Significance of amniotic fluid index assessment in pregnancy induced hypertension

ABSTRACT

The significance of determination of amniotic fluid index [AFI] has been evaluated for antepartum fetal surveillance in 100 cases of pregnancy induced hypertension [PIH]. All the women were subjected to history taking, clinical examination, ultrasound assessment of AFI and fetal biometry. The frequency of oligohydramnios [AFI <5cm] in cases of PIH range from 8-10%, while the frequency of borderline oligohydramnios was 20%. Oligohydramnios was associated with abnormal FHR 70%, meconium stained AF grade II or III 70%, cesarean section CS for fetal distress 70%, 1-min. Apgar score <7 60%, and 5-min. Apgar score <7 20%. Also, AFI [<5 cm] was important in the prediction of fetal growth retardation in 60% of cases, while its negative predictive value was 83%. On the other hand, PIH with normal AFI had favorable findings regarding fetal outcome:
