The perioperative period is a time of thermal instability for older surgical patients. Beyond the elder persons vulnerability to intraoperative heat loss and hypothermia, the surgical procedure initiates host responses that affect body temperature. Technology and drug therapies often deliberately or inadvertently alter thermal balance. Alterations range from mild hypothermia to shaking febrile chills. A reasoned approach to preventing or caring for each of these alterations is based on an understanding of the dynamics of heat loss or heat gain. Early recognition of problems and appropriate action by perioperative nurses may forestall more serious consequences.
围手术期对于老年手术患者来说是一个体温不稳定的时期。除了老年人易受术中热量散失和体温过低影响外，手术过程还会引发影响体温的机体反应。技术和药物治疗常常有意或无意地改变热平衡。这些改变范围从轻度体温过低到寒战发热。预防或处理这些改变的合理方法基于对热量散失或增加动态过程的理解。围手术期护士对问题的早期识别和恰当行动可能会避免更严重的后果。
