105例第二产程电子胎心宫缩图(CTG)可归纳为基线变异增大,轻VD(可变减速)、重VD、晚期减速、心动过缓+宫缩时加速、轻VD+晚减成份(LDC)、重VD+LDC 及延长减速(PD)等8类.从新生儿出生情况看出,逐渐加重的VD、频发VD 及基线变异增大是胎儿宫内窘迫的警戒图型.7例新生儿窒息中5例CTG 为重VD+LDC 及PD,故可视为不祥图型.19例监护到胎头娩出者,5例出现了分娩终末期胎心减速(ESD),及时结束分娩,新生儿情况良好.重复PD 出现应于10分钟内娩出胎儿,重VD+LDC 20分钟内娩出胎儿,警戒图型30分钟内娩出胎儿.
105 cases of second-stage electronic fetal heart rate (CTG) can be summarized as baseline variation increased, light VD (variable deceleration), heavy VD, late deceleration, bradycardia + contractions acceleration, light VD + late ingredients (LDC), heavy VD + LDC and extended deceleration (PD), etc. According to the newborns’ birth, the gradual increase of VD, frequent VD and increase of baseline variation are the alert patterns of fetal distress.7 Cases of neonatal asphyxia in 5 cases of CTG for the heavy VD + LDC and PD, it can be considered ominous pattern .19 cases of custody to the fetal head delivered, 5 cases of end of childbirth fetal heart rate deceleration (ESD), the timely end of childbirth , Newborns in good condition.Repeated PD should be delivered within 10 minutes of the fetus, VD + LDC within 20 minutes of delivery of the fetus, vigilance pattern within 30 minutes of delivery of the fetus.
