本文回顾性分析脐带隐性脱垂57例,其发生率为0.57%,高于同期显性脐带脱垂.本组新生儿窒息率为21.1%,其中重度窒息达10.5%,较同期总新生儿窒息率为高,剖宫产率为66.7%,为同期总剖宫产率的3倍.临床表现主要为胎心率突然减慢,占37例(64.9%),体位改变可使其好转.发生于破膜后者占78.9%,其中人工破膜为33.3%,自然破膜为45.6%.处理主要为改变体位,如床脚抬高、侧卧、胸膝卧位、上推胎头和及时终止妊娠.本病发生于枕先露者多于臀先露,先露在棘上0.5cm以上者较多,在自然破膜、人工破膜、推动胎头后胎心突然减慢者达61.4%,故对先露较高、前羊水囊较充盈者,在破膜或阴道手术操作时应警惕本病的发生.
This retrospective analysis of 57 cases of umbilical cord recessive prolapse, its incidence was 0.57%, higher than the same period of dominant umbilical cord prolapse in this group of neonatal asphyxia was 21.1%, of which severe asphyxia reached 10.5%, compared with the same period total neonates Asphyxia rate was high, the rate of cesarean section was 66.7%, which was 3 times of the total cesarean section rate in the same period.The clinical manifestations were mainly sudden abortion of fetal heart rate, accounting for 37 cases (64.9%). Occurs in the rupture of the latter accounted for 78.9%, of which artificial rupture of the membrane was 33.3%, natural rupture of the membrane was 45.6% .The main treatment is to change the position, such as bed foot elevation, lateral, chest knee supine, push the fetal head and Timely termination of pregnancy.The disease occurred in the first pillow exposed more than the buttocks first revealed more than 0.5cm above the spines are more in the natural rupture of membranes, artificial rupture of membranes to promote fetal heart rate fetal heart rate suddenly dropped 61.4%, so the first exposed higher, the former amniotic fluid filled than those in the rupture of membranes or vaginal surgery should be wary of the occurrence of this disease.
