title: A comparison of the in-vitro antibacterial and complement activating effect of 'OpSite' and 'Tegaderm' dressings.
abstract: Two readily available semipermeable polyurethane dressings, 'OpSite' and 'Tegaderm', were tested for their in vitro ability to kill potential bacterial pathogens and activate complement C3. In bacterial killing tests, 'OpSite' was superior to 'Tegaderm' and in addition only 'OpSite' activated C3. It is concluded that in the practical situation, 'OpSite' could well confer a greater margin of safety.
