The experience of Drs Kilbride and Daily concerning the survival and morbidity of infants with birth weights less than 800 g appears to be very similar to our own. Their reported survival between 1980 and 1990 for infants between 701 and 700 g birth weight demonstrates the identical improvement over time which we describe down to at least 500 g. Most of the increased survival at the University of Washington attributable to surfactant therapy has occurred after 1990.
