Studies suggest that intraoperative hypothermia is an important risk factor of postoperative delirium, which is associated with worse early and long-term outcomes. Furthermore, perioperative hypothermia increases stress responses and provokes immune suppression, which might promote cancer recurrence and metastasis. In a recent trial, targeted temperature management reduced intraoperative hypothermia and emergence delirium. There was also a trend of reduced postoperative delirium, although not statistically significant. This trial is designed to test the hypothesis that intraoperative targeted temperature management may reduce postoperative delirium and improves progression-free survival in older patients recovering from major cancer surgery.",[65,26,66,67,68],"Cancer Surgery","Targeted Temperature Management","Postoperative Delirium","Long-term Survivors",[70,71,72,73,74],"Cancer surgery","Intraoperative hypothermia","Targeted temperature management","Postoperative delirium","Long-term survival","2026-06-18",{"date":77,"type":41},"2026-06-23",{"date":79,"type":41},"2024-05-29",{"date":81,"type":21},"2032-06",{"name":83,"class":48},"Peking University First Hospital",36,{"id":86,"slug":87,"hasResults":11,"nctId":88,"briefTitle":89,"officialTitle":90,"acronym":4,"eligibilityCriteria":91,"healthyVolunteers":11,"sex":92,"minAge":17,"maxAge":4,"enrollmentInfo":93,"targetDuration":4,"studyType":22,"phases":4,"briefSummary":95,"conditions":96,"keywords":99,"overallStatus":103,"whyStopped":4,"lastUpdateSubmitDate":104,"lastUpdatePostDateStruct":105,"startDateStruct":107,"completionDateStruct":109,"leadSponsor":111,"locationsCount":113},"100620123","predicting-hypothermia-in-gynecological-laparoscopic-surgery-using-machine-learning-100620123","NCT07353528","Predicting Hypothermia in Gynecological Laparoscopic Surgery Using Machine Learning","Development and Validation of a Machine Learning Model to Predict Hypothermia in Gynecological Laparoscopic Surgery Based on Preoperative Clinical Indicators: A Multicenter Prospective Cohort Study","Inclusion Criteria:\n\n* Female patients aged 18 years or older.\n* Patients scheduled for laparoscopic surgery.\n\nExclusion Criteria:\n\n* Preoperative body temperature exceeding 37.5°C or below 36.0°C.\n* History of hypothyroidism or hyperthyroidism.\n* Patients with thermoregulatory dysfunction, such as severe infection or central nervous system disorders.\n* Patients who refuse to sign the informed consent form.","FEMALE",{"count":94,"type":21},1000,"Brief Title: Predicting Hypothermia in Gynecological Laparoscopic Surgery Using Machine Learning\n\nBrief Summary: This study aims to develop and validate a machine learning model for predicting intraoperative hypothermia (IOH) in patients undergoing gynecological laparoscopic surgery based on preoperative clinical indicators. This prospective, multicenter case-control study will enroll female patients aged 18 years and older who are scheduled for laparoscopic surgery across multiple hospitals from 2026 to 2027. The primary objective is to identify high-risk patients who may experience IOH, defined as a core temperature below 36.0°C during surgery.\n\nParticipants will be classified into two groups: the IOH group, consisting of patients who experience hypothermia, and the normal temperature group, comprising patients who maintain a core temperature of 36.0°C or higher. Data collection will include demographics, comorbidities, surgical details, anesthesia information, and preoperative laboratory results.\n\nThe primary outcome measure will be the area under the curve (AUC) of the model, assessing its predictive performance at various thresholds. Secondary outcomes will include sensitivity, positive predictive value, negative predictive value, and F1 score. The study hypothesizes that the developed machine learning model will significantly improve the accuracy and timeliness of predicting IOH, thereby enhancing patient safety during surgery and postoperative recovery. This research is expected to inform clinical practices related to preventative warming strategies, ultimately improving patient outcomes in gynecological laparoscopic surgery.",[97,26,98],"Laparoscopic Surgery","Gynecological Surgery",[100,71,101,102],"Laparoscopic surgery","Machine learning","Gynecology","NOT_YET_RECRUITING","2026-01-18",{"date":106,"type":41},"2026-01-20",{"date":108,"type":21},"2026-03-01",{"date":110,"type":21},"2026-07-01",{"name":112,"class":48},"Chengdu Jinjiang Maternity and Child Health Hospital",4]
