Background Intraoperative hypothermia (core temperature <36.0°C) is common during the perioperative period and can result in adverse consequences, especially in children. We aimed to determine the incidence of intraoperative hypothermia and its risk factors in pediatric patients during burn surgery. Methods In the present study we enrolled 197 pediatric patients with burn injury undergoing surgical debridement and skin grafting. Factors, such as total burn surface area (TBSA), were collected and analyzed to identify the potential risk factors for intraoperative hypothermia. Results The incidence of intraoperative hypothermia among all patients was 17.8%. Compared with patients with normothermia, children with hypothermia were associated with larger TBSA (25% vs 15%, p<0.001) and with less intraoperative active warming (34.28% vs 54.93%, p<0.05). In addition, compared with patients with moderate-degree burn, patients with severe and extremely severe burn were associated with much higher risk of intraoperative hypothermia [severe: odds ratio (OR)=3.805, 95% confidence interval (CI)=1.396-10.368, p=0.009; extremely severe: OR=6.933, 95% CI=2.604-18.462, p<0.001]. TBSA was the only independent risk factor that emerged as being strongly associated with intraoperative hypothermia (OR=1.068, p=0.001) and could be used to predict the occurrence of hypothermia when combined with other factors. TBSA for predicting intraoperative hypothermia by receiver operating characteristic (ROC) curve analysis showed a good predictive ability with an area under the ROC curve of 0.758. Conclusion TBSA is an important risk factor for intraoperative hypothermia in pediatric patients with burn.

小儿烧伤手术术中低体温的危险因素研究

背景 术中体温过低（核心温度 <36.0°C）在围手术期很常见，可导致不良后果，尤其是在儿童中。我们的目的是确定烧伤手术期间儿科患者术中体温过低的发生率及其危险因素。方法 在本研究中，我们招募了 197 名接受手术清创和植皮的烧伤儿科患者。收集并分析总烧伤表面积 (TBSA) 等因素，以确定术中体温过低的潜在危险因素。结果所有患者术中低体温发生率为17.8%。与体温正常的患者相比，体温过低的儿童与较大的 TBSA（25% 对 15%，p<0.001）和较少的术中主动加温（34.28% 对 54.93%，p< 0.05）。此外，与中度烧伤患者相比，重度和极重度烧伤患者术中低体温的风险要高得多[重度：比值比（OR）=3.805，95%置信区间（CI）=1.396-10.368 , p=0.009; 极度严重：OR=6.933，95% CI=2.604-18.462，p<0.001]。TBSA 是唯一与术中体温过低密切相关的独立危险因素 (OR=1.068, p=0.001)，与其他因素结合可用于预测体温过低的发生。TBSA通过接受者操作特征（ROC）曲线分析预测术中体温过低显示出良好的预测能力，ROC曲线下面积为0.758。结论 TBSA是小儿烧伤患者术中低体温的重要危险因素。此外，与中度烧伤患者相比，重度和极重度烧伤患者术中低体温的风险要高得多[重度：比值比（OR）=3.805，95%置信区间（CI）=1.396-10.368 , p=0.009; 极度严重：OR=6.933，95% CI=2.604-18.462，p<0.001]。TBSA 是唯一与术中体温过低密切相关的独立危险因素 (OR=1.068, p=0.001)，与其他因素结合可用于预测体温过低的发生。TBSA通过接受者操作特征（ROC）曲线分析预测术中体温过低显示出良好的预测能力，ROC曲线下面积为0.758。结论 TBSA是小儿烧伤患者术中低体温的重要危险因素。此外，与中度烧伤患者相比，重度和极重度烧伤患者术中低体温的风险要高得多[重度：比值比（OR）=3.805，95%置信区间（CI）=1.396-10.368 , p=0.009; 极度严重：OR=6.933，95% CI=2.604-18.462，p<0.001]。TBSA 是唯一与术中体温过低密切相关的独立危险因素 (OR=1.068, p=0.001)，与其他因素结合可用于预测体温过低的发生。TBSA通过接受者操作特征（ROC）曲线分析预测术中体温过低显示出良好的预测能力，ROC曲线下面积为0.758。结论 TBSA是小儿烧伤患者术中低体温的重要危险因素。与中度烧伤患者相比，重度和极重度烧伤患者术中体温过低的风险要高得多 [重度：比值比 (OR)=3.805，95% 置信区间 (CI)=1.396-10.368，p= 0.009；极度严重：OR=6.933，95% CI=2.604-18.462，p<0.001]。TBSA 是唯一与术中体温过低密切相关的独立危险因素 (OR=1.068, p=0.001)，与其他因素结合可用于预测体温过低的发生。TBSA通过接受者操作特征（ROC）曲线分析预测术中体温过低显示出良好的预测能力，ROC曲线下面积为0.758。结论 TBSA是小儿烧伤患者术中低体温的重要危险因素。与中度烧伤患者相比，重度和极重度烧伤患者术中体温过低的风险要高得多 [重度：比值比 (OR)=3.805，95% 置信区间 (CI)=1.396-10.368，p= 0.009；极度严重：OR=6.933，95% CI=2.604-18.462，p<0.001]。TBSA 是唯一与术中体温过低密切相关的独立危险因素 (OR=1.068, p=0.001)，与其他因素结合可用于预测体温过低的发生。TBSA通过接受者操作特征（ROC）曲线分析预测术中体温过低显示出良好的预测能力，ROC曲线下面积为0.758。结论 TBSA是小儿烧伤患者术中低体温的重要危险因素。
