Reduce postoperative hypothermia by up to 50% over a 12-month period in children's hospital NICUs and identify specific clinical practices that impact success.
Literature review, expert opinion, and benchmarking were used to develop clinical practice recommendations for maintaining perioperative euthermia that included the following: established euthermia before transport to the operating room (OR), standardized practice for maintaining euthermia on transport to and from the OR, and standardized practice to prevent intraoperative heat loss. Process measures were focused on maintaining euthermia during these time points. The outcome measure was the proportion of patients with postoperative hypothermia (temperature ≤36°C within 30 minutes of a return to the NICU or at the completion of a procedure in the NICU). Balancing measures were the proportion of patients with postoperative temperature >38°C or the presence of thermal burns. Multivariable logistic regression was used to identify key practices that improved outcome.
Postoperative hypothermia decreased by 48%, from a baseline of 20.3% (January 2011 to September 2013) to 10.5% by June 2015. Strategies associated with decreased hypothermia include >90% compliance with patient euthermia (36.1-37.9°C) at times of OR arrival (odds ratio: 0.58; 95% confidence interval [CI]: 0.43-0.79; < .001) and OR departure (odds ratio: 0.0.73; 95% CI: 0.56-0.95; = .017) and prewarming the OR ambient temperature to >74°F (odds ratio: 0.78; 95% CI: 0.62-0.999; = .05). Hyperthermia increased from a baseline of 1.1% to 2.2% during the project. No thermal burns were reported.
Reducing postoperative hypothermia is possible. Key practices include prewarming the OR and compliance with strategies to maintain euthermia at select time points throughout the perioperative period.
在儿童医院新生儿重症监护病房(NICU)将术后低体温减少多达 50%,并确定影响成功的具体临床实践。
文献回顾、专家意见和基准测试用于制定维持围手术期体温正常的临床实践建议,其中包括:在转运至手术室(OR)前建立体温正常、标准化实践以维持在 OR 往返途中的体温正常以及标准化实践以防止术中热量流失。过程措施侧重于在这些时间点维持体温正常。结果测量是术后低体温(返回 NICU 后 30 分钟内或在 NICU 内完成手术时体温≤36°C)的患者比例。平衡措施是术后体温>38°C 或存在热烧伤的患者比例。多变量逻辑回归用于确定改善结果的关键实践。
术后低体温率从基线的 20.3%(2011 年 1 月至 2013 年 9 月)下降至 2015 年 6 月的 10.5%,下降了 48%。与低体温减少相关的策略包括在 OR 到达时(优势比:0.58;95%置信区间[CI]:0.43-0.79;<0.001)和 OR 离开时(优势比:0.0.73;95% CI:0.56-0.95;=0.017)有超过 90%的患者体温处于 36.1-37.9°C 之间以及将 OR 环境温度预热至>74°F(优势比:0.78;95% CI:0.62-0.999;=0.05)。在项目期间,体温过高从基线的 1.1%增加到 2.2%。未报告热烧伤。
降低术后低体温是可能的。关键实践包括预热 OR 和遵守在围手术期特定时间点维持体温正常的策略。
