The single use portable NPWT dressing used for outdoor (OPD) patients is PICO (Smith and Nephew
Healthcare, Hull, United Kingdom) that requires fewer dressing changes and is an adjuvant therapy to
[5]
hasten wound healing. PICO is better accepted by OPD patient with reduced financial burden .
C. Depending on sealing of the device, NPWT may be classified as:
1. NPWT with occlusive dressing: such dressings provide moist healing environment with enormous
capacity to remove soakage. Examples include VAC and LAD. Moist healing becomes more effective in
[3,4]
intermittent negative pressure regimen, such as in LAD .
2. NPWT with semi-occlusive dressing. Such dressings, apart from negative pressure, provide wet to dry
[4]
environment, and are effective in wounds with relatively small amount of soakage. An example is SAD .
D. Depending on area of dressing, NPWT may be classified as:
1. Small area dressing.
2. NPWT over a part of a region of the body, e.g., foot.
3. NPWT over a region of the body, e.g., inferior or superior extremity.
4. Separate NPWT over multiple regions of the body, e.g., both limbs separately, one upper limb and one
lower limb, etc.
5. Extra large and complex NPWT, e.g., upper limb and adjacent chest.
6. Whole body dressing, e.g., in extensive burn areas.
7. Special area NPWT, e.g., perineum, face and scalp, or over area with external fixator.
