孕中期B超筛查在控制出生缺陷发生率中的作用研究

Research on the clinical effect of B ultrasound in the incidence rate of the neonate′s birth defect at the second trimester

目的探讨孕中期B超筛查在控制出生缺陷发生率中的作用。方法选择2015年1月~2016年12月来我院行产前检查的1897例孕中期女性作为研究对象,所有孕妇均以四维超声技术对胎儿生长发育情况进行体检,判断胎儿是否先天性畸形,决定是否行产科干预措施(引产)。将B超检查结果与妊娠结果、引产结果进行比较,分析B超在筛查孕中期缺陷儿的准确率情况。结果 B超检查共发现26例胎儿有出生缺陷,发生率为1.37%,类型包括重度脑室扩张8例,唇腭裂3例,心脏强光点3例,肾盂扩张2例,关节屈曲1例,胃肠道畸形2例,多指3例,脊柱侧弯3例,足内翻指1例,本次胎儿畸形B超诊断准确率为92.9%。结论超声是临床胎儿生长检查、筛选缺陷儿的重要手段,能有效反映胎儿是否出现畸形,对临床减少缺陷儿出生有重要意义。

Objective To observe the clinical effect of the prenatal examination of B ultrasound in the incidence rate of the neonate′ s birth defect at the second trimester.Methods 1897 second trimester of pregnant women checked from January 2015 to January 2016 in our hospital were selected as research subjects.The four-dimensional ultrasound technique was used to observe the neonates′ growth conditions in determining whether there were congenital malformation and whether it was necessary to take the intervention measures（labor induction）.According to the B ultrasound examination results,pregnancy outcomes and labor induction conditions,the detection accuracy of B ultrasound was analyzed.Results According to the B ultrasound examination results,there were 26 neonates of birth defects（1.37%） including 8 cases of severe ventricular dilation,3 cases of cleft palate,3 cases of brightly spotted heart,2 cases of pyelectasis,1 case of flexion of the joints,2 cases of gastrointestinal malformation,3 cases of polydactyly,3 cases of scoliosis and 1 case of ？strephenopodia.The detection accuracy of B ultrasound was 92.9%.Conclusion The B ultrasound is an important method of examining the neonate′ s growth and screening the birth defects,can display whether the neonates have the malformations.
