  • Meconium Aspiration Syndrome

    a condition caused by inhalation of meconium into the lung of fetus or newborn, usually due to vigorous respiratory movements during difficult parturition or respiratory system abnormalities. meconium aspirate may block small airways leading to difficulties in pulmonary gas exchange and aspiration pneumonia.

  • Neonatal Aspiration Syndrome

    aspiration of meconium, blood, amniotic fluid or gastric contents around the time of delivery resulting in clinical symptoms from airway obstruction, parenchymal injury, and ventilation-perfusion mismatch. this may lead to persistent pulmonary hypertension in the newborn.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
