Observation of the effect of standardized ultrasound examination in the screening of fetal malformation during early pregnancy

Abstract

Objective To investigate the application effect of standardized ultrasound examination in the screening of fetal malformation during early pregnancy. Methods Nine hundred and eighty-six cases of pregnant women with fetal malformation were selected from October 2014 to October 2015. All study subjects underwent standardized ultrasound examination; The prepotency consultation cases of fetal abnormalities were check out. In accordance with the wishes of pregnant women, they decided whether to continue pregnancy or labor induction, if they chose to continue pregnancy, made them understand the pregnancy outcome and neonatal condition clearly. According to the results of induced labor or follow-up results, the accuracy of ultrasound diagnosis in early pregnancy were counted. Results There were 27 cases of fetal malformation in 986 cases of pregnant women, 25 cases were examined by ultrasonography, the detection rate was 2.54% (25/986). Compared to 2.74% with follow-up results or abortion (27/986), there was no significant difference (P>0.05). The accuracy rate of ultrasound was 92.59% (25/27), of which cleft lip and palate accounted for 0.81% (8/986), exencephalia accounted for 0.20% (2/986), cardiac structural abnormalitie accounted for 0.10% (1/986), lower limb dysplasia accounted for 0.31% (3/986), cystic hygroma accounted for 0.41% (4/986), scoliosis accounted for 0.20% (2/986), no brain accounted for 0.51%(5/986). Conclusions The standardized ultrasound examination of pregnant women in early pregnancy can effectively detect fetal malformations, and the diagnostic accuracy is high. It can provide guidance for the formulation of intervention program and reduce the birth rate of deformed children.
