Abstract:
Objective:To analyze diagnostic value of color Doppler ultrasound (B ultrasound) screening obstetric fetal abnormal condition. Methods:Using retrospective analysis, 1148 cases of pregnant women carried out prenatal B ultrasound examination were selected in our hospital from January, 2013 to June, 2013. B ultrasound examination data are complete, in order to postpartum, after induced labor or autopsy results as the standard, B ultrasound screening for fetal anomaly judgment before producing the accuracy, sensitivity and specificity. Results:Twelve cases of pregnant women were carried out abnormal fetal ultrasound examination, the detection rate was 1.05%(12/1148);after the induction of labor after multiparous, or autopsy results found that fetal abnormality were 13 cases, accounting for 1.13%;the sensitivity of ultrasound for fetal anomaly examination was 92.3%(12/13), the specificity was 100%(1135/1135), the accuracy was 99.9%(1147/1148), It had significant difference (x2=20.22, P<0.05). Conclusion:Prenatal ultrasonic examination system with safe, noninvasive, simple, good repeatability and high reliability,has an important value in the diagnosis of fetal abnormalities, and which has important clinical value to reduce the birth defect.
