引起新生儿期心肺症状的疾病包括先天性心脏病(CHD)、心律不齐、胎儿及新生儿循环转化异常,母亲有糖尿病或低血糖等时引起的无形态学异常的心血管疾病、呼吸窘迫综合征、败血症等。近年来,由于胎儿超声心动的进展,至今未明的胎儿循环异常及胎儿、新生儿期的一系列疾病逐渐得到了认识。胎儿期心脏病利用超声断层检查可了解胎儿的发育、胎盘位置、羊水以及胎儿的畸形,亦可发现胎儿心脏病。一般高龄孕产妇患有各种心脏病、代谢病、胶原病、风疹、羊水过多、RH 不合以及用过酒精、镇静药、阿斯匹林等药物者有 CHD、染色体异常、畸形综合征等家族史者以及胎儿有心律不齐、胎动减少等情况下,在妊娠20周前后和28周前后应进行超声波检查,
Diseases that cause cardiorespiratory symptoms during the neonatal period include congenital heart disease (CHD), arrhythmia, abnormal fetal and neonatal circulatory abnormalities, cardiovascular morbidity in mothers with or without morphological abnormalities such as diabetes or hypoglycemia, respiratory distress Syndrome, sepsis and so on. In recent years, due to the progress of fetal echocardiography, so far unknown fetal circulation abnormalities and fetuses, a series of diseases in the newborn period has been gradually recognized. Fetal heart disease using ultrasound tomography can understand the development of the fetus, placental position, amniotic fluid and fetal malformations can also be found in fetal heart disease. General elderly pregnant women suffering from heart disease, metabolic disease, collagen disease, rubella, polyhydramnios, RH substandard and used alcohol, sedatives, aspirin and other drugs were CHD, chromosomal abnormalities, malformation syndrome Family history and fetal arrhythmia, fetal movement and other circumstances reduced, before and after 20 weeks of pregnancy and 28 weeks before and after ultrasound should be carried out,
