Wounds healed more than two weeks after burns, doctors recommend wearing elastic sleeves or elastic bandages to prevent and reduce scars. So what is the pressure therapy? What is the treatment mechanism?

Pressure therapy is the elastic cover of the corresponding part made of elastic fabric, such as face mask, elastic socks, etc., which continuously presses the burned and scalded healing area, so as to prevent and reduce the skin graft area and marginal scar hyperplasia.

The mechanism of histopathological changes of pressure therapy is not yet clear. It may be that pressure causes ischemia, activates tissue metabolism, and increases collagenase activity. Due to local hypoxia and ischemia, the number of capillaries is reduced, the blood supply of scar tissue is reduced, the partial pressure of oxygen in the cells is reduced under hypoxia, and the function of mitochondria is reduced or even stopped. At the same time morphological changes occurred. Such as mitochondrial swelling and vacuolar degeneration. In this way, the mitochondria that are mainly used for cellular biological oxidation cannot release energy in a series of oxidative phosphorylation processes, so that the proliferation of fibroblasts is inhibited, and finally degeneration and necrosis occur, and the function of generating collagen fibers and matrix is greatly reduced As a result, the scar becomes thinner and softer. The collagen fibers can be arranged in parallel, and the spiral collagen structure can be rearranged, thereby softening and flattening the scar.

Start from the basic wound healing, that is, stress treatment should be performed. Early pressure therapy can control scar hyperplasia, promote scar maturation and softening, and prevent joint contractures and deformities.
