Decubitus ulcers, also known as pressure ulcers and pressure sores, are caused by long-term pressure on local tissues and the occurrence of continuous ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. Decubitus ulcers are a common problem in rehabilitation treatment and care. According to the literature, about 60,000 people die each year from pressure sore complications. Decubitus ulcers are not incurable and can be steadily rehabilitated with proper wound management. Many patients have deepened and expanded their wounds due to a lack of knowledge about bedsores or due to improper treatment, but in fact bedsores are essentially wounds that are not as difficult to dispose of in the correct way as one might think. 1, distinguish the severity of decubitus ulcer wounds First, distinguish the severity of decubitus ulcer wounds. For severe necrotic decubitus ulcers and difficult decubitus ulcers, it is necessary to go to a professional skin ulcer department for debridement treatment and comprehensive treatment, which includes surgical removal of black scabs, excision of necrosis, dissection of flesh, wound cleaning, etc. It is important to recognize that home care for severe decubitus ulcers is difficult to achieve, and delays such as delays may lead to more and more severe injuries. Severe. 2.Clear wound treatment according to the wound situation Secondly, after the wound is cleared and treated, the wound is transformed from a necrotic wound to a clean wound, and from a semi-closed wound to an open wound. At this time, the unfavorable factors that hinder the growth of granulation are eliminated and the trauma environment is well improved, and with the care of negative pressure drainage and topical ointments, the growth of granulation tissue can be accelerated. 3.Multiple treatment methods combined Some difficult wound problems, in the middle and late stages of healing, may have slow epithelial, not closing and other problems, need to cooperate with surgical suture, skin pulling, flap grafting and other methods to achieve the effect of wound closure, so as to shorten the recovery cycle of the wound. 4, taking into account the whole body condition Finally, decubitus ulcer care is never just about local wound treatment, but also about the whole body indicators, especially the nutritional status of the patient. Many patients over-consume their bodies due to the effects of the primary disease, coupled with insufficient nutritional intake, and at this time, it may be necessary to cooperate with intravenous infusion to supplement nutrition and improve the physical condition comprehensively. In addition, family members must do a good job of protecting against decubitus ulcers and preventing decubitus ulcers from occurring in other parts of the body during the care process, and do the following in daily care: Pressure prevention – it is best to turn over once every two hours, with soft clothing padded at the bony prominence, and also with decubitus inflatable mattresses or triangular turning pads to help reduce pressure. Cleanliness – keep the skin clean and dry, avoid being soaked by urine and feces, and rub the whole body at least once a week. Anti-friction – keep the bed sheets clean and dry, and keep the sheets flat and wrinkle-free. Enhance nutrition – Give a high protein and vitamin diet to improve the general condition of the patient with decubitus ulcer.
