Abstract
Background: Amniotic fluid is the protective liquid contained by
the amniotic sac of a gravid uterus. It is necessary for human fetal growth and
development. The amniotic fluid volume (AFV) depends on the gestational age.
AFV should be assessed at every prenatal ultrasound, as abnormalities in
amniotic fluid volume are associated with a wide range of pregnancy
complications.
Methods:
A retrospective study was done on the admitted patients of Maternal Fetal
Medicine Unit, Department of Obs and Gynae, Dhaka Medical College Hospital,
Bangladesh, during the year 2020. With due permission from department of Obs and Gynae and ethical clearance from appropriate committee, records of admitted
patients with abnormal amniotic fluid volume were reviewed and analyzed for evaluation
of their underlying etiologies and subsequent outcome of these pregnancies.
Results:
Among total 656 admitted patients 130 (19.8%) had oligohydramnios and 27 (4.1%)
had polyhydramnios. 76.9% of oligohydramnios was due to prelabour rupture of
membrane. Other associated conditions of oligohydramnios were hypertensive
disorders of pregnancy and growth restricted fetus (11.5%) , Diabetic disorders
(10.0%), Anomalous fetus (8.5%) and undetermined causes (2.3%). Polyhydramnios
was mainly associated with fetal anomaly (59.3%) but a little percentage was
associated with gestational diabetes (14.8%), multiple pregnancies (11.1%),
chorioangioma (3.7%) and undetermined (11.1%) causes.
Discussion: Though idiopathic causes were found in a considerable
percentage for amniotic fluid disorders in previous literatures and texts, we
found that some abnormalities of pregnancy are almost always present with this.
Conclusion: It is important to keep an eye on amniotic fluid
index for better pregnancy outcome.
