We reported two case studies of meconium aspiration syndrome (MAS) with pul
monary hemorrhage in which we applied surfactant lavage and replacement. Su
rfactant lavage and replacement of MAS with pulmonary hemorrhage appears to
be effective and safe adjunctive therapy. The relatively small replacement
doses of surfactant required may be attributed to surfactant lavage follow
ed by surfactant replacement. We suggest that surfactant lavage and replace
ment of MAS with pulmonary hemorrhage should be further investigated by a r
andomized controlled trial.
