What are cavity lesions and how to treat them?

There are many reasons why wounds do not heal clinically, one being the case of a large hole under the wound. Pathologically, cavities are formed by necrosis of the lesion, liquefaction through the bronchi and the introduction of air.

Cavity injuries are very deep wounds involving the subcutaneous, fascial, tendon, and muscle planes. If the wound cavity is not treated effectively, it will not only affect the wound healing, but also cause infection or maceration due to excessive exudation, and in severe cases, subcutaneous fluid or fat liquefaction. Often, these wounds are the result of surgical dehiscence, trauma, or chronic ulcers.

Ways to promote wound healing include intravenous anti-infective therapy, oral or eating high-protein foods, and changing dressings to absorb exudate from infected wounds.

In the process of wound healing, once a cavity is formed, it means that the local tissue may be accompanied by chronic inflammation or fat liquefaction. The necrotic tissue should be removed in time, and the dressing should be packed to make the drainage smooth, so that new granulation can grow locally.

In order to speed up and improve the healing process of hollow wounds, a solution is formed through a reasonable combination of dressings to form a microenvironment with appropriate humidity for the injured area and promote the growth of cells and tissues. It is also one of the most important factors in the treatment of chronic injuries. All chronic wounds can be contaminated with bacteria, whether they are superficial or present in deeper areas, and when bacteria proliferate, they produce microcolonies and form biofilms.

Therefore, it is necessary to use a suitable advanced wound dressing (alginate dressing) for the treatment of hollow wounds. Once in contact with the exudate, the dressing forms a gel that integrates with the wound implant. At the same time, the gel strength makes the dressing strong enough to be completely and easily removed from the cavity when changing the dressing.

The main advantages of Longterm Medical's alginate dressings are:

1. Effective drainage of exudate, the wound bed is always clean, and the risk of leakage and maceration is greatly reduced.

2. Prevent pathogens, add Ag+, through the tiny crystals of silver, contact with exudates, reduce the concentration of bacteria in biofilm, prevent and limit the formation of biofilm.

3. Economical and convenient, the dressing can be placed for a long time without changing the dressing, and the duration varies according to the wound condition and patient characteristics, which can greatly save the cost of the dressing.

4. Anti-inflammatory and hemostasis, sodium ions and calcium ions in dressings play a role in wound care in ion exchange.
