What does meconium in the amniotic fluid indicate?

Babies who are stressed by low oxygen levels or infections also may pass meconium before birth. When meconium gets in the amniotic fluid, there’s a chance a baby will breathe (aspirate) it into the lungs before, during, or after birth. But most babies with meconium in the amniotic fluid will not get MAS.

Is meconium in amniotic fluid normal?

Passage of meconium in the newborn infants is a developmentally programmed incident; normally occurring within the first 24 to 48 h after birth. However, the fetus may pass meconium in the amniotic fluid during pregnancy due to different reasons.

Can you see meconium on an ultrasound?

It has been suggested that meconium-stained amniotic fluid can be detected in the antepartum period by means of ultrasound, based on the following findings: (1) a diffuse echogenic pattern throughout the amniotic cavity, (2) a clear contrast between the amniotic fluid and the umbilical cord, and (3) layering in the …

What is particulate meconium?

Meconium aspiration syndrome (MAS) occurs when a neonate inhales thick, particulate meconium. This is usually secondary to fetal hypoxia which causes increased peristalsis, relaxation of anal sphincters and reflex gasping.

What is amniotic fluid aspiration?

Aspiration of meconium-stained amniotic fluid may occur if the fetus is in distress, leading to a gasping breathing pattern. This aspiration induces hypoxia via four major pulmonary effects: airway obstruction, surfactant dysfunction, chemical pneumonitis , and pulmonary hypertension.
