Abstract

OBJECTIVE

To examine immediate neonatal outcomes associated with elective labor induction.

STUDY DESIGN

Labor inductions occurring at > or = 38 weeks' gestation were examined during a 6-month period at 2 community hospitals. Medical records were reviewed by trained abstractors to determine the reason for induction (elective vs. medical) and maternal characteristics. The need for newborn resuscitation (1-minute Apgar score < 4) was the primary end point. Multiple logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

Of the 364 inductions, 54.9% were elective. The odds of a 1-minute Apgar score being < or = 3 were significantly greater when labor was induced for elective reasons than for medical reasons (OR 5.5, 95% CI 1.1-27.9) or was spontaneous (OR 6.5, 95% CI 2.4-17.8), after controlling for mother's age, race and route of delivery. Elective induction was not associated with feal intolerance to labor, a low 5-minute Apgar score or need for admission to a special care nursery.

CONCLUSION

An elective abortion induction is an independent risk factor for delivery of an infant requiring immediate attention.

摘要

目的

研究与择期引产相关的新生儿即时结局。

研究设计

在两家社区医院对孕周≥38周时进行的引产进行为期6个月的研究。由经过培训的摘要撰写人员查阅病历，以确定引产原因（择期与医疗原因）及产妇特征。新生儿复苏需求（1分钟阿氏评分<4）为主要终点。采用多因素logistic回归计算比值比（OR）及95%置信区间（CI）。

结果

在364例引产中，54.9%为择期引产。在控制产妇年龄、种族及分娩方式后，因择期原因引产时1分钟阿氏评分≤3的几率显著高于因医疗原因引产（OR 5.5，95%CI 1.1 - 27.9）或自然分娩（OR 6.5，95%CI 2.4 - 17.8）。择期引产与胎儿对分娩不耐受、5分钟阿氏评分低或入住特殊护理病房需求无关。
