This study explored the comparison of the thermal insulation effect of incubator to infusion thermometer in laparoscopic hysterectomy.
We assigned 75 patients enrolled in the study randomly to three groups: Group A: Used warming blanket; group B: Used warming blanket and infusion thermometer; group C: Used warming blanket and incubator. The nasopharyngeal temperature at different time points during the operation served as the primary outcome.
The nasopharyngeal temperature of the infusion heating group was significantly higher than that of the incubator group 60 min from the beginning of surgery (T3): 36.10 ± 0.20 vs 35.81 ± 0.20 (P<0.001)90 min from the beginning of surgery (T4): 36.35 ± 0.20 vs 35.85 ± 0.17 (P<0.001). Besides, the nasopharyngeal temperature of the incubator group was significantly higher compared to that of the control group 60 min from the beginning of surgery (T3): 35.81 ± 0.20 vs 35.62 ± 0.18 (P<0.001); 90 min from the beginning of surgery (T4): 35.85 ± 0.17 vs 35.60 ± 0.17 (P<0.001). Regarding the wake-up time, that of the control group was significantly higher compared to the infusion heating group: 24 ± 4 vs 21 ± 4 (P = 0.004) and the incubator group: 24 ± 4 vs 22 ± 4 (P = 0.035).
Warming blanket (38 °C) combined infusion thermometer (37 °C) provides better perioperative thermal insulation. Hospitals without an infusion thermometer can opt for an incubator as a substitute.

本研究旨在比较腹腔镜子宫切除术中保温毯与输液加温计的保温效果。
将 75 名患者随机分为三组：A 组：使用保温毯；B 组：使用保温毯和输液加温计；C 组：使用保温毯和孵化器。以手术不同时间点的鼻咽温度为主要结局。
手术开始 60 分钟时（T3），输液加热组的鼻咽温度明显高于孵化器组：36.10±0.20 vs 35.81±0.20（P<0.001）；手术开始 90 分钟时（T4）：36.35±0.20 vs 35.85±0.17（P<0.001）。此外，与对照组相比，孵化器组的鼻咽温度在手术开始 60 分钟时（T3）显著升高：35.81±0.20 vs 35.62±0.18（P<0.001）；手术开始 90 分钟时（T4）：35.85±0.17 vs 35.60±0.17（P<0.001）。至于苏醒时间，对照组明显长于输液加热组：24±4 与 21±4（P=0.004）和孵化器组：24±4 与 22±4（P=0.035）。
保温毯（38°C）联合输液加温计（37°C）提供更好的围手术期保温。没有输液加温计的医院可以选择孵化器作为替代品。
