Background & Problems: Hypothermia is the cause of multiple problems such as delayed awaking from anesthesia, feelings of discomfort, increased oxygen consumption, and increased risks of surgical wound infection and complications. A review of the record of post-operative patients receiving general anesthesia (GA) revealed that only 74% of the patients in our post-anesthesia room (PAR) had restored their body temperature to 36℃ after 60 minutes. Through situation analysis, several causes were identified, including insufficient warming facilities, lack of standard procedures and an audit system, lack of knowledge regarding hyperthermia among nurses, and the incompleteness of perioperative warming interventions performed by the healthcare team. Purpose: The aim of the present project was to apply team resource management (TRM) to raise the rate of body temperature restoration to 36℃ after 60 minutes in our post-anesthesia room (PAR) from 74% to 100%. Resolution: Several strategies were implemented to accelerate the post-operative rewarming for patients receiving GA, including: establishment of standard operating procedures for warming, conducting routine audits, purchasing warming facilities, conducting in-service education, applying TRM, and cooperating with nurses in operating rooms on executing the warming plan. Result: After implementing these strategies, our PAR achieved a 100% success rate in raising the body temperature of postoperative patients to 36℃ after 60 minutes. Conclusions: The result demonstrates that hypothermia may be effectively avoided and that the quality of postoperative care may be effectively improved through transdisciplinary teamwork.
