Is the lung damage from meconium aspiration permanent?

No: Meconium aspiration, per se, is uncommon, and many cases of so-called meconium aspiration are simply other forms of respiratory distress noted in newborns who also passed meconium prior to delivery. True meconium aspiration does cause acute lung injury but most, if not all, cases heal completely within days to weeks.

No: Residual lung problems are rare but include symptomatic cough, wheezing, and persistent hyperinflation for up to 5-10 yr. The ultimate prognosis depends on the extent of CNS injury from asphyxia and the presence of associated problems such as pulmonary hypertension.
