Sixty patients (47 female) undergoing surgical excision of three or more wisdom teeth were randomly allocated into three groups with differing end-tidal carbon dioxide and volatile agent concentrations during maintenance of anaesthesia. The anaesthetic techniques employed were identical in all other respects. All patients were observed for 10 min after arrival in the recovery area to assess the presence and severity of shivering, axillary temperature and oxygen saturation. There were no significant differences in axillary temperatures between groups or between shivering and non-shivering patients, although there was a significant difference (p = 0.001) in duration of anaesthesia between shivering and non-shivering patients. There was no significant difference between groups with respect to the incidence of shivering (p = 0.96).
60例（47例女性）接受三颗或更多智齿手术切除的患者在麻醉维持期间被随机分为三组，三组的呼气末二氧化碳和挥发性麻醉剂浓度不同。在所有其他方面，所采用的麻醉技术是相同的。所有患者在进入恢复区后观察10分钟，以评估寒战的存在和严重程度、腋窝温度和氧饱和度。尽管寒战患者和非寒战患者之间的麻醉持续时间存在显著差异（p = 0.001），但三组之间以及寒战患者和非寒战患者之间的腋窝温度均无显著差异。寒战发生率在各组之间无显著差异（p = 0.96）。
