Abstract
BackgroundThis study explored the comparison of the thermal insulation effect of incubator to infusion thermometer in laparoscopic hysterectomy.MethodsWe 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.ResultsThe 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).ConclusionWarming 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.Trial registrationThis trial was registered with ChiCTR2000039162, 20 October 2020.

Summary
This study explored the comparison of the thermal insulation effect of incubator to infusion thermometer in laparoscopic hysterectomy. Reports describe perioperative hypothermia as a condition whereby the core body temperature drops below 36 °C [1]. Its incidence rate ranges between 25 and 90% [2]. Perioperative hypothermia is associated with a range of complications, such as intraoperative coagulation dysfunction, delayed postoperative recovery, incision infection, among others [3, 4]. Laparoscopic surgery presents benefits, including less trauma, less bleeding, more rapid postoperative recovery, fewer surgical complications, etc. Our main focus was to compare the effects of two different thermal insulation methods in laparoscopic hysterectomy The abdominal cavity is relatively more closed, anesthetic factors, persistent C02 pneumoperitoneum during surgery, and the utilization of huge amounts of irrigating fluid may induce hypothermia [7, 8].
