Wounds that heal more than two weeks after a burn and scald, doctors recommend wearing elastic sleeves or bandages to prevent and reduce scars. So what is stress therapy and what is the mechanism of treatment?

Pressure therapy is an elastic cover made of elastic fabric at the corresponding part, such as a face mask, elastic socks, etc., to continuously compress the burned and scalded healing area to achieve the purpose of preventing and reducing skin contraction and marginal scar hyperplasia.

The mechanism of histopathological changes of compression therapy is not clear. It may be that stress causes ischemia, activates tissue metabolism, and increases collagenase activity. Due to local hypoxia-ischemia, the number of capillaries is reduced, the blood supply of scar tissue is reduced, the intracellular oxygen partial pressure is reduced under hypoxia, and mitochondrial function is even reduced. Morphological changes occurred at the same time. Such as mitochondrial swelling, vacuole degeneration and so on. In this way, the mitochondria that are mainly used for cell biological oxidation cannot release energy well in a series of oxidative phosphorylation processes, resulting in the inhibition of fibroblast proliferation, and finally degeneration and necrosis, and the function of generating collagen fibers and matrix is greatly reduced. As a result, the scar becomes thinner and softened. The collagen fibers can be arranged in parallel and the helical collagen structure can be rearranged to soften and flatten the scar.

From the time of wound healing, stress treatment should be applied. Early pressure treatment can control scar hyperplasia, promote scar maturation and softening, and prevent joint contractures and deformities.
