At present, there is still a lack of sufficient clinical research evidence to prove whether anesthesia exposure has long-term effects on neurodevelopment. The existing clinical research data suggests that a single short-time anesthesia exposure in young children does not affect long-term neurodevelopmental outcomes. Early onset scoliosis, including congenital scoliosis, is a type of scoliosis deformity that occurs before the age of 10. Posterior scoliosis correction surgery is one of the common treatment. There is currently no research indicating the impact of early single or multiple long-duration anesthesia exposure on the neurological development of children with congenital scoliosis. The aim of this study is to determine the long-term effect of general anesthesia exposure on neurocognitive function and behavior in children with congenital scoliosis, in order to provide reference for related clinical work.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '16 Years', 'minimumAge': '6 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Children diagnosed with congenital scoliosis', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Diagnosed with congenital scoliosis\n* 6-16 years old at the time of assessment\n\nExclusion Criteria:\n\n* Cognitive impairment caused by congenital, traumatic or other reasons;\n* Existence of mental or psychological disorders;\n* There are factors that may affect neurological development, including any known central nervous system disease, neurological injury, or history of neonatal asphyxia;\n* Unable to cooperate with cognitive function tests;\n* The child is unable to communicate in Chinese.'}, 'identificationModule': {'nctId': 'NCT06315933', 'briefTitle': 'Anesthesia Neurodevelopmental Impact in Congenital Scoliosis Children', 'organization': {'class': 'OTHER', 'fullName': 'Peking Union Medical College Hospital'}, 'officialTitle': 'Long-term Effect of General Anesthesia Before School Age on Neurodevelopment in Children With Congenital Scoliosis', 'orgStudyIdInfo': {'id': 'S-K1093'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Unexposed', 'description': 'Children unexposed to general anesthesia before school age (\\<=6y)'}, {'label': 'Singly exposed', 'description': 'Children singly exposed to general anesthesia before school age (\\<=6y)', 'interventionNames': ['Procedure: General anesthesia']}, {'label': 'Multiply exposed', 'description': 'Children multiply exposed to general anesthesia before school age (\\<=6y)', 'interventionNames': ['Procedure: General anesthesia']}], 'interventions': [{'name': 'General anesthesia', 'type': 'PROCEDURE', 'description': 'General anesthesia including inhaled and intravenous', 'armGroupLabels': ['Multiply exposed', 'Singly exposed']}]}, 'contactsLocationsModule': {'locations': [{'zip': '100730', 'city': 'Beijing', 'state': 'Beijing Municipality', 'status': 'RECRUITING', 'country': 'China', 'contacts': [{'name': 'Lulu Ma, Dr.', 'role': 'CONTACT', 'email': 'malulu@pumch.cn', 'phone': '0086-010-13811049619'}], 'facility': 'Peking Union Medical College Hospital', 'geoPoint': {'lat': 39.9075, 'lon': 116.39723}}], 'centralContacts': [{'name': 'Lulu Ma, Dr.', 'role': 'CONTACT', 'email': 'malulu@pumch.cn', 'phone': '0086-10-13811049619'}, {'name': 'Ziyi Dai, Dr.', 'role': 'CONTACT', 'email': 'daiziyi@pumch.cn', 'phone': '0086-10-18611703606'}], 'overallOfficials': [{'name': 'Lulu Ma, Dr.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Peking Union Medical College Hospital'}]}, 'ipdSharingStatementModule': {'infoTypes': ['STUDY_PROTOCOL', 'SAP', 'ICF', 'CSR'], 'timeFrame': 'starting 1 year after the results are published', 'ipdSharing': 'YES', 'description': 'IPD that underlie results in a publication', 'accessCriteria': 'IPD is available on appropriate request from the Principle Investigator by email'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Peking Union Medical College Hospital', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Chief physician, Professor', 'investigatorFullName': 'Lulu Ma', 'investigatorAffiliation': 'Peking Union Medical College Hospital'}}}}
