Although surgical treatment is effective and curative, it is associated with many complications in the postoperative period. Acute pain after surgery is one of them. Approximately half of women undergoing breast surgery describe significant post-operative pain (\\>5 on the Visual Analogue Scale; VAS) score that is not always effectively controlled by standard post-operative treatments. Poorly controlled postoperative pain has been associated with impaired functional recovery, delayed discharge from the post-anesthetic care unit, and prolonged hospital stay. In addition, poorly managed acute pain becomes chronic and is described as 'post-mastectomy pain syndrome'. Regional techniques can reduce acute and chronic postoperative pain. The development of ultrasonography (US)-guided regional anesthesia has led to the development of fascial plane blocks. Serratus anterior plan (SAP) block, pectoserratus plan (PECS II) block, and erector spina plan (ESP) block are frequently used for postoperative analgesia in patients undergoing breast surgery. he aim of this study was to evaluate the efficacy of serratus anterior plane (SAP) block, pectoserratus plane (PECS II) block, and erector spinae plane (ESP) block on postoperative acute pain, quality of recovery and chronic pain in breast cancer surgery patients."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'genderBased': True, 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'It is planned to include ASA I-III patients between the ages of 18-65 who are planned to undergo breast cancer surgery', 'genderDescription': 'The patients scheduled for elective breast surgery (modified radical mastectomy, breast conserving surgery, simple mastectomy, axillary lymph node dissection, etc.)', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* elective breast surgery (modified radical mastectomy, breast conserving surgery, simple mastectomy, axillary lymph node dissection, etc.),\n* 18 to 65 years old,\n* American Society of Anaesthesiology (ASA) score I-III\n* body mass index (BMI) \\<32 kg/m2\n\nExclusion Criteria:\n\n* contraindications to the block applications\n* history of mental or neurological disorders\n* history of chronic opioid use\n* chronic alcoholism\n* substance use\n* treatment of chronic pain\n* severe liver and kidney disease\n* uncooperative patients\n* patients scheduled for bilateral mastectomy'}, 'identificationModule': {'nctId': 'NCT06419504', 'briefTitle': 'The Effect of Ultrasonography-guided Fascial Plane Blocks in Breast Cancer Surgery Patients', 'organization': {'class': 'OTHER_GOV', 'fullName': 'Antalya Training and Research Hospital'}, 'officialTitle': 'The Effect of Ultrasonography-guided Pectoserratus Plane Block, Erector Spina Plane Block and Serratus Anterior Plane Block on Postoperative Opioid Consumption, Recovery Quality and Chronic Pain in Breast Cancer Surgery Patients', 'orgStudyIdInfo': {'id': '6/11'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'SAP block group', 'description': 'Before the surgery, US-guided SAP block will be performed', 'interventionNames': ['Other: SAP block group']}, {'label': 'PECS II block group', 'description': 'Before the surgery, US-guided PECS II block will be performed', 'interventionNames': ['Other: PECS II block group']}, {'label': 'ESP block group', 'description': 'Before the surgery, US-guided ESP blockwill be performed', 'interventionNames': ['Other: ESP block group']}, {'label': 'Control group', 'description': 'No intervention', 'interventionNames': ['Other: Control group']}], 'interventions': [{'name': 'SAP block group', 'type': 'OTHER', 'description': 'US-guided SAP block is performed approximately 30 minutes before the surgery in patients undergoing breast cancer surgery in a separate regional anesthesia room with standard anesthesia monitoring.', 'armGroupLabels': ['SAP block group']}, {'name': 'PECS II block group', 'type': 'OTHER', 'description': 'US-guided PECS II block is performed approximately 30 minutes before the surgery in patients undergoing breast cancer surgery in a separate regional anesthesia room with standard anesthesia monitoring.', 'armGroupLabels': ['PECS II block group']}, {'name': 'ESP block group', 'type': 'OTHER', 'description': 'US-guided ESP block is performed approximately 30 minutes before the surgery in patients undergoing breast cancer surgery in a separate regional anesthesia room with standard anesthesia monitoring.', 'armGroupLabels': ['ESP block group']}, {'name': 'Control group', 'type': 'OTHER', 'description': 'No intervention', 'armGroupLabels': ['Control group']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Antalya', 'state': 'Muratpaşa', 'country': 'Turkey (Türkiye)', 'facility': 'University of Health Sciences, Antalya Training and Researh Hospital', 'geoPoint': {'lat': 36.90812, 'lon': 30.69556}}], 'overallOfficials': [{'name': 'Hafizenur O Atalay, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Health Sciences, Antalya Training and Researh Hospital'}, {'name': 'Arzu O Karaveli, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Health Sciences, Antalya Training and Researh Hospital'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Antalya Training and Research Hospital', 'class': 'OTHER_GOV'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
