Comparison of dry and wet wound environment
Traditional wound treatment, dry healing environment
Disadvantages:
(1) The wound is dehydrated, scabbed, and is not conducive to epithelial cell crawling
(2) The patient's pain
(3) Loss of biologically active substances and slow healing
(4) Adhesion of the dressing wound, and mechanical damage again when the dressing is changed
Wet Healing Environment Theory
advantage:
(1) Speed up the migration of epidermal cells
(2) Keep moist, which is conducive to the dissolution of necrotic tissue and fibrin
(3) Maintain and promote the release of various biologically active factors
(4) It is beneficial to cell proliferation, differentiation and migration, and accelerates the formation of granulation tissue
(5) Pain relief
(6) The dressing does not adhere to the new granulation tissue, avoiding mechanical damage when changing the dressing.
Advantages of Polyurethane Foam Dressings
1. It can quickly absorb and lock the exudate in large quantities, maintain the moist environment of the wound, and prevent the surrounding normal skin from macerating.
2. After absorbing the exudate, it expands inward, making it more compliant with the wound surface; the foam pad that keeps the wound locally moist and soft can evenly disperse the pressure.
3. It does not adhere to the wound to avoid mechanical damage when changing the dressing; even under the pressure bandage, the performance of absorbing exudate is still good.
