Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Negative-pressure wound therapy (NPWT): [41] [42] A unique type of dressing which consists of a foam dressing surrounded with an airtight film and then connected to power-assisted vacuum suction, creating a negative pressure environment over the wound. This negative pressure environment is thought to promote formation of granulation tissue and ...
The intermittent vacuum therapy (IVT) is a treatment conducted in case of venous and arterial issues as well as in rehabilitation (after sports injuries [1] and vascular complaints). With the aid of normal and low pressure , it should enable to control venous reflux, enhance lymphatic flow [ 2 ] and improve blood flow in periphery and muscles.
An increasingly common aid to both pre-operative wound maintenance and post-operative graft healing is the use of negative pressure wound therapy (NPWT). This system works by placing a section of foam cut to size over the wound, then laying a perforated tube onto the foam. The arrangement is then secured with bandages.
