Heiring C, et al. - Via obtaining gastric aspirate (GAS) from 72 infants, researchers assessed the accuracy of the new rapid point-of-care (POC) test for lung maturity. The method described in an accompanying article has been developed to improve the outcome of respiratory distress syndrome. The test enables surfactant delivery already at birth in infants with immature lungs and ensures that infants with mature lungs are not unnecessarily treated. Findings revealed that there is high sensitivity to the new improved spectroscopic lecithin-sphingomyelin method of lung maturity on GAS. The method is designed to be used at birth as a POC test and a spectroscopic prototype for bedside use has been developed. Clinical trials are planned for this new lung maturity test.
