术中保温对低体温创伤患者麻醉恢复期的影响

Effects of Warming on Postanesthesia Recovery Period of Hypothermic Trauma Patients during Surgery

目的观察保温对低体温创伤手术患者麻醉恢复期的影响。方法选择创伤严重度评分介于16~40分之间,且肛温〈36℃需进行手术的创伤患者80例,随机分为保温组和对照组,每组40例。两组均在室温下手术,保温组采用各种措施保持肛温≥36℃,对照组体温未施加干预。记录两组气管拔管时间、苏醒时间、心律失常、寒战及躁动的发生情况。结果与对照组比较,保温组气管拔管时间、苏醒时间缩短（P〈0.01）,心律失常、寒战及躁动的发生率低（P〈0.05）。结论术中采取保温措施可以明显缩短低体温创伤患者麻醉恢复期,减少各种并发症的发生,使患者平稳度过麻醉恢复期。

Objective To investigate the effects of temperature intervention on postanesthesia recovery period of hypothermic trauma patients in the period of surgical procedures.Methods 80 cases undergoing operation with ISS score between 16～40 and rectal temperature below 36℃ were randomly divided into control group（n=40） and warming group（n=40）.All patients were under room temperature during surgery.In the warming group,the patients＇ rectal temperature was maintained above 36℃ by various kinds measures,while patients in the control group without any temperature intervention.BP、HR were monitored before and after surgery.The extubate time,awaking time,heart arrhythmia,shiver and restless movementwere recorded after operation.Results Compared with the control group,BP was lower,HR was slower,the extubate time、awaking time were shorten significantly in the warming group（P0.01）.The incidence of heart arrhythmia,shiver and restless movement were also markedly higher in the control group（P0.05）.Conclusion Intraoperative warming can help to shorten the postanesthesia recovery period,decrease complication in the hypothermic trauma patients.
