Comparison of Outcome of Borderline and Normal Amniotic Fluid Index in Term Pregnancy
Ansari SN, Baral J, Gurung G, Jha A
Abstract: Background
Determination of Amniotic Fluid Index (AFI) is an important component of antepartum
assessment of all normal pregnancies.
Objective
To compare the obstetric interventions and neonatal outcomes in term pregnancies
with borderline Amniotic Fluid Index versus normal Amniotic Fluid Index.
Method
This hospital based prospective study was conducted at Tribhuwan University
Teaching Hospital over 1 year between 2017 and 2018 in 128 women having
uncomplicated term pregnancy admitted in labor ward. Of the 128 women, 64
women had borderline Amniotic Fluid Index (5.1-8 cm) and 64 normal AFI (8.1 - 24
cm). Parameters studied were induction of labor, cesarean section, instrumental
delivery, intrapartum abnormal fetal heart rate, meconium staining of liquor, APGAR
score at 5 and 7 minutes, birth weight, neonatal intensive care unit (NICU) admission
and neonatal death. Data was analyzed using software OpenEpi.
Result
Statistically significant difference in result was obtained in the two groups in terms
of rate of induction of labor (73.4% vs 35.9%, p = 0.0001, OR = 4.9), rate of cesarean
section (42.1% vs 28 .1%, p = 0.04, OR = 1.8), tachypnea (50% vs 11.1%, p = 0.01)
and low birth weight (9.1% vs 4.5%, p = 0.04). No statistical significance was found
in meconium staining of liquor (33% vs 38.3%, p = 0.3) and APGAR score of <7 at
5 minutes (3.1% vs 1.5%, p = 0.06). There were no neonatal intensive care unit
admissions and neonatal mortality in any of the babies.
Conclusion
Detection of amniotic fluid volume at term is important for timely maternal
interventions to improve the overall fetal outcome.
