Definition of pressure ulcer noun explanation, what is pressure ulcer noun explanation

Pressure ulcers, also known as pressure ulcers and pressure ulcers, are caused by long-term pressure on local tissues of the human body, resulting in blood circulation disorders, or necrosis of deep tissues. Pressure ulcers are divided into four stages, the first stage is **complete, and the local ** tissue is red under pressure for a long time, and this red does not fade; The second stage is the first damage to the dermis, and the common manifestations are superficial ulcers and blisters; Stage 3 means that the ** tissue and subcutaneous tissue are damaged, but the bones, tendons and muscles are not exposed; Stage 4 is not only ** and subcutaneous tissue lesions, but also injuries, his muscles, bones, and tendons are exposed, and at this time, sinus tracts are formed, and even there is rotten flesh on the wound, as well as black eschar.

Pressure ulcer is a common clinical complication, which is more likely to occur in patients with long-term bed rest, spinal cord injury, chronic neurological diseases, physical weakness, etc., which not only affects the disease, but also leads to infection, bleeding, disability, septicemia and other diseases, which not only brings inconvenience to patients in daily life and mobility, but also causes significant mental and psychological effects on patients. The prevention and treatment of pressure ulcers can effectively reduce the pain of patients and shorten the time of patients, which is very important for pressure ulcer patients.

Pressure ulcer prevention. 1.** Examination and care.

Regularly check the whole body, especially the bony protrusions, keep them clean and dry, and pay attention to whether there are signs of tissue damage, such as redness, blisters, abrasions and swelling, etc., and deal with injuries in time.

2.Reduces friction.

Keep the sheets dry, tidy, flat, and free of debris, pay attention to checking and cleaning at any time, change the sheets regularly for the patient, and try to lift the patient's body when turning over, and avoid pulling and other actions to avoid damage due to friction.

Air cushion beds are commonly used in clinical practice to change the pressure part of the human body and prevent the occurrence of pressure sores.

3.Decompress regularly.

Turn the patient over regularly, such as once every 1-2 hours, to relieve pressure on the pressure area, using special mattresses, wheelchairs, nursing pads, etc.

Explanation of the term pressure ulcer refers to the ulceration and necrosis of soft tissues caused by prolonged compression of local tissues, blood circulation disorders, and local persistent ischemia and hypoxia dystrophy.

Pressure ulcers, also known as pressure injuries, refer to localized injuries to the subcutaneous tissue, often occurring in areas of bone eminence and contact with medical devices or other devices. Pressure ulcers are common in people who are bedridden for a long time, unable to take care of themselves, or in wheelchairs for a long time, unable to stand and walk, and can manifest as local redness, and in severe cases, can form deep holes in muscles or bones.

Pressure ulcers manifest differently depending on the time of local compression, and can be divided into the following four stages:

The first stage, also known as the early stage, is complete, and the redness appears at the bony prominence, and the redness does not go away after 30 minutes of pressure removal. At this stage, you can turn over and decompress the pressure area to prevent the pressure ulcer from developing further deeply.

Stage 2, ** Broken or blistered. At this stage, attention should be paid to decompression, keep the wound clean, protect the wound, and prevent infection.

Stage 3, ** breaks the damage to the fat layer. At this time, attention should be paid to decompression, wound protection, and regular dressing changes.

Stage IV, ulceration, tissue necrosis, or damage, which can reach bone, muscle, or tendon tissue. At this time, it is more difficult, in addition to strengthening the turning over and decompression measures, you need to change the dressing regularly, and you should go to the hospital for treatment.

Pressure sores refers to the ulceration and necrosis of soft tissues caused by long-term compression of local tissues, blood circulation disorders, and local continuous ischemia, hypoxia, and malnutrition. Pressure ulcers are also called pressure sores.

Pathogenesis: Due to the compression of blood vessels, the flow of qi and blood is not smooth, and the wound cannot obtain effective blood and oxygen supply; In turn, the wound cannot be healed, and the festering surface of the wound becomes larger and larger, causing death.

