Smith & Nephew’s Opsite Post-Op is a revolutionary post-operative dressing combining a high Moisture Vapour Transmission Rate (MVTR) film and the cushioning and absorbency of a low adherent pad together with an easy application carrier system. The hydrophilic polyurethane film on Opsite Post-Op has REACTIC* properties that ‘switch on’ in the presence of moisture allowing any excess to transpire into the atmosphere.
