规范化产前超声检查对胎儿缺陷检测率的影响

Effect of standardized prenatal ultrasonography on the detection rate of fetal defects

目的研究规范化产前超声检查对胎儿缺陷检测率的影响。方法选择我院2013年4月～2015年8月期间2488例妊娠12周至足月分娩的孕妇。其中2013年4月～2014年2月期间未实施规范化产前超声，2014年3月～2015年8月期间实施规范化产前超声，观察规范化产前超声实施前后对胎儿缺陷检测率的影响。结果实施规范化产前超声后不同孕周检出率均高于实施前（P〈0．05）。实施后不同畸形类别漏诊率均低于实施前（P〈0．05）；肢体畸形漏诊率明显低于其他类别（P〈0．05）。结论规范化产前超声可有效提高胎儿缺陷的检测率，是检查胎儿发育异常和预防出生缺陷的重要手段。

Objective To study the clinical effect of normalized prenatal uhrasonography in the detection rate of fetal defects. Methods 2488 pregnant women with 12w of gestation to full-term delivery checked from April 2013 to August 2015 in our hospital were selected. From April 2013 to February 2014, the prenatal uhrasonography was not normalized; from March 2013 to August 2015, the prenatal uhrasonography was normalized. The clinical effect of normalized prenatal uhrasonography in the detection rate of fetal defects was observed. Results After intervention, the detection rate of fetal defects for the pregnant women with different gestation weeks was higher than before （P 〈 0.05）; after intervention, the rate of missed diagnosis on the types of fetal malformation was lower than before （P 〈 0.05）; the rate of missed diagnosis on the limb deformity was lower than the other malformation types （P 〈 0.05）. Conclusion The normalized prenatal ultrasonography can improve the detection rate of fetal defects. It is considered as the important method of detecting the fatal malformation and reducing the birth rate of abnormal children.
