Abstract:Background: The amniotic fluid is the fluid that collects within the amniotic cavity surrounding the embryo. It is an ultrafilrate of maternal plasma. The main source of amniotic fluid is fetal urination. Another important source is fetal lungs which produces fluid that exits respiratory tract and enters amniotic compartment. The volume of amniotic fluid increases rapidly with the growth of products of consumption of about 50 ml at 12 weeks of pregnancy; 400ml at 20 weeks and at 36 weeks it’s about 1000 ml. During the last few weeks of pregnancy its volume decrease about 600-800ml. At 43 weeks it is about 100-600 ml. This present study is to assess the amniotic fluid index of <= 5cm in term pregnancies.