Common incidence groups: middle-aged and elderly people who have been bedridden for a long time.

Pressure ulcer refers to the ulceration and necrosis of soft tissues caused by long-term compression of local tissues, impaired blood circulation, and persistent ischemia and hypoxia dystrophy.

Pressure ulcer, as the name suggests, refers to the wound caused by long-term compression, which is generally due to the patient's weakness and long-term bed rest, resulting in long-term compression of body tissues, resulting in ischemic hypoxic necrosis of the compression position of bone protrusion.

Pressure ulcer refers to the long-term compression of local tissues of the body, blood circulation disorders, and the continuous ischemia, hypoxia, and malnutrition of local tissues, resulting in ulceration and necrosis of soft tissues.

The meaning of pressure ulcers: the body parts are compressed for a long time, which causes blood circulation disorders, persistent blood and hypoxia, and ulcers and necrosis of the internal soft tissues caused by malnutrition.

2. Sores pinyin: chuāng.

radical: 疒; Strokes: 9; Traditional: sores; Wubi: uwbv.

Interpretation: ** or mucosal ulceration disease; Trauma.

3. Pressure ulcer patients mostly occur in patients who are critically ill, elderly, frail, poor in nutritional status, impaired in consciousness, long-term bedridden, bedridden or unable to move automatically in a wheelchair.

According to the pathological changes that occur in bedsores, the clinical course can be divided into three stages:

The first period - the red shift period; The local version of the blood ** is insufficient, the tissue hypoxia right, the arteriolar reactive dilation, the compression site is manifested as local blood stasis, **erythema, but this stage** is not broken.

Stage 2 - blistering stage; Epidermal blisters form or fall off, and the dermis and subcutaneous tissues are swollen, darkened, and induration is obvious.

Stage 3 - ulcerative stage; Confined to**full-thickness necrosis, due to lack of blood at the base of the ulcer**, pale, granule edema, and non-stop water. It should be carried out in time with drugs such as Boxutang muscle ointment to avoid deterioration of the condition.

Pressure ulcers are caused by long-term compression of local state tissues, resulting in local tissue ulceration and avascular necrosis caused by persistent ischemia, hypoxia, and malnutrition. Also known as bedsores, pressure ulcers. It usually occurs in the sacrum, at the site of bony carina, or at the site of contact with medical devices or other devices.

May present as intact** or open ulcers, which may be painful. Intense or long-term pressure or stress combined with shear force can lead to pressure ulcers, and factors such as microenvironment, nutrition, tissue perfusion, and comorbidities can also affect the tolerance of local tissues to pressure and shear forces, thereby increasing the risk of pressure ulcers.

In the hair of pressure ulcers, the pressure and time of compression are directly related to the focus, and the others are related to humidity, temperature, and nutritional status. Pressure ulcers are most commonly found in the hips, heels, hips, elbows, shoulder blades, and occipital regions. Severity is related not only to the size of the pressure ulcer, but also to the depth, presence or absence of necrosis, and infection.

Pressure ulcers, also known as pressure ulcers and bedsores, are caused by long-term pressure on local tissues, resulting in tissue ulceration and necrosis due to continuous ischemia, hypoxia, and malnutrition. Pressure ulcers are a common problem in nursing care. According to the literature, about 60,000 people die each year from pressure ulcer complications.

At the same time, there are different grades according to the specific symptoms and the site of infiltration.

Pressure ulcers usually occur in areas where there is pressure and lack of adipose tissue protection, there is no muscle wrap, or there is a thin muscular bony carina. Avoiding long-term pressure and decompression of the same area is a basic precaution. Bedridden patients should turn over every 2 to 3 hours, alternate left and right decubitus positions or flat grip ulnar decubitus, and use soft pillows, air pillows, water pillows, sponge rings, etc. to pad the bone protrusion, and pay attention to protecting the heels.
