To determine whether the covering of healthy children during anesthetic induction reduces hypothermia at the end of minor surgeries.
Randomized, single-blinded, prospective study.
Operating room and postoperative recovery area of a university-affiliated hospital.
50 ASA physical status 1 patients, aged 6 months to 3.5 years, scheduled for simple urological surgeries.
Subjects were randomly assigned to one of two groups: covered or uncovered. Children in the covered group (Group C) were actively warmed on arrival in the operating room (OR) using cotton blankets and a warm forced-air blanket set at 43°C. Children in the uncovered group (Group U) remained uncovered during the induction of general anesthesia. Children in both groups were actively warmed following placement of surgical drapes.
Temperature (in Celsius) during the study procedure was recorded for each patient.
Mean core body temperature at the end of induction did not differ in the two groups, 36.4°C in Group C and 36.6°C in Group U. Mean core body temperature at the end of surgery did not differ between the two groups: 36.9°C in Group C and 37.0°C in Group U.
Leaving healthy children uncovered during induction of general anesthesia does not have a clinically significant effect on core temperature at the end of induction or of surgery.
确定在小儿短小手术麻醉诱导期间覆盖健康儿童是否能减少手术结束时的低体温。
随机、单盲、前瞻性研究。
大学附属医院的手术室和术后恢复区。
50 例 ASA Ⅰ级健康儿童，年龄 6 个月至 3.5 岁，计划行简单的泌尿科手术。
将患者随机分为两组：覆盖组和未覆盖组。覆盖组（C 组）患儿在进入手术室时使用棉毯和设定在 43°C 的热空气毯积极升温。未覆盖组（U 组）患儿在全身麻醉诱导期间不覆盖。两组患儿在放置手术布单后均积极升温。
记录每位患者在研究过程中的体温（摄氏度）。
两组患儿诱导结束时的核心体温均值无差异，C 组为 36.4°C，U 组为 36.6°C。两组患儿手术结束时的核心体温均值无差异：C 组为 36.9°C，U 组为 37.0°C。
在全身麻醉诱导期间让健康儿童不覆盖并不会对诱导结束时或手术结束时的核心体温产生临床显著影响。
