目的了解医源性早产的病因构成以及对母婴预后的影响。方法回顾性分析我院83例医源性早产的临床资料。结果母体因素居多,首位因素是重度子痫前期,胎儿因素为多种原因所致的胎儿窘迫。孕周>35周的早产儿并发症发生率及围生儿死亡率明显低于孕周<35周的早产儿(P<0.05)。定期的产前检查、终止妊娠前糖皮质激素的应用可降低早产儿的并发症和围生儿的死亡率。结论定期产前检查、积极治疗并发症、适时选择医源性早产对改善妊娠结局有益。

Methods The clinical data of 83 cases of iatrogenic preterm labor in our hospital were retrospectively analyzed. Results The majority of maternal factors, the first factor is severe preeclampsia, fetal factors for a variety of causes of fetal distress. Preterm infants with gestational age> 35 weeks had a significantly lower complication rate and perinatal mortality than premature infants <35 weeks of gestational age (P <0.05). Regular antenatal screening and cessation of pre-pregnancy glucocorticoid use reduce the risk of complications and perinatal mortality in preterm infants. Conclusion Regular prenatal examination, active treatment of complications, timely selection of iatrogenic preterm labor is beneficial to improve pregnancy outcome.
