To determine gestational age-specific neonatal outcomes of late preterm infants delivered as a consequence of premature rupture of membranes (PROM).
Retrospective cohort study of infants born to women delivered electively due to preterm PROM between 34(0/7) and 36(6/7) weeks of gestation. Neonatal outcomes were compared between those delivered at 34(0/7) to 34( 6/7) weeks, at 35(0/7) to 35(6/7) weeks, and at 36( 0/7) to 36(6/7) weeks.
192 infants were identified. The 34(0/7) to 34(6/7) week infants had significantly higher neonatal intensive care admission rate (72.5%) compared to those at 35( 0/7) to 35(6/7) weeks (22.8%) and at 36 to 36(6/7) weeks (17.8%) (P < .05). Neonatal respiratory distress syndrome was significantly higher at 34(0/7) to 34(6/7) weeks (35.4%) compared with 35(0/7) to 35(6/7) week and 36(0/7) to 36( 6/7) week infants (10.5% and 4.1%; P < .05). The longest hospitalization occurred in the 34(0/7) to 34(6/7) week infants (248.5 +/- 20.0 hours).
Substantial short-term morbidity occurred in late preterm infants. The greatest number of complications affected infants born at 34(0/7) to 34(6/7) weeks.
确定因胎膜早破（PROM）而分娩的晚期早产儿的孕周特异性新生儿结局。
对因早产PROM在妊娠34(0/7)至36(6/7)周期间择期分娩的妇女所生婴儿进行回顾性队列研究。比较在34(0/7)至34(6/7)周、35(0/7)至35(6/7)周以及36(0/7)至36(6/7)周分娩的婴儿的新生儿结局。
共识别出192例婴儿。与35(0/7)至35(6/7)周（22.8%）和36至36(6/7)周（17.8%）分娩的婴儿相比，34(0/7)至34(6/7)周分娩的婴儿新生儿重症监护病房入院率显著更高（72.5%）（P <.05）。34(0/7)至34(6/7)周分娩的婴儿新生儿呼吸窘迫综合征发生率显著高于35(0/7)至35(6/7)周以及36(0/7)至36(6/7)周分娩的婴儿（分别为35.4%、10.5%和4.1%；P <.05）。住院时间最长的是34(0/7)至34(6/7)周分娩的婴儿（248.5 +/- 20.0小时）。
晚期早产儿出现大量短期发病情况。并发症数量最多的是在34(0/7)至34(6/7)周出生的婴儿。
