Eligible patients are going to be randomized to receive sevoflurane or desflurane, as a maintenance anesthetic, during the surgery. Tissue oxygen saturation and microcirculatory changes, such as an occlusion and recovery slope, during vascular occlusion test will be recorded during the surgery. The primary end point of the study is the difference in tissue oxygen saturation between the groups.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '90 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* scheduled for off-pump coronary artery bypass surgery\n\nExclusion Criteria:\n\n* any deformity or vascular abnormalities on upper arms\n* cannot receive sevoflurane or desflurane for any reason (muscular diseases, etc)\n* uncontrolled diabetes\n* peripheral vascular disease\n* severe renal dysfunction (end-stage renal disease)\n* refuse to enroll\n* pregnant'}, 'identificationModule': {'nctId': 'NCT03209193', 'briefTitle': 'Effect of Anesthetics on Microcirculation in Patients Undergoing Off-pump Coronary Artery Bypass Surgery', 'organization': {'class': 'OTHER', 'fullName': 'Seoul National University Hospital'}, 'officialTitle': 'Effect of Anesthetics on Microcirculation in Patients Undergoing Off-pump Coronary Artery Bypass Surgery', 'orgStudyIdInfo': {'id': 'OPCAB_SEVO vs DES'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Sevoflurane', 'description': 'Sevoflurane (2 vol%) use as a maintenance volatile anesthetic drug during the surgery', 'interventionNames': ['Drug: Sevoflurane']}, {'type': 'EXPERIMENTAL', 'label': 'Desflurane', 'description': 'Desflurane (6 vol%) use as a maintenance volatile anesthetic drug during the surgery', 'interventionNames': ['Drug: Desflurane']}], 'interventions': [{'name': 'Sevoflurane', 'type': 'DRUG', 'description': 'Sevoflurane use as main anesthetic drug during the surgery', 'armGroupLabels': ['Sevoflurane']}, {'name': 'Desflurane', 'type': 'DRUG', 'description': 'Desflurane use as main anesthetic drug during the surgery', 'armGroupLabels': ['Desflurane']}]}, 'contactsLocationsModule': {'locations': [{'zip': '03080', 'city': 'Seoul', 'country': 'South Korea', 'facility': 'Seoul National University Hospital', 'geoPoint': {'lat': 37.566, 'lon': 126.9784}}], 'overallOfficials': [{'name': 'Youn Joung Cho, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Seoul National University Hospital'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Seoul National University Hospital', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Clinical Professor', 'investigatorFullName': 'Youn Joung Cho, MD', 'investigatorAffiliation': 'Seoul National University Hospital'}}}}
