Surveillance of Infections Associated With Intravenous Catheters in Dogs and Cats in an Intensive Care Unit

Abstract

Positive catheter-tip culture rates and risk factors associated with bacterial colonization of intravenous (IV) catheters were assessed in dogs and cats. Aerobic and anaerobic bacterial cultures were performed on 151 catheters, and 24.5% were positive. Of the positive cultures, 46.0% grew Enterobacter spp. The type of catheter used, blood sampling through the catheter, the type of IV infusate administered, the duration the catheter was in place, the catheter location, complications with the catheter, and the final outcome of the animal were not associated with an increased risk of a positive bacterial culture from the catheter tip.
