Hyaline membrane disease: prognostic factors and medium-term follow-up

One hundred and twenty two cases of severe hyaline membrane disease are reported. 68 of them survived (57%). Adverse clinical, radiological and laboratory factors, and their effects on the early mortality rate, are analysed with particular reference to the referring centers, delay in admission, transport and the critical state of most infants on admission. The follow-up of 29 survivors treated before 1974 has been examined with reference to birthweight and assisted respiration. Four (30%) of the twelve infants with birthweights below 2000 g had major neurological sequelae. Only two out of the 17 babies with a birthweight over 2000 g had minor mental disturbances.
