[Survival analysis of acute pyogenic meningitis in children].
In order to determine the survival curves of lethality in acute bacterial meningitis (ABM) in children, we reviewed the charts of all patients admitted to the Hospital Couto Maia from January 1990 to December 1992. The Kaplan-Meir analysis was used to compare the survival rate and hospitalar permanence of patients with identified pathogens with those whose bacteria were not determined. The same analysis was used to compare the curves of the three most frequent agents. Statistical difference between the identified and nonidentified groups was not observed. The analysis of the three curves shows that the first 24 hours were responsible for the most elevated lethality rate. When the curves are compared, it is clear that S. pneumoniae has the most important intrahospitalar lethality and N. meningitidis the most benign evolution. We conclude that efforts have to be made to determine which variables are related to prognosis of ABM at the first day of hospital admission.
