performed to reduce the use of systemic opioids and for effective pain treatment following mastectomy and axillary dissection surgery. Ultrasound (US)-guided interfascial plane blocks have been used increasingly due to the advantages of ultrasound in anesthesia practice. Rhomboid intercostal block (RIB) is a novel block and was first described by Elsharkawy et al. Local anesthetic solution is administrated between the rhomboid muscle and intercostal muscles over the T5-6 ribs 2-3 cm medially of the medial border of the scapula. RIB targets both the posterior rami and lateral cutaneous branches of the thoracic nerves and provides analgesia for the hemithorax from T2 to T9. It has been reported that RIB may provide effective analgesia management for several breast surgeries.\n\nThe US-guided erector spina plane block (ESPB) is defined by Forero et al. ESPB provides thoracic analgesia at T5 level and abdominal analgesia at T7-9 level. ESPB contains a local anesthetic injection into the deep fascia of erector spinae. Visualization of sonoanatomy is easy, and the spread of local anesthesic agents can be easily seen under the erector spinae muscle. Thus, analgesia occurs in several dermatomes with cephalad-caudad way. In the literature, it has been reported that ESP block provides effective analgesia after several surgeries such as open heart surgery, breast surgery, thoracoscopic and abdominal operations.\n\nThe aim of this study is to evaluate the efficacy of the US-guided ESPB and RIB for postoperative analgesia after mastectomy and axillary dissection surgery. The primary aim is to compare postoperative pain scores (VAS), and the secondary aim is to evaluate opioid consumption, adverse effects related with opioids (allergic reaction, nausea, vomiting).'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'genderBased': True, 'genderDescription': 'Female patients who will undergo breast surgery will be included', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* American Society of Anesthesiologists (ASA) classification I-II\n* Scheduled for mastectomy and axillary dissection surgery under general anesthesia\n\nExclusion Criteria:\n\n* receiving anticoagulant treatment,\n* known study drugs allergy,\n* opioid addiction\n* infection of the skin at the site of the block,\n* pregnancy or lactation,'}, 'identificationModule': {'nctId': 'NCT04752150', 'briefTitle': 'ESPB and RIB for Pain Management Following Mastectomy Surgery', 'organization': {'class': 'OTHER', 'fullName': 'Medipol University'}, 'officialTitle': 'Comparison of Ultrasound-Guided Erector Spinae Plane Block and Rhomboid Intercostal Block for Pain Management Following Mastectomy Surgery', 'orgStudyIdInfo': {'id': 'Medipol Hospital 18'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Group ESPB = Erector spinae plane block group', 'description': 'In group ESPB, ESPB will be performed with patients in the lateral decubitus position while the surgical site up.
