【摘要】：目的觀察術(shù)中保溫對老年患者全麻BIS恢復(fù)時間及蘇醒期丙泊酚效應(yīng)室濃度(Ce)的影響。方法選擇60歲以上全麻下行開腹胃腸外科手術(shù)患者44例,隨機分為保溫組和對照組,每組22例。術(shù)中保溫組采用輸入液體、腹腔沖洗液體加溫以及暖風(fēng)毯覆蓋等保溫措施;對照組采用室溫液體輸入與鋪巾覆蓋。記錄麻醉開始時(T0)、麻醉后30 min(T1)、60 min(T2)、90 min(T3)、120min(T4)、150min(T5)、術(shù)畢(T6)的食管溫度和MAP。記錄停藥到BIS≥80的恢復(fù)時間、BIS≥80時丙泊酚Ce。結(jié)果T2~T6時對照組食管溫度明顯低于保溫組(P0.05)。不同時點兩組MAP差異無統(tǒng)計學(xué)意義。保溫組患者停藥到BIS≥80的恢復(fù)時間明顯短于對照組,Ce明顯高于對照組(P0.05)。結(jié)論低體溫會延長老年患者BIS恢復(fù)時間,影響丙泊酚Ce的降低,術(shù)中保溫有利于防止此類現(xiàn)象發(fā)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，
