NEJM:早产儿早期接受全身性糖皮质激素,利弊皆有

2015-10-15 崔倩 译 MedSci原创

全身性糖皮质激素减少了极度早产儿支气管肺发育不良的发生率,但它们可能会损害脑发育。吸入性糖皮质激素对这些婴儿结果的影响目前还不清楚。研究人员随机分配863名婴儿(胎龄,23周0天〜27周6天)接受早期(出生后24小时内)吸入布地奈德或安慰剂,直到他们不再需要的氧气和正压支持或直到他们达到32周0天的胎龄。主要的结果是死亡或支气管肺发育不良,通过标准化的氧饱和度监测方法在36周胎龄时进行证实。在43

全身性糖皮质激素的应用减少了极度早产儿支气管肺发育不良的发生率,但它们可能会损害脑发育。吸入性糖皮质激素对这些婴儿结果的影响目前还不清楚。

研究人员随机分配863名婴儿(胎龄,23周0天〜27周6天)接受早期(出生后24小时内)吸入布地奈德或安慰剂,直到他们不再需要氧气和正压支持或直到他们达到32周0天的胎龄。主要的结果是死亡或支气管肺发育不良,通过标准化的氧饱监测方法在36周胎龄时进行证实。

在437名被分配接受布地奈德治疗的婴儿中的175名,这些婴儿有足够的资料可查(40.0%),和被分配接受安慰剂的419名婴儿中的194名婴儿(46.3%),死亡或支气管肺发育不良(相对危险,根据胎龄分层,0.86;95%置信区间[Cl]0.75至1.00;P=0.05)。支气管肺发育不良的发生率分别为:布地奈德组27.8%,安慰剂组38.0%(相对风险,根据孕周分层,0.74;95%Cl,0.60至0.91;P=0.004);死亡率分别为16.9%和13.6%(相对风险,根据孕周分层,1.24;95%Cl,0.91至1.69;P =0.17)。布地奈德组的婴儿需要外科手术治疗动脉导管未闭的概率比安慰剂组要低(相对风险,根据孕周分层,0.55;95%Cl,0.36至0.83;P=0.004),同样需要再插管婴儿的比例在布地奈德组要低于安慰剂组(相对风险,根据孕周分层,0.58;95%Cl,0.35至0.96;P=0.03)。其他新生儿疾病和不良事件率在两个组中相似。

在极度早产儿中,接受早期吸入布地奈德的婴儿,支气管肺发育不良的发生率比那些接受安慰剂的婴儿概率较低,但是这种优势可能会使增加的死亡率的费用增多。
