过期妊娠357例临床分析

The clinical analysis of prolonged pregnancy on 357 cases

①目的通过对357例过期妊娠的临床分析,了解过期妊娠对母儿的不良影响,评价胎儿生物物理评分在其监测中的意义。②方法采用回顾性分析方法,与同期足月妊娠714例作对照并进行统计分析。③结果过期妊娠的剖宫产率是足月妊娠的1.6倍,产后出血是对照组的3.3倍,新生儿窒息,新生儿胎粪吸入综合征的发生率增加。④结论过期妊娠使剖宫产率上升,产后出血的发生率增加,是胎儿窘迫、新生儿窒息、新生儿胎粪吸入综合征发生的原因之一。用胎儿生物物理评分监测过期妊娠是可行的。

Objective Base on the clinical analysis about 357 cases of prolonged pregnancy, this paper make clear harmful effects of the prolonged pregnancy to mothers and babies, and appraise the important meanings of Biophysical Profile Score（PBS） in control. Method Retrospective materials research, compared with the 714 cases of uterogestation at the same period. Results The C - sect rate of post - term pregnancy is 1.6 times of uterogestation, postpartum hemorrhage is 3.3 times of controls,neonatal asphyxia and newborn meconium inhalation rate will increase. Conclusions Prolongedpregnancy increase the C -sect rate and the postpartum hemorrhage rate. It is one of the causes of fetal distress ,neonatal asphyxia and newborn meconium inhalation.
