围产医学中的高危妊娠一直是广大医务工作者工作的重点。近年来,我们对妊娠晚期及临产后高危妊娠者采用数胎动、B超检查、无负荷试验(NST)、羊膜镜检、测定尿E/C值作为综合指标,以期早期确诊胎儿宫内缺氧,适时终止妊娠,从而降低了新生儿窒息率及死亡率。 High-risk pregnancy in perinatal medicine has always been the focus of the work of medical workers. In recent years, we use fetal movement, B-ultrasound, no-load test (NST), amniotic microscopy and urinary E / C values ​​as a comprehensive index for late pregnancy and postpartum high-risk pregnancies in order to early detection of intrauterine hypoxia , Timely termination of pregnancy, thereby reducing neonatal asphyxia and mortality.
