目的:探讨医源性早产的指征,促胎肺成熟药物的作用,分娩时机的选择及终止妊娠的方法。方法:对本院126例医源性早产患者进行回顾性分析。结果:医源性早产最常见因素为妊高征(35.71%),其次为妊娠合并内科疾病,以及前置胎盘等。随着孕周增加,尤其是33周以后,在有计划地应用促胎肺成熟药物下,早产儿窒息率、发病率和死亡率均明显下降。结论:对不可避免的医源性早产,产前定期检查和适当干预,选择恰当孕周终止妊娠可取得良好的妊娠结局。 Objective: To explore the indications of iatrogenic preterm birth, the role of promoting fetal lung mature drugs, the timing of childbirth and the method of termination of pregnancy. Methods: 126 cases of iatrogenic preterm birth in our hospital were retrospectively analyzed. Results: The most common cause of iatrogenic preterm birth was pregnancy-induced hypertension (35.71%), followed by pregnancy-associated medical diseases and placenta previa. As gestational weeks increased, especially after 33 weeks, there was a significant reduction in asphyxia, morbidity and mortality in preterm infants under the planned application of mature fetal lung growth regulators. CONCLUSIONS: Good pregnancy outcomes can be achieved for the inevitable iatrogenic preterm, prenatal periodic exams and appropriate interventions, and the choice of the appropriate gestational age for termination of pregnancy.
