目的探讨HIE新生儿血浆N端脑钠肽原(NT-proBNP)和血清电解质的变化,评价血浆NT-proBNP对新生儿窒息并心功能障碍的诊断价值。方法将确诊为HIE的64例患儿分为轻度组、中度组和重度组,对各组HIE患儿及41例健康新生儿(健康对照组)采用竞争性酶免疫法(EIA)检测血浆NT-proBNP,采用电解质分析仪检测其血清钾、钠、氯、钙水平。结果轻度HIE组血浆NT-proBNP[(3540±992)pmol/L]明显高于健康对照组[(3192±1486)pmol/L](t=1.908 P0.05);中度HIE组血清钠、氯、钙水平明显低于轻度组(t=2.78,2.91,3.21 Pa0.05);重度HIE组血清钠、氯、钙水平明显低于中度组(t=2.92,2.98,3.32 Pa0.05)。重度HIE组血浆NT-proBNP水平与血清钠、氯、钙水平均呈显著负相关(r=-0.762,-0.781,-0.802 Pa<0.01)。结论HIE患儿血浆NT-proBNP水平能反映其心功能损害及心肌损害的程度及疗效。联合检测HIE患儿血浆NT-proBNP和血清电解质水平对于判断病情、评价疗效和预测预后均有一定价值。
