Odour-absorbing dressings.

This study uses an objective test system that compares the ability of different dressings to prevent the passage of a volatile amine when applied to a wound model under simulated 'in-use' conditions. Five dressings containing activated charcoal were tested by this method, and a low-adherent absorbent dressing was used as a control. Results demonstrate clear differences in the ability of the products to contain the test solution and prevent the loss of the volatile diethylamine into the surrounding air. Products which combine a physical absorbent with a charcoal component show enhanced performance.
