Abstract: Objective To explore the influencing factors of hypothermia in patients undergoing da Vinci robotic surgery in urology department. Methods A retrospective analysis was conducted on 90 patients who underwent da Vinci robot assisted surgery in the urology department of our hospital from December 2020 to December 2023．According to whether hypothermia occurred during surgery,patients were divided into a hypothermia group（n=30）and a non hypothermia group（n=60）,and their basic data,preoperative related basic indicators,and perioperative related data were compared．A logistics regression model was used to analyze the influencing factors of hypothermia in patients undergoing da Vinci robotic surgery．Results There were no significant differences in gender,disease type,and ASA grading between the hypothermia group and the non hypothermia group． The age of the hypothermia group was higher than that of the non hypothermia group,and the body mass index was lower than that of the non hypothermia group（P<0.05）．There was no significant difference in preoperative hemoglobin,diastolic blood pressure,systolic blood pressure,low-density lipoprotein,high-density lipoprotein,total cholesterol,triglycerides,fasting blood glucose,and creatinine between the hypothermia group and the non hypothermia group．The preoperative albumin level in the hypothermia group was lower than that in the non hypothermia group（P<0.05）．There was no significant difference in anesthesia method,pneumoperitoneum time,temperature at entry,mean arterial pressure at entry,and intraoperative blood loss between the hypothermia group and the non hypothermia group．The total anesthesia time,surgical time,heart rate at entry,and intraoperative infusion volume were higher in the hypothermia group than in the non hypothermia group,and the duration of intraoperative insulation measures was lower in the hypothermia group than in the non hypothermia group（P<0.05）．Preoperative albumin,total anesthesia time,surgery time,intraoperative infusion volume,and duration of intraoperative insulation measures were independent influencing factors of intraoperative hypothermia in patients undergoing da Vinci robotic surgery（P<0.05）．Conclusions The occurrence of hypothermia in patients undergoing da Vinci robotic surgery in urology may be affected by preoperative albumin levels,total anesthesia time,surgery time,intraoperative infusion volume,and duration of intraoperative insulation measures．Therefore,it is necessary to increase nursing evaluation for high-risk patients with hypothermia during surgery and develop targeted intervention measures to prevent the occurrence of hypothermia in patients．
