目的 基于信息化管理平台，开发体外循环心脏术后危重患者体温信息化管理平台并探究其临床应用效果。方法 成立研究团队，通过文献回顾、小组讨论、专家函询等方法开发体外循环心脏术后危重患者体温信息化管理平台，选取2023年10月—12月在青岛市某三级甲等医院行体外循环心脏手术的患者作为研究对象，进行临床应用并评价应用效果。结果 体外循环心脏术后危重患者体温信息化管理平台应用后，患者发热率、低体温率、疼痛评分、气管插管时间较应用前显著降低（均P<0.05）；热舒适度、脑氧饱和度较应用前均有显著提升（均P<0.05）。结论 体外循环心脏术后危重患者体温信息化管理平台能够对患者体温实施精准化管理，有利于综合评估与精准干预，有效加强医护协作，促进患者术后康复。

Objective To construct a temperature information management program for critically ill patients after extracorporeal circulation heart surgery based on the information management platform，and explore its clinical application effectiveness. Methods The research team was established to construct a temperature information management program for critically ill patients after extracorporeal circulation heart surgery through literature review，group discussion，expert inquiry，and etc.，and develop the body temperature information management platform. Patients who underwent cardiopulmonary bypass cardiac surgery in a tertiary hospital in Qingdao from October to December 2023 were selected as the research subjects to carry out clinical application，and evaluate the application effects. Results After the application of the temperature information management program for critically ill patients after extracorporeal circulation heart surgery，the rate of fever，the rate of hypothermia，pain score，the length of tracheal intubation were significantly reduced compared to those before the application（P<0.05）. The thermal comfort and cerebral oxygen saturation were significantly improved compared to those before the application（P<0.05）. Conclusion The information management program of temperature for critically ill patients after extracorporeal circulation heart surgery could implement precise management of patients’ body temperature，facilitate the comprehensive assessment and precise intervention，effectively strengthen collaboration between doctors and nurses，and promote postoperative recovery of patients.
