出现晚期减速监护图形往往是因为子宫—胎盘功能不良 ,发生缺氧 ,致胎儿心肌受抑制而引起 ,再加上宫缩和缺血触发胎心率晚期减速。所以晚期减速的出现 ,是胎儿预后不良的信号 ,易导致新生儿窒息、死亡 ,在临床开始后行胎心监护可作为及时了解胎儿能否承受产程进展的指标。现将 Late deceleration monitoring graphics is often due to uterine - placental dysfunction, hypoxia, caused by inhibition of fetal heart muscle, coupled with contractions and ischemia trigger fetal heart rate deceleration late. Therefore, the emergence of late deceleration, fetal adverse prognosis of the signal, easily lead to neonatal asphyxia and death, after the start of clinical fetal heart monitoring can be used as a timely understanding of the fetus can withstand the progress of labor index. Now
