ABSTRACT
Objective. To determine the rate of contamination of intravenous
solutions and injection ports in pediatric patients.
Material and methods. During non-epidemic periods,
eight pediatric wards in Mexican hospitals were studied. Qualitative
cultures were performed from the surface of injection
ports and from intravenous solutions in use in pediatric patients
younger than 2 years, culturing 750 infusion systems
from 728 patients.
Results. The rate of contamination of intravenous
solutions was 2.4% (18/750; CI 95%: 1.3% to 3.5%)
and for injection ports it was 3.2% (24/750; CI 95%: 2.1 % to
4.3%). Enterobacteriaceae predominated; in four cases the organisms
isolated from the port and from the solutions were
coincident (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 (χ
2 = 9.19, p ‹ 0.01).
Discussion.
Contamination of parenteral solutions is not a rare
phenomenon and it could be related to inappropriate practices
in the preparation of intravenous solutions and medications
as well as the contamination of injection ports. In hospitals
working with standards similar to those reported here,
the monitoring of sterility of intravenous solutions could contribute
to reduce the rate of nosocomial bacteremia.
