目的:探讨规范产前超声检查诊断胎儿畸形的价值。方法:应用彩色多普勒超声诊断仪,对2008年8月～2010年8月来该院行产前检查的孕妇42 080例按照胎儿超声筛查规范进行检查,并与引产及活产进行对照。筛查分4阶段:11～17周、18～24周、25～32周、33～足月,对胎儿进行Ⅲ级产前检查,显示的主要切面图像录入工作站。将实施规范产前检查后的检出率与实施前2年内进行对照。结果:规范产前超声检查后胎儿畸形的发生率为14.26‰,11～17周检出41例、18～24周检出135例、25～32周检出226例、33～足月检出194例。检出率从实施前的63.14%(221/350)提高到实施后的95.64%(570/596)。结论:规范的产前超声检查在诊断胎儿畸形中具有重要的价值,降低了出生缺陷率。
Objective: To investigate the value of prenatal ultrasound in the diagnosis of fetal malformations. Methods: A total of 42 080 pregnant women who came to the hospital from August 2008 to August 2010 were examined according to the fetus ultrasound screening standard and compared with the induction of labor and live birth . Screening in four stages: 11 to 17 weeks, 18 to 24 weeks, 25 to 32 weeks, 33 to term, the fetus for prenatal examination Ⅲ, the main section of the image input workstation. The implementation of standardized prenatal care after the detection rate compared with 2 years before the implementation of control. Results: The incidence of fetal malformation was 14.26 ‰ after standardized prenatal ultrasound examination, 41 cases were detected in 11-17 weeks, 135 cases were detected in 18-24 weeks, 226 cases were detected in 25-32 weeks, and 33 cases were detected in term 194 cases. The detection rate increased from 63.14% (221/350) before the implementation to 95.64% (570/596) after the implementation. Conclusion: The standardized prenatal ultrasonography has important value in the diagnosis of fetal malformation, and reduces the birth defect rate.
