本文着重围绕超声检查技术在预测早产方面的发展基础与现状进行阐述,同时建议形成规范化的超声检测标准,以提高妊娠期早产风险预测评估的准确性,适时实施人工干预,从而降低早产儿的出生率及新生儿的死亡率、病死率。早产是指妊娠满足28周、但不足37周分娩者,占分娩总数的5%~15%~([1])。早产的原因分为自发性早产(早产和胎膜早破后早产)和治疗性早产。5%的早产发生在孕20~28周,12%发生在孕28~31周,
This article focuses on the ultrasound examination technology in the prediction of the basis for the development of preterm delivery and the status quo at the same time suggest the formation of standardized ultrasonic testing standards to improve the accuracy of risk assessment in preterm pregnancy assessment of pregnancy and timely implementation of manual intervention to reduce the birth rate of premature children And neonatal mortality, mortality. Premature delivery refers to 28 weeks of pregnancy, but less than 37 weeks of delivery, accounting for 5% to 15% of the total number of deliveries ([1]). The causes of preterm birth are divided into spontaneous preterm birth (premature rupture of membranes and premature rupture of membranes) and therapeutic preterm labor. 5% of preterm birth occurs in 20 to 28 weeks of pregnancy and 12% in 28 to 31 weeks of pregnancy,
