【摘要】：目的观察术中保温对老年患者全麻BIS恢复时间及苏醒期丙泊酚效应室浓度(Ce)的影响。方法选择60岁以上全麻下行开腹胃肠外科手术患者44例,随机分为保温组和对照组,每组22例。术中保温组采用输入液体、腹腔冲洗液体加温以及暖风毯覆盖等保温措施;对照组采用室温液体输入与铺巾覆盖。记录麻醉开始时(T0)、麻醉后30 min(T1)、60 min(T2)、90 min(T3)、120min(T4)、150min(T5)、术毕(T6)的食管温度和MAP。记录停药到BIS≥80的恢复时间、BIS≥80时丙泊酚Ce。结果T2~T6时对照组食管温度明显低于保温组(P0.05)。不同时点两组MAP差异无统计学意义。保温组患者停药到BIS≥80的恢复时间明显短于对照组,Ce明显高于对照组(P0.05)。结论低体温会延长老年患者BIS恢复时间,影响丙泊酚Ce的降低,术中保温有利于防止此类现象发生。
[Abstract]:Objective to observe the effect of intraoperative heat preservation on BIS recovery time and propofol effect chamber concentration (Ce) during general anesthesia in elderly patients. Methods 44 patients over 60 years old undergoing open gastrointestinal surgery were randomly divided into heat preservation group and control group with 22 cases in each group. The patients in the intraoperative heat preservation group were treated with liquid input, liquid heating and warm air blanket coverage, while the control group were covered with liquid at room temperature. The esophageal temperature and MAP. were recorded at the beginning of anesthesia (T 0), 30 min (T 1), 60 min (T 2), 90 min (T 3), 150 min (T 5), 30 min (T 6) after anesthesia. The recovery time of propofol Ce. with BIS 鈮，
