Chlorhexidine-Impregnated Dressings and Prevention of Catheter-Associated Bloodstream Infections in a Pediatric Intensive Care Unit.

BACKGROUND

Bloodstream infections related to use of catheters are associated with increased morbidity and mortality rates, prolonged hospital lengths of stay, and increased medical costs.

OBJECTIVES

To compare the effectiveness of chlorhexidine-impregnated dressings with that of standard dressings in preventing catheter-related bloodstream infections.

METHODS

A total of 100 children were randomly divided into 2 groups of 50 each: a chlorhexidine group and a standard group. Patient care was provided in accordance with prevention bundles. Patients were followed up for development of catheter-related bloodstream infections.

RESULTS

Catheter colonization occurred in 4 patients in the standard group (8%) and in 1 patient in the chlorhexidine group (2%). Catheter-related bloodstream infections occurred in 5 patients in the standard group (10%) and in 1 patient in the chlorhexidine group (2%). Although more patients in the standard group had catheter-related bloodstream infections, the difference in infection rates between the 2 groups was not significant (P = .07).

CONCLUSIONS

Use of chlorhexidine-impregnated dressings reduced rates of catheter-related bloodstream infections, contamination, colonization, and local catheter infection in a pediatric intensive care unit but was not significantly better than use of standard dressings.
