Introduction: The administration of parenteral infusates is a frequent intervention that is considered innocuous; moreover, the risk of this procedure which offers a direct access to the bloodstream is minimized.
Objective: To evaluate the epidemiology of nosocomial pediatric bacteremias after implementing a control program.
Methods: Analysis of pediatric bacteremias was made in 3 periods: 1) 1990-1992, prior to establishing strategies to avoid contamination of parenteral infusions; 2) 1996, the phase after establishing these strategies; and 3) 2005-2006, the recent situation in the hospital.
Results: The proportion of gram-negative rods isolated in blood cultures dropped from 82.9 to 35.1% (p = 0.004) during the 17-year study period. There was no significant difference in the proportion of gram-negative rods isolated from intravascular catheters. The proportion of contaminated parenteral infusions dropped from 22.2% to 0.4% (p < 0.001).
Discussion: The strategies established to avoid the contamination of parenteral infusions were associated with a reduction in the proportion of gram-negative rods in blood cultures, although the proportion is still higher than that in developed countries, probably related to catheter contamination. We suggest establishing similar strategies in other hospitals from developing countries.
