The active surface of the dressing is coated with a cross-linked adhesive mass containing a dispersion of gelatin, pectin and carboxymethyl cellulose together with other polymers and adhesives forming a flexible wafer. In contact with wound exudate, the polysaccharides and other polymers absorb water and swell, forming a gel. The gel may be ...
The exact mechanism of action of silicone gel sheeting has not been fully studied. Currently, many proposed mechanisms explain the efficacy of such treatment, including the occlusion and hydration effect, increased body surface temperature, polarized electric charge, immunological effects, etc. [9] The occlusion and hydration effect is the most studied mechanism of action.
Therefore, this type of dressing is useful for wound with high amount of discharge and for wound with granulation tissue. Secondary dressings are not required. However, it requires frequent changing and is not suitable for dry wounds. Silicone is a common material that make up the foam. The foam is able to mold according to the shape of the wound.
Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]
Traumagel is an algae-derived gel that comes in a pre-filled syringe and requires no manual pressure on the wound to create a blood clot, according to the company.
Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
A synthetic adsorbable suture material. Braided synthetic adsorbable multifilament made of polyglycolic acid and coated with N-laurin and L-lysine, which render the thread extremely smooth, soft and knot safe. A synthetic adsorbable suture material. Monofilament synthetic absorbable suture, prepared from the polyester, poly (p-dioxanone ...
