摘要
目的评估术中浅体温对麻醉恢复延迟的影响。方法择期在异内酚复合全麻下行腹股部较大手术的患者150例,随机分为两组,试验组(NT组)76例,正常的术室温度下,手术后加用自制保暖装置,维持术中中心温度在36.5℃左右。对照组74例(LT组),在麻醉手术过程中,不施加任何体温干预措施。患者中心温度任其自然变化,试验组患者术后停用保温装置。患者转入麻醉恢复室后,每20min监测中心体温一次,采用Aldrst和Lcroulik评分系统,评价适于转出麻醉恢复室的标准,当患者至少两次评分在13分以上为转出标准。结果两组中心温度相差在2℃左右,NT组(36.7±0.6)℃,LT组为(34.8±0.6)℃,P<0.001,LT组术后符合转出评分≥13分所需时间比NT组延迟40min,LT组(94±63)min、NT组(53±36)min,P<0.001,与NT组比较,中心温度回升至36℃左右和符合转出评分≥13分所需时间多用90min,P<0.001。结论术中维持中心体温在正常水平,有利于术后麻醉恢复。
Objective To assess the effects of mild hypothermia intraoperative prolongs post- anesthetic recovery. Methods One hundred and fifty ASA Ⅰ - Ⅲ patients （74 males 76 females） aged 22 -63 yrs, undergoing elective major abdominal surgery were anesthetized with total intravenous anesthesia of propofol and fentanyl, They were randomly assigned to routine thermal management （ hypothermia） or extra warming （normothermia）. Fitness for discharge from the postanesthesia care unit was evaluated at 20min intervals by investigators blinded to group assignment and postoperative core temperatures. Scoring was based on a modification of a previously publised system that included activity. Ventilation consciousness and hemodynamic responses. Patients were considered fit for discharge when they sustained a score of 80% （13points） for at least two consecutive measurement periods. Results Final intraoperative core temperatures differed by 2℃ ; （ 34. 8 ± 0. 6 ） ℃ vs （ 36. 7 ± 0. 6 ） ℃ （P 〈0. 001 ）, Hypothermia patients required 40min longer （94 ± 63 ） min vs （53 ± 36） min to reach fitness for discharge. Duration of recovery in the two groups differed by 90min when a core temperature 〉 36℃ was also requried （P 〈 0. 001 ） . Conclusion Maintaining core normothermia decrease the duration of postanesthetic recovery.
