Resumen

Introduction: The administration of parenteral infusates is a frequent intervention that is mistakenly considered innocuous, but require specific control measures. Objective: To evaluate the epidemiology of nosocomial pediatric bacteremias after implementation of a control program. Material and methods: The 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 fro m 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 fro m intravascular catheters. The proportion of contaminated parenteral infusions dropped fro m 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 Gramnegative 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 fro m developing countries.
