To Analyse the Significance of Reduced Amniotic Fluid Index in Pregnancy and its Correlation with Perinatal Outcome
Objective: To assess the effects of reduced amniotic fluid index (AFI) at term gestation on perinatal outcome.
Methodology: This cross-sectional was conducted in Gynaecology and obstetrics Unit-III, at Liaquat University Hospital Hyderabad from 13 September 2015 to 12 March 2016. It is comprised of 72 patients having decreased amniotic fluid levels with gestational amenorrhea between 37-42 weeks, admitted in active labour through casualty and outpatient department of Liaquat University Hospital Hyderabad. All pregnant women with singleton pregnancy and decrease amniotic fluid levels with gestational amenorrhea of 37-42 weeks were included in this study. In addition to that, the neonates of these women were observed for one week after birth by enquiring their condition through phone calls. All the information was collected via predesigned proforma. Data was analyzed by using SPSS version 21.
Results: The mean age of the patients 30+3.1 years. Most of the patients were multipara 45.85%. Amniotic fluid index on ultrasound measured 3-4cm was women 51.38% cases, 1-2cm in 13.88% and 5-6cm in 34.72% of the women. APGAR score in 5min was observed < 6 in 51.38% cases and > 6 in 45.83%, whereas 2.77% were stillbirth with APGAR 0. Neonatal outcome at the end of 1st week of life, from 70 alive infants 30 who needed NICU care 10(14.28%) had birth asphyxia, 14(20%) had respiratory distress (these 24 neonates were lost from follow-up after one week) and 06(8.5%) died. Whereas other 40 neonates were remaining normal at the end of 1st week.
Conclusion: Oligohydramnios at term gestation increase the risk of cesarean delivery and increase NICU admission due to low APGAR score so the assessment of low amniotic fluid index at term gestation is a good predictor of adverse prenatal outcome.
