Meconium aspiration syndrome (MAS), also known as neonatal aspiration of meconium, is a medical condition affecting newborn infants. It describes the spectrum of disorders and pathophysiology of newborns born in meconium-stained amniotic fluid (MSAF) and have meconium within their lungs.
The syndrome develops in about 20% of human pregnancies continuing past the expected delivery date. [3] Features of post-maturity syndrome include oligohydramnios (a deficiency of amniotic fluid); [4] meconium aspiration (breathing meconium in the amniotic fluid); and macrosomia (being overly large).
It has also been used to reduce the risk of meconium aspiration syndrome, though evidence of benefit is mixed. [2] [3] [4] The UK National Institute of Health and Clinical Excellence (NICE) Guidelines recommend against the use of amnioinfusion in women with meconium stained amniotic fluid (MSAF). [5]
It is associated with complications such as cord compression, abnormal heart rate, fetal acidosis, and meconium amniotic fluid. [10] Meconium aspiration syndrome – Respiratory compromise secondary to meconium present in infant's lungs. [11] Macrosomia – Excessive birth weight, estimated fetal weight of ≥ 4.5 kg.
Pleural effusions can also develop, which are also seen with meconium aspiration but not with respiratory distress syndrome. [2] The lungs may also appear hyperinflated. [5] It is a diagnosis of exclusion as it is a benign condition that can have symptoms and signs similar to more serious syndromes, such as respiratory distress or meconium ...

Perinatal asphyxia (also known as neonatal asphyxia or birth asphyxia) is the medical condition resulting from deprivation of oxygen to a newborn infant that lasts long enough during the birth process to cause physical harm, usually to the brain.
According to the AAP 2020 Guidelines, neonatal testing refers to laboratory testing of the infant's urine, meconium, and umbilical cord tissue. [29] Although these tests are recommended per guidelines, there are several considerations to understand when performing these tests.
