重度妊高征终止妊娠时机及方式的研究

目的　研究重度妊高征患者不同孕周、不同方式终止妊娠对母婴的影响。方法　回顾性分析5 1例重度妊高征患者及其围生儿,比较不同孕周、两种分娩方式与母婴预后的关系。结果　重度妊高征患者在32～37孕周终止妊娠者,其胎盘早剥、胎儿宫内窘迫的发生率明显低于≥37孕周终止妊娠组(P <0 . 0 5 ) ,而两组新生儿窒息、新生儿肺透明膜病的发生率无显著性差异(P >0 . 0 5 )。而剖宫产分娩组并发产后出血、产时产后子痫明显低于阴道分娩组(P <0 . 0 5 )。结论　重度妊高征患者如病情需要,可将妊娠终止提前至32～37孕周之间,剖宫产指征应适当放宽。

STUDY OF THE TIME AND METHOD OF PREGNANCY TERMINATION IN SEVERE PREGNANCY INDUCED HYPERTENSION

Objective To study the influences of gestational age and natal mode of pregnancy termination on mothers and infants in severe pregnancy induced hypertension (PIH). Methods 51 pregnant women suffered from severe PIH were enrolled for retrospective analysis. The relationships between different gestational ages, two natal modes and the prognosis of mothers and infants were compared. Results When the pregnancy were terminated at 32～37 weeks of gestation, the rates of placental abruption and fetal distress were significantly lower than those when the pregnancy were terminated at ≥37 weeks (P<0.05). And there were no significant difference in rates of neonatal asphyxia and neonatal pulmonary hyaline membrane between the two groups (P>0.05). The patients with cesarean section had lowered rates of postpartum hemorrhage and eclampsia compared with those in patients with vaginal delivery (P<0.05). Conclusion In severe PIH, pregnancy should be terminated ahead of the time at 32～37 weeks according to the patient’s condition. The indication of cesarean section should be adequately relaxed.
