摘要 目的分析合并先天性心脏病唐氏综合征患儿采用七氟烷吸入麻醉诱导的效果和安全性。方法选择33例先天性心脏病合并唐氏综合征患儿为研究对象(A组);另选35例非唐氏综合征的先天性心脏病患儿为对照(B组)。患儿美国麻醉医师学会(ASA)分级Ⅱ-Ⅲ级,年龄10个月至2岁,体质量8.0-12.5kg,两组患儿均予吸入8%七氟烷诱导,待其入睡后开放外周静脉输注复方电解质注射液。所有患儿手控呼吸待电脑双频谱指数低于40后行气管插管,并予吸入七氟烷-空氧混合(1∶1)气体和连续输注舒芬太尼2.5μg·kg^-1·h^-1式阿曲库铵100μg·kg^-1·h^-1麻醉。分别记录两组患儿在麻醉前(T1)、气管插管时(T2)和气管插管后5min(T3)、10min(T4)和20min(T5)时间点的心率(HR)、血氧饱和度(SpO2)、收缩压(SBP)、舒张压(DBP)及可能的不良反应。结果七氟烷吸入麻醉诱导后组内比较患儿的SBP、DBP和HR均较基础值有所下降(P〈0.05)。组间比较两组患儿的生命体征,A组患儿麻醉后T3和T4时间点心率与对照组比较,差异有统计学意义(P〈0.05)。比较两组患儿麻醉后生命体征所达最小值与基础状态间的差值,A组患儿HR下降较对照组更为明显(P〈0.05)。组间和组内比较患儿麻醉前后SpO2比较,差异无统计学意义(P〉0.05)。有9例A组患儿(27.3%)和2例B组患儿(5.7%)发生严重心动过缓,A组中7例患儿和B组中1例患儿需静脉注射阿托品后才得以缓解,差异均有统计学意义(P〈0.05)。结论合并先天性心脏病的唐氏综合征患儿经七氟烷吸入麻醉诱导后较普通先天性心脏病患儿容易发生心动过缓,部分患儿需要进行药物干预。
