彩色多普勒,,彩色多普勒超声；安全阈值,1对象与方法,2结果,讨论,【参考文献】
【摘要】 目的 探讨诊断性彩色多普勒超声的安全性，以期为建立诊断超声的安全阈值提供一定的依据。方法 随访的520例孕妇所生的526例婴儿(双胎6例)作为研究组；并以485例怀孕期间从未接受过超声检查的孕妇所生的婴幼儿作为对照组。对病例进行回顾性总结，分析超声对胎儿生长受限、畸形发生率、围产儿死亡率、儿童智力、身高和体重是否有影响。结果 研究组与对照组胎儿生长受限、畸形发生率和围产儿死亡率差异无显著性(P>0.05)。但研究组中接受过5次以上的75例孕妇中有3例发生胎儿生长受限，而儿童智力、身高和体重因素差异无显著性。结论 使用诊断超声强度对胎儿是安全的。【关键词】 彩色多普勒超声；安全阈值

【Abstract】 Objective To study the safety of diagnostic color Doppler ultrasound in obstetrics and provide some clinical evidences for establishing the safety threshold.Methods 520 examples pregnant women with 526 babies were enrolled as research group.And 485 examples never accept supersonic inspection during pregnant period were allocated to comparison group.Retrospective analysis was carried out to compare the difference between the two groups with regard to the incidence of fetal growth resfraining,malformation,peripartum mortality,childrens intellegence,height and weight.Results The difference between the two group was not signifcant (P>0.05).Among 75 cases who underwent over 5 times of ultrasonography,3 fetum incurred growth suppression with no intellegence defect.Conclusion Our performance of diagnostic ultrasound is safe to embryos. ......
