How much fluid should be present can become a concern for some women during pregnancy. As the baby grows, it produces more amniotic fluid. The amount increases until the baby is about 32 weeks ...

In approximately 5% of infants with meconium-stained amniotic fluid, meconium aspiration syndrome develops; in 9.6% of patients with meconium aspiration syndrome, a pneumothorax develops. 1,2 On ...
