Resumen

Objective: To determine the rate of Gram-negative rod contamination of in- use intravenous solutions and injection ports in pediatric patients. Methods: During non-epidemic periods, eight pediatric wards in Mexican hospitals were studied. Qualitative cultures were taken from the surface of injection ports and from intravenous solutions in use in pediatric patients younger than 2 years. 750 infusion systems from 728 patients were cultured. Results: The rate of contamination for intravenous solutions was 2.4% (18/750; CI 95%: 1.3% to 3.5%) and 3.2% (24/750; CI 95%: 2.1 % to 4.3%) for injection ports. Enterobacteriaceae predominated; in four cases the organisms isolated from the port matched those in the solutions (Klebsiella spp. and Enterobacter sp.). The rate of contamination for solutions mixed in the wards was 5.1%, against 1.3% of those not mixed (χ² = 9.19, p < 0.01). Discussion: Contamination of parenteral solutions is not a rare phenomenon and could be related to inappropriate preparation of intravenous solutions and medications, as well as the contamination of injection ports. In hospitals working with similar standards, monitoring the sterility of intravenous solutions could contribute to reduce the rate of nosocomial bacteremia.
