从五十年代起,B型超声波诊断仪开始应用于产科临床,推动了围产期保健的迅速发展,也为产前诊断提供了一种简便、可靠的方法。但是,关于B超检查对胚胎究竟有没有影响的问题。众说纷纭,始终没有解决。多数材料来源于体外研究,不能很好地反映体内发生的真实情况。因此,本文选择欲做人工流产的孕早期妇女为研究对象,探讨超声波对早孕胚胎细胞的遗传学效应,为客观评价B超在产前诊断应用的安全性提供一些资料。
Since the 1950s, the B-type ultrasonic diagnostic apparatus has been used in obstetrics clinics, promoting the rapid development of perinatal care, and also providing a convenient and reliable method for prenatal diagnosis. However, on the B-ultrasound on the embryos have no effect on the issue. Different opinions have not been resolved. Most materials come from in vitro studies that do not adequately reflect the true conditions in the body. Therefore, this article chooses the pregnant women who want to do abortion as the research object, probes into the genetic effect of ultrasound on embryonic cells of early pregnancy, and provides some information for the objective evaluation of the safety of B-ultrasound in prenatal diagnosis.
