Abstract With the advent of surfactant replacement therapy, there is an increasing need for a rapid test of predicting the development of respiratory distress syndrome (RDS). We evaluated the clinical usefulness of the stable microbubble (SM) test in predicting the development of RDS by comparison with other tests in amniotic fluid samples obtained within 12h before delivery from 40 pregnancies between 23–35 weeks of gestation. These tests included the lecithin/sphingomyelin (L/S) ratio, disaturated phosphatidylcholine/sphingomyelin (DSPC/S) ratio, concentrations of lecithin, DSPC, and surfactant-associated proteins A and B, C (SP-A, SP-B,C). The cut-off value of each test for predicting RDS was determined at a point of maximum diagnostic accuracy. The overall diagnostic accuracy of the SM test was similar to that of other tests. However, both the SM test and the SP-B,C concentration had positive predictive values of 100%. We conclude that the rapid (〈10 min) and reliable information obtained by this test should encourage its use in defining a population of neonates with surfactant deficiency in a multicentre trial of prophylactic surfactant therapy.
