简要总结
Previous research has shown beneficial effects of prewarming on preventing inadvertent perioperative hypothermia (IPH). Warming the surface of the body before the induction of anesthesia can reduce the temperature difference between the core and periphery, thereby reducing the degree of core-to-peripheral thermal redistribution. It has been proved that initiation of warming before surgery can be more useful for preventing IPH than warming only during surgery. Nevertheless, there are not many researches on effects of short period (<30 min) prewarming, especially in gynecologic laparoscopic surgery. Accordingly, the investigators designed this study to test if IPH can be effectively prevented when 10 minutes of prewarming is added to intraoperative active warming in patients undergoing gynecologic laparoscopic surgery.

结局指标
主要结局
the incidence of intraoperative hypothermia
时间窗: on arrival at operating theater, before anesthesia induced, every 15 minutes after anesthetic induction until admission to the post anesthetic care unit (PACU)
Number of Participants whose core temperature was than 36℃ was recorded at each time point.
次要结局
- the incidence of postoperative shivering(on the admission to PACU, 30 minutes after the admission to PACU)
- Time-temperature interaction during the first 1 hour of anesthesia(Core body temperature was recorded at 15-min intervals from initiation of anesthesia for 1 hour.)
