Varying degrees of oligohydramnios on the impact of late pregnancy outcome

Objective: To explore the varying degrees of oligohydramnios on the impact of late pregnancy outcome Methods: From September 2007 to August 2009 in in-patient obstetric delivery in our hospital,480 cases of maternal oligohydramnios observation group were selected,and according to amniotic fluid index(AFI),were divided into two groups: Group A of amniotic fluid index≤5 cm,Group B of amniotic fluid index 5 cm and≤ 8 cm,and the 480 examples in the same period with normal parturient were the control group,and the clinical observations were made of the pregnancy results,and compared with observation group and control group and the pregnancy results of the two groups of A and B.Results: There was statistically significant difference in the delivery gestational weeks,mode of delivery,fetal growth restriction,meconium-stained amniotic fluid,neonatal asphyxia between the observation group and the control group.There was statistically significant difference in the mode of delivery,meconium-stained amniotic fluid,neonatal asphyxia in groups of A and B divided according to amniotic fluid index(P0.01),and there was no statistically significant difference in the two groups in delivery gestational weeks and fetal growth restriction(P0.05).Conclusion: The amniotic fluid index(AFI) should be considered as routine antenatal monitoring indicators,and when the amniotic fluid index≤5 cm pregnancy result is bad,the prompt cesarean termination pregnancy should be adopted.When the amniotic fluid index5 cm and≤ 8 cm,vaginal trial delivery can be adopted in the intensive care intrauterine circumstances.
