目的 测定新生儿Tosight喉镜气管插管时七氟醚吸入的半数肺泡气浓度(minimum alveolar concentrations effective inhaled concentrations in 50％,MAC EI50)和95％有效肺泡气浓度(minimum alveolar concentrations effective inhaled concentrations in 95％,MAC EI95).方法 选择22例美国麻醉医师协会(American Society of Anesthesiologists,ASA)Ⅰ或Ⅱ级择期全身麻醉手术的新生儿,吸入七氟醚麻醉,初次浓度设置为3.3％,相邻浓度比为1.1,七氟醚的浓度按改良序贯法增加或减少一级,待七氟醚的浓度达血-脑平衡10 min后行气管插管.用概率单位回归法计算出新生儿Tosight喉镜气管插管时七氟醚吸入诱导的肺泡气浓度MAC EI50和E195及相应的95％可信区间(confidence interval,95％ CI).结果 全凭七氟醚吸入诱导Tosight喉镜气管插管时患儿肺泡气浓度的MAC EI50为3.65％,95％ CI为3.28％ ～ 4.04％;MAC EI95为4.24％,95％ CI为3.93％～7.14％.结论 Tosight喉镜用于新生儿气管插管时的肺泡气浓度的MAC EI50和EI95分别为3.65％和4.24％.
目的 測定新生兒Tosight喉鏡氣管插管時七氟醚吸入的半數肺泡氣濃度(minimum alveolar concentrations effective inhaled concentrations in 50％,MAC EI50)和95％有效肺泡氣濃度(minimum alveolar concentrations effective inhaled concentrations in 95％,MAC EI95).方法 選擇22例美國痳醉醫師協會(American Society of Anesthesiologists,ASA)Ⅰ或Ⅱ級擇期全身痳醉手術的新生兒,吸入七氟醚痳醉,初次濃度設置為3.3％,相鄰濃度比為1.1,七氟醚的濃度按改良序貫法增加或減少一級,待七氟醚的濃度達血-腦平衡10 min後行氣管插管.用概率單位迴歸法計算齣新生兒Tosight喉鏡氣管插管時七氟醚吸入誘導的肺泡氣濃度MAC EI50和E195及相應的95％可信區間(confidence interval,95％ CI).結果 全憑七氟醚吸入誘導Tosight喉鏡氣管插管時患兒肺泡氣濃度的MAC EI50為3.65％,95％ CI為3.28％ ～ 4.04％;MAC EI95為4.24％,95％ CI為3.93％～7.14％.結論 Tosight喉鏡用于新生兒氣管插管時的肺泡氣濃度的MAC EI50和EI95分彆為3.65％和4.24％.
