We studied 30 adult patients of both sexes who were scheduled for abdominal surgery involving laparotomy. After three patients were excluded because surgery was unfeasible, the remaining 27 were allocated randomly to a control group (n = 14) or a group (n = 13) to be warmed by a Bair Hugger (Augustine Medical Inc.) heater. Esophageal temperature was checked every 30 min by one probe of a modular thermometric channel (Mon-a-therm) 6510 Mallincrodt, while ambient temperature was monitored by the second probe.
Significant differences in esophageal temperature were observed between the two groups from the second hour after start of surgery, and the differences increased over time. Differences were observed at the end of surgery (Bair group: 36.4 +/- 0.5 degrees C; control group: 34.7 +/- 1.1 degrees C) and upon admission to the intensive care recovery unit (Biar group: 36.3 +/- 0.6 degrees C; control 34.8 +/- 1.0 degrees C) (p < 0.0001).
The Bair Hugger heater is effective during abdominal operations lasting two or more hours. The device not only prevented hypothermia from deepening during surgery, but also reversed hypothermia in spite of being used after anesthetic induction and in spite of the loss of heat produced by secondary vasodilation.
1）量化强制空气加温在成人全身麻醉期间维持体温的效果，以及2）研究手术持续时间与所用设备提供的热保护水平之间的关系。
我们研究了30例计划进行剖腹腹部手术的成年男女患者。3例患者因手术不可行被排除后，其余27例随机分为对照组（n = 14）或使用Bair Hugger（奥古斯汀医疗公司）加热器加温的组（n = 13）。通过Mallincrodt 6510模块化测温通道（Mon-a-therm）的一个探头每30分钟检查一次食管温度，同时用第二个探头监测环境温度。
手术开始后第二小时起，两组食管温度出现显著差异，且差异随时间增加。手术结束时（Bair组：36.4±0.5℃；对照组：34.7±1.1℃）以及进入重症监护恢复病房时（Bair组：36.3±0.6℃；对照组：34.8±1.0℃）均观察到差异（p < 0.0001）。
Bair Hugger加热器在持续两小时或更长时间的腹部手术中有效。该设备不仅在手术期间防止体温过低加深，而且尽管在麻醉诱导后使用且存在继发血管扩张导致的热量散失，仍能逆转体温过低。
