Inadvertent perioperative hypothermia, a common occurrence in the operating suite, is associated with many adverse outcomes. It is the nurse anesthetist's goal to attenuate the incidence of this problem. Although active intraoperative warming is a widely accepted practice, active preoperative warming may be a less explored option for temperature maintenance. A search strategy to identify systematic reviews and investigations in peer-reviewed journals was undertaken to identify evidence examining the efficacy of preoperative warming. Evidence sources meeting the search criteria were randomized controlled trials and a cohort study using historical controls. Most of the studies support the implementation of active preoperative warming by demonstrating that subjects were warmer during the perioperative period. Overall, these differences were statistically significant and likely clinically significant. Future clinical trials should examine shorter warming times and lower warming unit settings, should include appropriate sample sizes, and should consistently employ trained staff using calibrated biometric instruments to measure temperature.
围手术期意外低温在手术室中很常见，与许多不良后果相关。减轻这一问题的发生率是麻醉护士的目标。虽然术中主动升温是一种广泛接受的做法，但术前主动升温可能是一个较少探索的体温维持选项。我们采用了一种检索策略，以识别同行评审期刊中的系统评价和调查，以确定检验术前升温效果的证据。符合检索标准的证据来源是随机对照试验和一项使用历史对照的队列研究。大多数研究通过证明受试者在围手术期体温更高，支持实施术前主动升温。总体而言，这些差异具有统计学意义，可能也具有临床意义。未来的临床试验应研究更短的升温时间和更低的升温设备设置，应包括适当的样本量，并应始终由经过培训的工作人员使用校准的生物测量仪器来测量体温。
