MPPT works by absorbing the exudate, pumping it to the enlarged surface of the MPPT layer from where it evaporates. Occlusive dressings interfere with the evaporation and are, consequently, not advised. Protective bandaging is usually occlusive and, therefore, not recommended.
If protective padding is absolutely necessary, a plain, standard absorbent, foam dressing, e.g. Allevyn Non-Adhesive, without any active components, e.g. silver, should be placed on top of the MPPT layer. Standard procedures for protective dressings should then be followed. It can be left on for 1-3 days – as is usual procedure for this type of dressing.
