延期妊娠318例临床分析

Suitable treatment of the delayed pregnancy

目的探讨延期妊娠对围生儿的影响及其临床处理对策。方法收集安徽医科大学第一附属医院2002年1月至2004年4月间收治的318例延期妊娠的临床资料,并随机抽取同期我院收治的318例足月妊娠资料,两组相对比。结果延期妊娠组羊水过少、羊水污染、胎儿宫内窘迫、新生儿窒息、剖宫产等发生率较足月妊娠明显增高(P<0.01),两组间巨大儿、低体重儿发生率无显著差异(P>0.05)。结论延期妊娠时胎盘功能减退、胎儿宫内环境差、胎儿对缺氧耐受性降低、高危程度增加,故应积极采取措施,适时计划分娩,产前产时需严密监护,以确保母婴安全。

Objective To explore the effect of delayed pregnancy on perineonate and its suitable treatment. Methods We collected the clinical data of 318 patients with delayed pregnancy in our hospital from January 2002 to April 2004. and 318 patients with normal pregnancy were selected randomly as control group. Results For the delayed pregnancy group,74 cases were at placental maturity Ⅲ degree,69 cases of oligohydramnios,71 cases at amniotic fluid turbidity Ⅱ-Ⅲ degree,79 cases of fetal distress,41 cases of neonatal asphyxia,51 cases delivered from the vaginae, 139 cases of cesarean section. The occurance rates of placental maturity Ⅲ dgree, oligohydramnios, amniotic fluid turbidity Ⅲ-Ⅲ degree, fetal dis- tress, neonatal asphyxia, and cesarean section were significantly higher than those in normal pregnancy group （P 〈 0.01 ）. As to large-for-dates infants and low birth weight infants, there were no significant difference （P〉0.05）. Condusion More dangerous situations would occur to the fetus resulting from decreasing function of placenta in delayed pregnancy. The incidence of delayed pregnancy will be decreased and mother with fetus will be safer by close monitor during antepartum and intranartum period.
