Use of semipermeable polyurethane membrane for skin graft dressings.

The use of semipermeable polyurethane membrane (Op-site) for skin graft donor-site dressings is now well-accepted. We have used Op-site for skin graft coverage in 25 patients with good results. The dressing modality is not only easy to do, even in anatomically difficult areas, but it also maintains a moist environment, allows daily graft observation, and provides a barrier for exogenous bacteria.
