摘要
目的:探析彩色多普勒超声(B超)筛查产科胎儿异常状况的诊断价值。方法:回顾分析1148例行产前检查的孕妇临床资料,以产后、引产后或尸检结果为标准,判断产前行B超筛查胎儿异常的准确性、灵敏度和特异度。结果:B超检查出12例胎儿异常,检出率为1.05%(12/1148);经产后、引产后或尸检结果发现,胎儿异常共13例(占1.13%);B超对胎儿异常检查的灵敏度为92.3%(12/13),特异度为100.0%(1135/1135),准确率为99.9%(1147/1148),差异有统计学意义(x2=20.22,P<0.05)。结论:产前系统B超检查具备安全、无创、简便、重复性好和准确度高的特点,对胎儿异常具有重要诊断价值,且对减少出生缺陷具有重要临床价值。
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, P0.05）. 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.
