【摘要】：目的探討腦電雙頻指數(shù)(BIS)監(jiān)測對七氟醚吸入麻醉復(fù)合臂叢神經(jīng)阻滯在小兒上肢手術(shù)的指導(dǎo)意義。方法將擇期行上肢手術(shù)小兒50例,隨機(jī)分為BIS反饋調(diào)控七氟醚組(Ⅰ組)和根據(jù)經(jīng)驗用藥組(Ⅱ組),每組25例,Ⅰ組在BIS監(jiān)測下指導(dǎo)術(shù)中七氟醚吸入麻醉維持BIS在(65±5),Ⅱ組吸入七氟醚誘導(dǎo)小兒睫毛反射消失后依臨床經(jīng)驗來調(diào)節(jié)七氟醚吸入濃度。兩組小兒均于麻醉誘導(dǎo)完成后行超聲引導(dǎo)下肌間溝臂叢神經(jīng)阻滯。觀察并記錄各時間點MAP、HR、Sa O2,記錄每5min BIS值,觀察兩組小兒麻醉誘導(dǎo)時間、蘇醒時間、恢復(fù)室停留時間及七氟醚用量,追蹤觀察術(shù)后小兒家屬滿意程度。結(jié)果兩組小兒麻醉開始時T1、出恢復(fù)室時T6,MAP、HR、Sa O2、BIS,組間比較差異無統(tǒng)計學(xué)意義(P0.05),誘導(dǎo)完成時T2、神經(jīng)阻滯時T3、麻醉結(jié)束時T4、蘇醒時T5,Ⅰ組BIS值比Ⅱ組高,Ⅱ組MAP、HR變化大于Ⅰ組,差異有統(tǒng)計學(xué)意義(P0.05),麻醉誘導(dǎo)時間T1-T2、蘇醒時間T4-T5、恢復(fù)室停留時間T5-T6及七氟醚用量Ⅰ組少于Ⅱ組,差異有統(tǒng)計學(xué)意義(P0.05)。結(jié)論 BIS指導(dǎo)下七氟醚吸入麻醉復(fù)合臂叢神經(jīng)阻滯,可降低七氟醚吸入量,有助于判斷全麻深度,有利于小兒術(shù)后的恢復(fù)。
