Current Wound Management Challenge

Problem: Wounds have varying degrees of exudate, transudate, and plasma from dry to wet. The clinician must cleanly debride the wound, close it and manage wound healing in a moist but not wet environment to achieve optimal results.

Solution: A single dressing that possesses all the properties reported to be needed for a sophisticated primary dressing and in addition has ‘variable porosity’ controlled by the clinician from zero to what the wound requires. Such a device enables the clinician to move the fluid exuding from the wound through the primary dressing into an absorbent secondary dressing without disturbing the kinetics of healing. This represents A World of Difference in the art of wound management - PermeaDerm dressing.

Benefits: Many. This form of therapy addresses three objectives in healthcare – improved care, less risk, and lower costs. Current therapies require painful primary dressing changes that interrupt healing, add risk of infection, and may require narcotics to comfort the patient which can extend the length of treatment. With PermeaDerm a clinician can set optimal porosity for the wound being managed, avoid dressing changes, and improve optimal healing times. PermeaDerm is less expensive, and because it has a two year shelf-life at room temperature, it is less expensive to manage and creates less waste.

Variable Porosity

PermeaDerm dressings are a great benefit to clinicians and patients alike due to their “variable porosity”. Variable porosity allows for the pore size of the dressing to be essentially zero with no stretch applied to the dressing (which is the relaxed mode) to a higher porosity (proportional to the stretch applied by the clinician).

The pores of other dressings are fixed in the open position during the manufacturing process; i.e. the silicone is cured while the pore is open. In contrast, the pore (puncture/slit/hole) in PermeaDerm dressings is made after the silicone component has been cured and remains closed until stretched perpendicular to the orientation of the slits.

In products without variable porosity, pores can be slightly expanded in size if the membrane is able to stretch, but cannot decrease in size; which can lead to ‘punctate scarring’ when employed on superficial scald burns. Aesthetically punctate scarring is unacceptable especially on the face and hands.

PermeaDerm Burn dressing can be used without stretching on the face and hands and no punctate scarring is expected. Why? Punctate scarring can be observed when the wound is covered with a membrane containing open pores. In the case of PermeaDerm dressings (Burn or Chronic) used in the relaxed mode the entire wound will be uniformly and continuously covered with a thin silicone membrane.
