The gel may be designed to drain, or to remain within the structure of the adhesive matrix. [4] The moist conditions produced under the dressing are intended to promote fibrinolysis, angiogenesis and wound healing, without causing softening and breaking down of tissue. The gel which is formed as a result of the absorption of wound exudate is ...
The dressing should be changed and the wound irrigated with normal saline at least twice each day. [4] In addition, it is recommended to administer an antibiotic active against staphylococci and streptococci, preferably vancomycin when there is a risk of methicillin-resistant Staphylococcus aureus .

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 ]
However, this dressing is not suitable for dry wounds, third degree burn wound, and deep wounds with exposed bone. It also requires secondary dressing because wounds can quickly dry up with alginate dressing. [9] Hydrofiber dressing: Made up of sodium carboxymethyl cellulose, hydrofibers can absorb high amounts of wound discharge, forming a gel ...
Negative pressure wound therapy device. 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.
In the form of fibres trapped in a wound, alginate is readily biodegradable [15] and can be rinsed away with saline irrigation. Subsequent removal therefore, does not destroy granulation tissue, making dressing change virtually painless. The ease of biodegradation is exploited in making alginate sutures used in surgical wound closures.

An occlusive dressing is an air- and water-tight trauma medical dressing used in first aid.These dressings are generally made with a waxy coating so as to provide a total seal, and as a result do not have the absorbent properties of gauze pads.
