简要总结
This study examined whether 20 minutes of prewarming prior to gynecological laparoscopic surgery prevented inadvertent post-operative hypothermia. Treatment group received prewarming using a forced air body warming, control group received no active warming system. Both groups were then warmed with forced air warmer intraoperatively.
详细描述
Inadvertent perioperative hypothermia is a well known perioperative complication. The behavioural response to hypothermia is the most powerful protective tool, more effective than any autonomic response, and is obviously removed in the operative setting. Anesthesia alters thermoregulation by profoundly changing the thresholds for vasoconstriction and shivering, making patients vulnerable to the adverse outcomes related to mild hypothermia. Inadvertent postoperative hypothermia can occur in up to 70% of surgical patients. It is defined as a core temperature below 36°C (96.8°F). The aim of this study was to determine if prewarming with an active warming system for 20 minutes preoperatively could prevent postoperative inadvertent hypothermia.

研究组 & 干预措施
Prewarming group
Prewarmed for 20 minutes prior to OR using 3M Bair Paws System, a forced air warming blanket. This warming blanket was then used intraoperatively throughout the case.
干预措施: 3M Bair Paws Warming System (Device)
Control group
Patients received standard care, which is no active prewarming prior to OR. A full body, forced air warming blanket (same as treatment group) was used intraoperatively throughout the case.
结局指标
主要结局
Oral temperature immediately postoperatively
时间窗: Immediately post-operatively
Immediate postoperative oral temperature on admission to the post-anesthetic care unit.
次要结局
- Oral temperature at discharge from post-anesthetic care unit(Discharge from post-anesthetic care unit (average 99 minutes))
- 11-point Pain score(30 min after admission to post-anesthetic care unit)
- Oral temperature 30 minutes postoperatively(30 min after admission to post-anesthetic care unit)
