妇幼保健机构开展胎儿系统产前超声筛查的临床意义

目的：探讨开展胎儿系统超声产前筛查的重要性。方法应用西门子S-2000彩色多普勒超声诊断仪及VOLUOSENE 8、E6彩色多普勒超声诊断仪对孕20~26周1825例孕妇进行系统超声产前筛查。结果胎儿发育异常38例，畸形发生率占2%（38/1825）。产前超声诊断、经引产或出生后证实的胎儿畸形病例共在我院住院引产29例，外院追踪符合病例9例，漏诊1例（晚孕时发现手指缺陷），诊断符合率为98%（38/39）。结论超声产前系统筛查有效降低了畸形儿的出生率，对临床有重要指导意义。

Clinical significance of prenatal fetal systematic ultrasound screening in maternal and children health institutions

Objective To explore the importance of prenatal fetal systematic ultrasound screening. Methods Siemens S-2000 color Doppoler ultrasonic diagnosis system and VOLUOSENE8, E6 color Doppoler ultrasonic diagnosis system were applied for prenatal systematic ultrasound screening on 1825 pregnant women with pregnancy froun 20 to 26 weeks. Results 38 cases of abnormal fetal development were observed, with malformation rate of 2%（38/1825）. As for fetal malformation cases confirmed by prenatal ultrasonic diagnosis, induced labor or postnatal diagnosis, 29 cases were hospitalized and born in our hospital, 9 cases were traced in other hospitals, and 1 case had missed diagnosis（finger defect detected at late pregnancy）, with diagnostic accordance rate of 98%（38/39）. Conclusion Prenatal sys-tematic ultrasound screening can effectively reduce the rate of children with birth defects, which is of important guid-ance for clinical practice.
