What is a wound?
A wound occurs when tissue or organ damage occurs. Depending on the course of healing they can be both acute and chronic and have four stages of healing. Chronic wounds lag behind in one of these healing phases, most often the second, inflammatory phase, and do not heal within the prescribed period and in the shortest period of 6 weeks. Treatment of chronic wounds is very complex and long-lasting and wound healing depends on many factors such as the cause (venous ulcer of the lower leg about 80%, 5-10% ischemic lower leg ulcers, neuropathic, diabetic ulcer), and the general condition and age of the patient or therapy which he takes.
How to treat a wound?
The first step is to review and assess patients (associated diseases, taking medications that could slow wound healing, the patient’s nutritional status, the presence of inflammation, etc.) and treating the underlying disease or condition that led to the chronic wound.
The second step is to assess the wound – determine the location and appearance of the wound, size, depth, secretion, the presence of signs of inflammation, etc.
Methods of wound healing
This removes dead tissue as well as a layer of bacteria found on the surface of the wound that prevents normal wound healing. Once a clean, slightly bleeding surface is obtained based on the findings, it is decided which type of therapy will be applied to the wound. The method of further treatment depends on the wound itself.
Swab if there are inflammatory signs, biopsy for atypical wounds.
Modern coverings enable moist wound healing, that is, they additionally moisturize a wound that is dry and absorb secretions in wounds with secretions. They also isolate the wound from external influences, and with the help of antimicrobial substances prevent the growth of bacteria. In wounds where necrotic or fibrin deposits are not completely removed under the dressing, hydrocolloid gels are used for autolytic degradation. The type of dressing applied depends on the wound itself and the stage of wound healing.
(NPWT – Negative Pressure Wound Therapy) is used for wounds with increased secretion. The goal is, in addition to removing secretions and cleansing the wound, to encourage the development of granulation tissue, which accelerates wound healing by up to 4 times. The therapy is applied for an average of 7-15 days with very good results. Application technique and professional application are important, otherwise additional tissue damage may occur.
PRF (Pletelet Rich Fibrin) is obtained by centrifuging the patient’s blood. It is in the form of a gel and as such is applied to a previously cleansed wound. The principle of action on wound healing is that the release and activation of platelets leads to the secretion of growth factors that stimulate the growth of cells involved in wound healing. The advantages of applying this therapy in wound healing are that it doubles the speed of healing, reduces pain, and there are no allergic reactions.
This technique is used to reduce the accumulation of fluid (edema) in the subcutaneous tissue, which is one of the main causes of non-healing of venous ulcers.
