Dargaville PA. of all live births), meconium aspiration syndrome (1.3%) and respiratory distress syndrome (1.2%) were the three common causes of respiratory morbidity among inborn neonates admitted to various hospitals that formed part of the Consortium7. Aspirated meconium can interfere with normal breathing by several mechanisms including airway obstruction, chemical irritation, infection and surfactant inactivation and induces more or less severe signs of respiratory distress at birth. diagnosis. Mortality in meconium aspiration syndrome in hospitalized babies Mortality rate for MAS was higher in the study group as compared to international figures. Prognosis. It is an important cause of neonatal morbidity and mortality in otherwise healthy term and post-term infants, with a case fatality rate approaching 40% [3]. This is called meconium aspiration, and it usually happens in babies born on time or post-term after 42 weeks as opposed to premature infants. The first bowel movement a baby has is called meconium.
