全身麻醉术后寒战相关危险因素的研究

目的研究全身麻醉术后寒战发生的相关危险因素。方法 2011例静吸复合全麻术后回麻醉后恢复室(PACU)的患者,按有无寒战发生分为寒战组(115例)和非寒战组(1896例),记录中心体温(鼻咽温度)、拔管后疼痛评分、术中出血量、手术时间。结果两组间年龄、中心体温、拔管后疼痛评分、手术时间、术中出血量差异有统计学意义(P0.01),且与寒战发生相关。结论年轻患者、中心体温下降、术后疼痛、手术时间长、术中大量出血均可增加全身麻醉术后寒战发生率。

Analysis of risk factors for postoperative shivering

Objective To investigate the risk factors for postoperative shivering.Methods A total of 2 011 patients undergoing inhalation and intravenous general anesthesia in postanesthesia care unit (PACU) after surgeries were devided into shivering group and non-shivering group.Nasopharyngeal temperature was monitored.Operative time and intraoperative hemorrhage were recorded.Results There were significant differences in age,core temperature,pain score,operative time and blood loss between two groups.These factors were positively correlated with postoperative shivering.Conclusion Younger patients,lower core temperature,higher pain scores,longer operative time and intraoperative massive hemorrhage increase the incidence of postoperative shivering.
