自从超声诊断仪问世以来,人类优生学又向前推进了一大步。医生借助灰阶实时超声显像仪能把胎儿在宫内的形成、发育成长以至分娩过程生动而形象地描绘出来.通过对胎儿的多指标监测可以较准确地确定孕龄、胎儿发育情况和胎盘的成熟度.这对高危妊娠尤为重要.例如对胎儿发育迟缓、胎儿宫内缺氧等得以及时治疗;使真正过期妊娠的胎儿及时娩出;使大部分不能矫正的缺陷儿及时中止妊娠.超声监测为提高胎儿质量,降低围产儿病死率正在发挥其重要作用。
Since the advent of ultrasound diagnostic systems, human eugenics has taken another major step forward. With gray-scale real-time ultrasound imaging, the fetus can vividly and vividly describe the formation, development and growth of the fetus in the uterus and the childbirth process.The multi-index monitoring of the fetus can accurately determine the gestational age, fetal development and placenta Of maturity .This is particularly important for high-risk pregnancies .For example, fetal growth retardation, intrauterine hypoxia can be promptly treated; so that the real expired pregnancy fetus timely delivery; make most of the defects can not be corrected timely termination of pregnancy. To improve the quality of the fetus, reducing perinatal mortality is playing an important role.
