Decubitus ulcers, also known as pressure sores, are caused by long-term localized pressure on the body that impedes blood circulation and causes ischemia of the skin and subcutaneous tissues, resulting in blisters, ulcers or gangrene. Generally speaking, long-term bed-ridden, frail, turn over inconvenient and limb sensory retardation easy to suffer from bedsores, clinically seen in the following three categories of patients: 1, cerebral infarction resulting in paraplegia, long-term bed-ridden patients, coma and paralyzed patients; 2, bed-ridden, frail patients; 3, long-term fixation of bone fracture or bed-ridden patients. What are the hazards of bedsores 1, skin and deep tissue damage: bedsores have a high incidence rate, rapid development of the disease process, difficult to cure and easy to recur after treatment. Some patients have bedsores that are only the size of a dollar coin at the beginning, but due to improper treatment, they develop into serious bedsores that are the size of a bowl in just a few months. The skin tissue may only show erythema or pallor at the initial stage, followed by dark purple color and blisters, and then serious development, ischemic necrosis of the subcutaneous fat layer and muscle tissues occurs. Once this stage is reached, the treatment measures are quite tricky, and the treatment time for recovery is mostly in 3 months or even longer. Older people have poor repair ability due to the aging of the skin, making it extremely difficult for bedsores to heal. Long-standing decubitus ulcers can easily lead to a series of complications such as sepsis, osteomyelitis and hypoproteinemia, which not only make the treatment of the original disease more difficult, but can even accelerate the patient’s death in some cases. Therefore, decubitus ulcers are an important reason for the increase of death rate of elderly patients. 2, septicemia: bedsore treatment is not timely, necrotic tissue debridement is not complete, easily lead to concurrent infections of the wound tissue, the infecting bacteria are complex and diverse, and there may be a variety of antibiotic-resistant multi-drug-resistant bacteria, resulting in increased difficulty in treatment, Deji Hospital bedsore center has admitted a patient, the wound culture of “A. baumannii”, belongs to multi-drug-resistant bacteria, drug-resistant bacteria, and the patient has been admitted to a bedsore center, and the wound culture “A. baumannii”. The patient was hospitalized in our hospital with symptoms such as high fever, poor appetite, intolerable pain in bedsore wounds, hypoproteinemia, etc. After checking the blood leukocytes increased significantly, the heartbeat was more than 90 beats/min, the body temperature was persistently higher than 38.3℃, and there was obvious septicemia manifestation, which brought great difficulty to the treatment. 3, osteomyelitis: osteomyelitis refers to purulent bacterial infection of bone marrow, bone cortex and periosteum caused by inflammatory diseases, mostly caused by hematogenous, decubitus ulcers infected trauma tissue invasion of bone tissue, resulting in bone destruction, coupled with the presence of septicemia, the bacteria and toxins for a long period of time, resulting in bone marrow inflammation. Repeated episodes are common in clinic, which seriously affects physical and mental health and labor ability. Acute osteomyelitis starts with high fever and local pain, and when it turns into chronic osteomyelitis, there will be ulceration, pus flow, dead bone or cavity formation, and severe patients are often life-threatening, and sometimes they have to take emergency amputation, which will lead to lifelong disability of the patients. 4, hypoproteinemia: decubitus ulcers are often serious complications caused by other diseases, due to the existence of the patient’s primary disease, activity difficulties, poor diet, decubitus ulcer infections, sepsis, hyperthermia and other factors leading to the patient’s hypoproteinemia, the whole body tissue edema, decubitus ulcers wounds oozing, long-lasting edema resulting in ischemia of the tissue, recovery is slow. 5, aggravate the primary disease: the above adverse factors superimposed, will cause patients with multiple organ function problems, if the patient’s original liver, lung, heart disease, can aggravate the dysfunction of these organs, acid-base balance imbalance, electrolyte disorders, and even liver failure, heart failure, sudden cardiovascular and cerebrovascular accidents and so on. How to prevent decubitus ulcers in the elderly First of all, we should be diligent in turning over, generally bedridden patients turn over once every 1 to 2 hours, if the skin is found to be red, then it should be turned over once every hour, left, right side lying, lying down, prone position alternately, for the unstable condition, does not apply to change the position of the person, the application of the air cushion bed, the use of inflatable and deflatable function of the alternate replacement and massage of the pressurized parts, and at the same time, reduce the pressure parts of the shear force and the pressurization of the time. The next step is to correctly implement skin massage. Secondly, skin massage should be implemented correctly, caregivers under the guidance of professionals, the elderly back, sacrococcygeal, hip joints and other parts of the continuous massage protection. “The movements must be gentle.”
