Abstract

OBJECTIVE

To determine the effect of birth order on respiratory distress syndrome (RDS) in the outcome of twins in a large premature population managed in a modern neonatal intensive care unit.

METHODS

An historical cohort study design was used to analyse the neonatal outcomes of 301 premature liveborn twin sibling pairs of between 23 and 31 weeks gestation from the Australia and New Zealand Neonatal Network 1995 database.

RESULTS

Among the 56 twin sibling pairs who were discordant for RDS, the second twin was affected in 41 cases (odds ratio (OR) 2.7, 95% confidence interval (CI) 1.5 to 5.3). The excess risk of RDS in the second twin increased with gestation and was statistically significant for twins above 29 weeks gestation (OR 4.4, 95% CI 1.6 to 15).

CONCLUSIONS

There is a significant increased risk of RDS associated with being the second born of premature twins, which appears to depend on gestation.

摘要

目的

在现代新生儿重症监护病房管理的大量早产人群中,确定出生顺序对双胎结局中呼吸窘迫综合征(RDS)的影响。

方法

采用历史性队列研究设计,分析来自澳大利亚和新西兰新生儿网络1995年数据库中301对孕23至31周的早产活产双胞胎同胞对的新生儿结局。

结果

在56对RDS情况不一致的双胞胎同胞对中,41例第二胎受影响(比值比(OR)2.7,95%置信区间(CI)1.5至5.3)。第二胎患RDS的额外风险随孕周增加,对于孕周大于29周的双胞胎具有统计学意义(OR 4.4,95%CI 1.6至15)。

结论

早产双胞胎中第二胎患RDS的风险显著增加,这似乎取决于孕周。
