Inadvertent perioperative hypothermia is defined as a decrease in core body temperature below 36°C (96.8°F) in patients undergoing surgery, starting from one hour before anesthesia induction in the preoperative period, during the intraoperative period, and in the postoperative period in intensive care unit, spanning 24 hours. Inadvertent perioperative hypothermia is a preventable complication that occurs during surgery and can occur due to factors, such as open skin and abdominal cavity, general or regional anesthesia, prolonged surgery duration, low ambient temperature, use of cold irrigation or intravenous fluids, and factors related to the patient. Morbid heart problems, delayed wound healing, increased blood loss and blood transfusion, surgical site infection, deterioration in drug metabolism, and prolonged intensive care and hospital stay are some of the complications that may result from hypothermia. There are several international evidence-based practice guidelines for the prevention and control of hypothermia in the perioperative period. Although the guidelines state that hypothermia can be prevented with some simple and cost-effective measures implemented during the perioperative process, the compliance rate with these practices may be poor in clinical practice. In this article, the practices of healthcare professionals in preventing inadvertent perioperative hypothermia will be discussed in line with evidence-based guidelines.
术中无意识低温是指患者在手术过程中核心体温下降至 36°C（96.8°F）以下，从术前麻醉诱导前 1 小时开始，一直持续到术后重症监护期间的 24 小时内。术中无意识低温是一种可预防的并发症，可发生于手术过程中，可能由以下因素引起：皮肤和腹腔暴露、全身或区域麻醉、手术时间延长、环境温度低、使用冷冲洗液或静脉输液、以及与患者相关的因素。低温可能导致严重的心脏问题、伤口愈合延迟、失血和输血增加、手术部位感染、药物代谢恶化以及重症监护和住院时间延长等并发症。有几项针对围手术期低温预防和控制的国际循证实践指南。尽管指南指出，通过在围手术期实施一些简单且具有成本效益的措施，可以预防低温，但这些实践在临床实践中的依从率可能较低。本文将根据循证指南讨论医护人员预防术中无意识低温的实践。
