【摘要】:目的:探究在全凭吸入七氟醚全身麻醉诱导下,汉族与维吾尔族妇科患者顺利置入喉罩时的七氟醚最低肺泡有效浓度。方法:选取汉族与维吾尔族各30例年龄20~50岁,美国麻醉医师协会(ASA)Ⅰ或Ⅱ级,择期在腹腔镜下卵巢囊肿剔除术的患者。采用序贯法进行实验,第1例患者的起始浓度为2.0%,浓度间隔设定为0.2%。吸入8%七氟醚高浓度诱导,睫毛反射消失后调整吸入七氟醚的浓度以达到呼气末浓度的预定值,维持这个预定值10min后为患者置入喉罩。置入喉罩即刻以及置入喉罩后的1min内患者如果出现咳嗽、肢体运动、下颌松弛困难以致喉罩无法插入,屏气、喉痉挛、低氧血症这其中的任何一项即认为置入喉罩不满意。若上一例效果满意,则下一例采用低一级浓度;若不满意,则下一例采用高一级的浓度。采用Probit概率单位回归法计算满足喉罩顺利置入的半数有效量(EC50)和95%有效量(EC95)以及各自的95%的可信区间(95%Cl)。结果:在全凭吸入七氟醚全身麻醉诱导下,汉族妇科患者顺利置入喉罩时的七氟醚ECso为1.94%,95%CI为1.79%-2.07%,EC95为2.36%,95%CI为2.12%-4.15%;维吾尔族患者七氟醚EC50为2.06%,95%CI为1.92%-2.20%,EC95为2.65%,95%CI为2.20%-4.55%。维吾尔族患者七氟醚最低有效浓度高于汉族,P0.05。结论:95%的妇科患者全凭吸入七氟醚可满意置入喉罩的最低有效浓度(EC95)汉族为2.36%,维吾尔族为2.65%。
