近年来,围产期(Perinatal stadium or period)在国际上被广泛重视,其目的是使母亲健康,分娩能正常进行,并且希望得到健康孩子。因此,围产期一词具有预防和治疗两方面意义。为了得到分娩中胎儿的情报,国外应用胎儿心音仪、胎儿心电图及超声多普勒(Doppler)诊断仪等,对分娩过程中的胎儿时刻进行监视;有人采取羊水和胎儿末梢血进行精密迅速的生化检查,以了解胎儿有无宫内窒息,以便早期发现问题,进行预防与治疗,因而大大降低了围产期死亡率(Perinatat mortality)。我国电子医疗仪器的研究取得了可喜的成就,许多厂已先后制造出各种类型的超声波诊断仪。我院使用河 In recent years, the perinatal stadium or period has gained international prominence. Its purpose is to make the mother’s health and childbirth normal and to expect healthy children. Therefore, the term perinatal period has both preventive and therapeutic implications. In order to get the fetus in the delivery of information, foreign application of fetal voice, fetal electrocardiogram and ultrasound Doppler (Doppler) diagnostic apparatus, during the delivery of fetal time monitoring; some people take amniotic fluid and fetal peripheral blood for rapid and rapid biochemical Check to find out whether the fetus has been asphyxiated intrauterine, in order to early detection of problems, prevention and treatment, thus greatly reducing the perinatal mortality rate (Perinatat mortality). China’s electronic medical equipment research has made gratifying achievements, many factories have created various types of ultrasonic diagnostic apparatus. I use the hospital river
