目的研究超声诊断在出生缺陷产前诊断中的应用价值。方法 1081例孕妇,对其胎儿畸形率和超声诊断准确率进行统计分析。结果所有孕妇中,国家卫生部规定的六大畸形种类由超声诊断的准确率为100.00%,但其他种类的畸形均有漏诊现象发生,其中以小型畸形为主,整体而言,胎儿畸形率为1.83%,总漏诊率为13.67%;在检测时机方面,孕期17~28周进行检测的准确率较高,<17周或>28周的准确率较低。结论对胎儿的超声诊断应该选择在孕中期进行,这样才能及时发现畸形现象,采取有效应对措施,降低出生缺陷发生率。
Objective To study the value of ultrasonic diagnosis in prenatal diagnosis of birth defects. Methods A total of 1081 pregnant women were enrolled in this study. The fetal malformation rate and the diagnostic accuracy of ultrasound were statistically analyzed. Results All pregnant women, the national Ministry of Health prescribed by the six major deformities by ultrasound diagnostic accuracy rate was 100.00%, but other types of deformity have missed diagnosis, of which the main small deformity, overall, the fetal malformation rate 1.83%, the total misdiagnosis rate was 13.67%; in the detection timing, pregnancy 17 to 28 weeks to detect the accuracy rate is higher, <17 weeks or> 28 weeks lower accuracy. Conclusion Ultrasound diagnosis of the fetus should be carried out in the second trimester so as to detect abnormalities in time and take effective measures to reduce the incidence of birth defects.
