RESUMO
INTRODUCTION: Nosocomial infection (NI) is a common complication in paediatric critical care units (PICU), with an associated mortality up to 11%. OBJECTIVE: To describe NI epidemiology in the national PICU. To initiate an standard NI control measures to obtain paediatric incidence rates. PATIENTS AND METHOD: Multicentre prospective study from 1 to 31 march 2007. Centre Disease Control diagnosis and methodological criteria were used. It was specially analyzed NI related to invasive devices: central venous catheter (CVC), mechanical ventilation (MV), urinary catheter (UC). RESULTS: There were recruited 300 patients from 6 PICU, with 17 NI episodes in 16 patients (5,3% from admitted). NI rates resulted in 13,8 infections/1000 patients-day. Middle age from infected patients was 2,31 years (± 3,43), 9 males. Risk factors were found in 7 cases. NI location was: catheter-related bloodstream infection in 7 patients (6,7/1000 days CVC), ventilator associated pneumonia in 4 (9,4/1000 MV days), urinary-tract infection associated with UC in 4 (5,5/1000 UC days), one case of primary bloodstream infection and one surgical site infection. Isolated microorganisms were: 9 gram negatives bacillus, 4 Candida, 2 plasmocoagulase negative staphylococcus, 1 Haemophilus and 1 Staphylococcus aureus. Seven isolations were resistant microorganisms. There weren't any died related to NI. CONCLUSIONS: NI epidemiology was similar to published data in our near countries. NI surveillance, with a standardized method of analysis is essential to the NI correct manage.
