Abstract: Objective To investigate the effect of elective cesarean section prenatal hormones on the full-term infants respiratory distress syndrome (RDS) incidence and complications. Methods The 2 606 cases of survival of full-term infants born in Huzhou Maternal and Child Healthcare Hospital between January,2010 to January,2011.Cases were divided into two groups:dexamethasone was used for a course more than 24 hours before the baby was born as observation group;the other group was the control group without dexamethasone.And the two groups were divided into three groups,depending on gestational age,respectively.which were gestational age 37~37⁺⁶ weeks,gestational age 38~38⁺⁶ weeks,gestational age 39~40 weeks.The different gestationgal age of the incidence of RDS and complications were compared. Result The incidence of RDS in the observation group was significantly lower than the control group,and the incidence in the different gestational was different,and the condition of the observation group was light compared with the control group.Conclusion 37~38 weeks cesarean section prenatal use of hormones is worth promoting.

摘要： 目的 探讨择期剖宫产产前使用激素对足月儿呼吸窘迫综合征(respiratory distress syndrome,RDS)发生率及并发症等的影响。 方法 以2010年1月-2011年1月在湖州妇幼保健院择期剖宫产(孕周在37~40周之间)所生足月儿2 606例为对象,根据是否使用激素分为两组,一组其母于分娩24 h前正规使用地塞米松1个疗程,该组为观察组;另一组未使用激素的足月儿为对照组;并把两组根据不同胎龄分别分为3小组,分别为37~37⁺⁶;38~38⁺⁶;39~40周组,比较不同胎龄择期剖宫产RDS发生率的高低,合并并发症情况比较。结果 观察组RDS发生率显著低于对照组,不同孕周发生率亦不同,而且观察组患儿病情较对照组轻。 结论37~38周择期剖宫产产前使用激素值得推广。
