However, very few studies have evaluated the effect of various methods of anaesthesia on the NLR and PLR.\n\nThis is the first study to investigate the effect of regional anaesthesia on the pain managementonse expres and stress respsed by the NLR and PLR in patients undergoing knee replacement surgery."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '100 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with ASA classification I-III, Aged 20-90 years, Who will be scheduled for knee arthroplasty under spinal anaesthesia.\n\nExclusion Criteria:\n\n* patients who have a history of bleeding diathesis,\n* take anticoagulant therapy,\n* have a History of chronic pain before surgery,\n* have Multiple trauma, cannot assess their pain (dementia),\n* have been operated on under general anaesthesia,\n* have an infection in the area and do not accept the procedure'}, 'identificationModule': {'nctId': 'NCT06302218', 'briefTitle': 'ESPB vs iPACK+ACB in Total Knee Arthroplasty', 'organization': {'class': 'OTHER', 'fullName': 'Poznan University of Medical Sciences'}, 'officialTitle': 'Erector Spinae Plane Block vs. iPACK Block With Adductor Canal Block for Pain Management in Patients Undergoing Total Knee Replacement', 'orgStudyIdInfo': {'id': '5/2024'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'iPACK + ACB', 'description': 'spinal anesthesia\n\n\\+ ultrasound guided iPACK (20ml 0,2% ropivacaine) with ACB (10ml 0.5% ropivacaine)', 'interventionNames': ['Drug: Ropivacaine 0.2% Injectable Solution']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Erectro Spinae Plane Block', 'description': 'spinal anesthesia\n\n\\+ ultrasound guided ESPBk - 20ml 0,2% ropivacaine', 'interventionNames': ['Drug: Ropivacaine 0.2% Injectable Solution']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Control group', 'description': 'Only spinal anesthesia - No peripheral nerve block', 'interventionNames': ['Drug: control group']}], 'interventions': [{'name': 'Ropivacaine 0.2% Injectable Solution', 'type': 'DRUG', 'otherNames': ['iPACK + ACB'], 'description': 'iPACK block + Adductor Canal Block', 'armGroupLabels': ['iPACK + ACB']}, {'name': 'Ropivacaine 0.2% Injectable Solution', 'type': 'DRUG', 'otherNames': ['ESPB'], 'description': 'Erector Spinae Plane Block', 'armGroupLabels': ['Erectro Spinae Plane Block']}, {'name': 'control group', 'type': 'DRUG', 'otherNames': ['only spinal anesthesia'], 'description': 'only spinal anesthesia', 'armGroupLabels': ['Control group']}]}, 'contactsLocationsModule': {'locations': [{'zip': '61-701', 'city': 'Poznan', 'state': 'Poznań', 'country': 'Poland', 'facility': 'Poznan University of Medical Sciences', 'geoPoint': {'lat': 52.40692, 'lon': 16.92993}}], 'centralContacts': [{'name': 'Malgorzata Domagalska, Ph.D.', 'role': 'CONTACT', 'email': 'm.domagalska@ump.edu.pl', 'phone': '608762068'}, {'name': 'Małgorzata Domagalska, Ph.D.', 'role': 'CONTACT', 'email': 'm.domagalska@ump.edu.pl', 'phone': '61 873 83 03'}], 'overallOfficials': [{'name': 'Łukasz Łapaj, Ph.D.', 'role': 'STUDY_CHAIR', 'affiliation': 'Poznań University of Medical Sciences'}]}, 'ipdSharingStatementModule': {'infoTypes': ['STUDY_PROTOCOL', 'SAP', 'ICF', 'CSR', 'ANALYTIC_CODE'], 'timeFrame': '6 month after study completion', 'ipdSharing': 'YES', 'accessCriteria': 'from the corresponding author on the resonable request'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Poznan University of Medical Sciences', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
