简要总结
Hypothermia occurs frequently during general anesthesia. This study is to evaluate the efficacy of 10 minutes of prewarming during induction of general anesthesia during urologic surgery.
详细描述
Hypothermia is of continuous issue in patients undergoing general anesthesia. During urologic operation (transurethral resection of bladder and prostate), bladder irrigation worsens hypothermia. Hence, various methods including prewarming of the patient are used to maintain core temperature during operation.
Prewarming is found to be effective in maintaining core temperature perioperatively by increasing peripheral tissue heat content. However, applying more than 30 minutes of prewarming may be impractical as a clinical routine practice. Hence, developing simple and effective method to prevent hypothermia is expected.
Here, the investigators planned to examine the effect of active warming (10 minutes of warming during induction of general anesthesia and prewarmed intravenous fluid intraoperatively) on hypothermia in patients undergoing urologic operation under general anesthesia.
