The fluid that collects within the amniotic cavity surrounding the embryo is called AMNIOTIC FLUID or LIQUOR AMNII. Amniotic fluid that surrounds fetus in amniotic sac provides several benefits to the fetus [1]. It provides a protected milieu for the growing fetus, cushioning the fetus against mechanical and biological injury, supplying nutrients and facilitating growth and movement. Quantification of amniotic fluid is an important component of the biophysical profile in ultrasound evaluation of fetal wellbeing, especially in the third trimester [2]. Amniotic fluid volume varies with gestational age. Amniotic fluid volume increases up to 34 weeks of gestation which is then followed by a slow decline [3]. Abnormalities of volume may be associated with increased risks for adverse pregnancy outcome.
