Dressing which provides an impermeable barrier against bacteria, including MRSA (in-vitro), to reduce the risk of surgical site infection. The molecular structure gives a high moisture vapour transmission rate and allows unwanted moisture to transpire. Rounded corners reduces lifting or snagging, helping the dressing to stay in place longer. Absorbent pad allows lateral spread across the pad to maximise absorbency, reducing the risk of skin maceration and minimising the number of dressing changes. Waterproof film allows patient to shower with the dressing in situ.
