Introduction: Healthcare-associated infections (HAI) are those corresponding to any general or localized infection occurring as a consequence of healthcare, and that was not present or incubating at the time of admission. Objectives: To determine the rates of a) ventilator-associated pneumonia (VAP); b) bloodstream infection associated with central venous catheter (BSI/CVC); c) urinary tract infection associated with indwelling urinary catheter (UTI/IUC); and d) microorganisms isolated in each locale.   Materials and Methods: We conducted an observational, descriptive, cross-sectional study from January to December 2011 of patients with infections associated with invasive procedures hospitalized at our multidisciplinary pediatric intensive care unit. we used a system of active and selective surveillance, using definitions standardized in the National Infection-control Program of Paraguay and the U.S. National Healthcare Safety Network (NHSN). Results: A total of 9 VAP were reported, showing a rate of 9/1000 days of ventilation. Cultures showed: Acinetobacter sp. (1), K .pneumoniae (ESBL+) (1), E. cloacae (1), Candida albicans (1), negative cultures (4), not cultured (1). We observed 4 BSI/CVC, with a rate of 2/1000 days of central venous catheter. Microorganisms isolated were: A. baumanii complex (1) Acinetobacter sp (1), Staphylococcus coagulase negative (1), and Candida albicans (1). We identified 3 UTI/IUC, with a rate of 3/1000 days of IUC. Microorganisms isolated were K. pneumoniae (ESBL+) (1) and Candida albicans (2). Conclusions: We observed that VAP was the most common infection in the procedures under surveillance, followed by UTI/IUC and BSI/CVC, with gram-negative bacilli predominating.
