RESUMO
OBJECTIVE: The authors evaluate the therapeutic efficacy of two antibiotic schedules, ceftriaxone alone and the combined use of ampicillin and chloramphenicol, in the treatment of septic children with purpuric presentation.METHODS: A randomized open clinical trial was conducted including septic children with purpuric presentation treated at a pediatric intensive care unit from April 1988 to June 1992. All cases with systemic purpura standing for less than a week were included in one of two groups, except for those recently hospitalized or with previous hemorrhagic disturbs. Patients in group A received ampicillin and chloramphenicol and those in group B were given ceftriaxone. Quantitative parameters were adopted to compare the efficacy of the two antibiotic schedules: sensitivity of bacteria isolated at blood and liquor cultures, complications, therapeutic procedures, period of hospitalization, and sequelae.RESULTS: 19 cases were included in the group A and 16 in group B, both homogenous on clinical-laboratorial aspects. The parameters evaluated did not show different efficacy between the two antimicrobial schedules tested, except for the number of complications observed during hospitalization, which was higher among the children that received ampicillin and chloramphenicol. The overall mortality for the patients treated was 13.8%, excluded the undernourished. CONCLUSIONS: The authors verify similar clinical therapeutic efficacy with the combined use of ampicillin and chloramphenicol or ceftriaxone, as observed previously. It must be pointed that the number of complications detected during hospitalization were higher in the group that received the combined antibiotic schedule. Low mortality in the present study may be attributed to the early diagnosis and therapeutic measures adopted at the pediatric intensive care unit.
