INCIDENCE OF LOW BIRTH WEIGHT IN PREGNANT WOMEN WITH ISOLATED OLIGOHYDRAMNIOS

ABSTRACT
Introduction: Oligohydramnios affect 3% to 5% of pregnancies and is associated with increased pregnancy complications,
congenital anomalies and perinatal mortality. Therefore, adequate amniotic fluid volume is critical for the
normal fetal growth and development. Large scale national data showing the incidence of oligohydramnios in Pakistan
is lacking. Therefore, we conducted the study to determine the frequency of low birth weight in pregnant women with
isolated oligohydramnios.
Material and Methods: This descriptive cross-sectional study was carried out in the department of obstetrics and
gynecology Hayatabad Medical Complex, Peshawar from April 2015 to Oct 2015. This study included a total of 124
patients using non probability consecutive sampling technique for sample collection. Women with singleton pregnancies
at term 37 to 40 wks with non anomalous fetuses and with intact membranes and cephalic presentation and with
isolated oligohydramnios were included in study.
Results: Our study shows that among 124 women, 67 (54%) women were primi gravida while 57(46%) women were
multi gravida. Mean age was 26 years (SD ± 4.37) and mean parity was 3 (SD ± 2.02). Mean gestational age of patients
was 38 weeks with SD ± 1.22. Low Birth weight among 124 patients was analyzed as 19(15%) neonates had
birth weight ≤ 2.5 Kg, 105(85%) neonates had birth weight > 2.5 Kg, Mean birth weight was 3.5 Kg with SD ± 4.62.
Conclusion: Our study concludes that the incidence of low birth weight was found to be 15% in pregnant women with
isolated oligohydramnios.
