• Impact of anti-microbial drain sponge dressing on total bacterial counts
at tracheostomy sites

Bacteremia is a common complication in tracheostomy patients with the causative organisms found in the trachea or on the skin. One study noted that administering prophylactic antibiotics did not produce any significant effect. 1

This prospective, open label, randomized, controlled case series evaluated an anti-microbial drain sponge* dressing's effect upon total bacterial counts. The control was a drain sponge dressing without an anti-microbial agent.

Ten subjects were randomized to either the study dressing or the control. Daily for 5 consecutive days, investigators collected semi-quantitative wound swab cultures of the stomal site and performed dressing changes. Targeting 6 bacterial isolates known to be prevalent in this study population, a CLIA-certified laboratory analyzed the culture results.

Compared to the control group, subjects randomized to the anti-microbial drain sponge dressing had a greater reduction in Methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Enterobacter cloacae, and Staphylococcus aureus bacterial counts. The absence of bacterial growth was also evaluated; the study group did not have any bacterial growth for a sum total of 11 days versus 6 days in the control group.

Study findings suggest that the application of an anti-microbial drain sponge dressing to tracheostomy sites could be an important adjunct in the control of bacterial colonization.
