The initial clinical response to synthetic or natural surfactant is different and long-term complications from meta-analysis suggest that bronchopulmonary dysplasia and retinopathy of prematurity may be increased in infants given synthetic surfactant. It is possible that this is due to differences in the phospholipid composition of lung fluid following administration of these surfactants. Infants less than 32 weeks gestation with respiratory distress syndrome (RDS) were randomly assigned to receive either Exosurf, an artificial surfactant, or Survanta, a natural surfactant. Endotracheal or hypopharyngeal aspirates were obtained from these infants and from control infants who had normal lungs. The aspirates were taken prior to and up to 28 days following surfactant administration. The different phospholipids were separated by thin layer chromatography and expressed as a percent of total phospholipid measured. Infants with normal lungs had a higher proportion of phosphatidylcholine than those with RDS prior to treatment. The infants with normal lungs had a greater proportion of phosphatidylinositol in their lung aspirates than both treatment groups at 24 h. Infants in the Survanta group had a higher proportion of phosphatidylglycerol at 48 h than the group with normal lungs. No other differences were found in phospholipid composition up to 28 days. There were no major differences in the phospholipid profile in infants with RDS treated with either Exosurf or Survanta. In conclusion, neither the clinical differences initially seen between infants treated with either Exosurf or Survanta, nor the long-term outcome could be explained by the phospholipid composition of serial samples of lung aspirates. |
