Many patients with severe decubitus ulcers are difficult to aggravate if timely intervention and treatment are given at an early stage when symptoms appear. However, the problem is that we know very little about the characteristics of bedsores at different times, so below we will briefly introduce the bedsores and their characteristics at different times. In this period, patients have difficulty sleeping and eating, and the skin is under high pressure for a long time, and is eroded by sweat and urine day and night, which will affect the basic blood circulation and lead to the appearance of red spots and lumps. 2. Periodic bedsores If the pressure on the skin is not relieved in time, skin defects will appear immediately afterwards, which are commonly known as ulcers and blisters. 3.Stage decubitus ulcers and blisters will expand with continued high pressure and moisture until they are exposed deep in the skin and large areas of decaying flesh appear, and the patient’s body can be riddled with holes. 4.Stage decubitus ulcers Given the physical characteristics of decubitus ulcer patients, it is generally difficult to effectively control decubitus ulcers when the above-mentioned conditions occur, at which point skin tissue defects that are deeply visible to the bone gradually form. The above are the different periods of decubitus ulcers and their characteristics. I personally recommend that people receive open treatment with a combination of Chinese and Western medicine, which can effectively promote the healing of decubitus ulcers by clearing the wound, controlling infection, improving circulation, nourishing the wound surface, and removing decay and creating muscle.
