About pressure ulcers Pressure ulcers are an injury that breaks down the skin and underlying tissue.

They are sometimes known as "bedsores" or "pressure sores". How pressure ulcers develop Pressure ulcers can develop when a large amount of pressure is applied to an area of skin over a short period of time. Who is affected?

Treating and preventing pressure ulcers Treatment for pressure ulcers includes the use of dressings, creams and gels designed to speed up the healing process and relieve pressure. These include: regularly changing a person's position using equipment to protect vulnerable parts of the body — such as specially designed mattresses and cushions Read about treating pressure ulcers and preventing pressure ulcers for more information. Symptoms of pressure ulcers The parts of the body most at risk of developing pressure ulcers are those that are not covered by a large amount of body fat and are in direct contact with a supporting surface, such as a bed or a wheelchair.

For example, if you are unable to get out of bed, you are at risk of developing pressure ulcers on your: shoulders or shoulder blades elbows back of your head rims of your ears knees, ankles, heels or toes spine tail bone the small bone at the bottom of your spine If you are a wheelchair user, you are at risk of developing pressure ulcers on: your buttocks the back of your arms and legs the back of your hip bone Severity of pressure ulcers Healthcare professionals use several grading systems to describe the severity of pressure ulcers.

Grade 1 A grade 1 pressure ulcer is the most superficial type of ulcer. Grade 2 In grade 2 pressure ulcers, some of the outer surface of the skin the epidermis or the deeper layer of skin the dermis is damaged, leading to skin loss.

Grade 3 In grade 3 pressure ulcers, skin loss occurs throughout the entire thickness of the skin. Grade 4 A grade 4 pressure ulcer is the most severe type of pressure ulcer. People with grade 4 pressure ulcers have a high risk of developing a life-threatening infection. Causes of pressure ulcers Pressure ulcers are caused by sustained pressure being placed on a particular part of the body.

Pressure ulcers can be caused by: pressure from a hard surface — such as a bed or wheelchair pressure that is placed on the skin through involuntary muscle movements — such as muscle spasms moisture — which can break down the outer layer of the skin epidermis The time it takes for a pressure ulcer to form will depend on: the amount of pressure how vulnerable a person's skin is to damage Grade 3 or 4 pressure ulcers can develop quickly.

Increased risk There are several factors that increase the risk of developing pressure ulcers. These include: with age, the skin loses some of its elasticity stretchiness , which makes it more vulnerable to damage reduced blood flow to the skin, due to the effects of ageing the amount of fat under the skin tends to decrease as people get older Incontinence Both urinary incontinence inability to control your bladder and bowel incontinence inability to control your bowels can cause certain areas of the skin to become moist and vulnerable to infection.

Mental health conditions People with severe mental health conditions such as schizophrenia a condition where people have problems telling the difference between reality and imagination or severe depression have an increased risk of pressure ulcers for a number of reasons.

These include: their diet tends to be poor they often have other physical health conditions, such as diabetes or incontinence they may neglect their personal hygiene, making their skin more vulnerable to injury and infection.

Diagnosing pressure ulcers Pressure ulcers are easily diagnosed by looking at them. As part of the risk assessment process, the following will be considered: your general health your ability to move whether you have any problems that may affect your posture whether you have any symptoms that may indicate an infection your mental health whether you have had pressure ulcers in the past whether you have urinary incontinence or bowel incontinence your diet how well your blood circulation system is working As part of the risk assessment, you may be referred for blood and urine tests.

Self-assessment If you are thought to be at risk of developing pressure ulcers, but you are not staying in a hospital or care home, you may be advised to regularly check for early signs of the condition. Treating pressure ulcers Treatment for pressure ulcers can vary, depending on the grade of the ulcer. Your care team Pressure ulcers are a complex health problem arising from many interrelated factors.

Your MDT may include: a tissue viability nurse a nurse who specialises in wound care and prevention a social worker a physiotherpist an occupational therapist a dietitian medical and surgical experts with experience in pressure ulcer management Changing position It's important to avoid putting pressure on areas that are vulnerable to pressure ulcers or where pressure ulcers have already formed. You may also be given training and advice about: correct sitting and lying positions how you can adjust your sitting and lying position how often you need to move or be moved how best to support your feet how to maintain good posture the special equipment you should use and how to use it Mattresses and cushions There are a range of special mattresses and cushions that can relieve pressure on vulnerable parts of the body.

Dressings Specially designed dressings and bandages can be used to protect pressure ulcers and speed up the healing process. Examples of these types of dressings include: hydrocolloid dressings — these contain a special gel that encourages the growth of new skin cells in the ulcer, while keeping the surrounding healthy area of skin dry alginate dressings — these are made from seaweed and contain sodium and calcium, which are known to speed up the healing process Creams and ointments Topical preparations, such as creams and ointments, can be used to help speed up the healing process and prevent further tissue damage.

Antibiotics If you have a pressure ulcer, you will not routinely be prescribed antibiotics. Nutrition Certain dietary supplements, such as protein, zinc and vitamin C, have been shown to accelerate wound healing. Debridement In some cases, it may be necessary to remove dead tissue from the ulcer to help stimulate the healing process. Some mechanical debridement techniques include: cleansing and pressure irrigation — where dead tissue is removed using high-pressure water jets ultrasound — dead tissue is removed using low-frequency energy waves laser — dead tissue is removed using focused beams of light surgical debridement — dead tissue is removed using surgical instruments, such as scalpels and forceps A local anaesthetic will be used to numb the area of skin and tissue around the ulcer so that debridement does not cause any pain or discomfort.

Maggot therapy Maggot therapy, also known as larvae therapy, is an alternative method of debridement. Surgery It's not always possible for a grade 3 or 4 pressure ulcer to heal. There is a risk of a large number of possible complications occurring after surgery, including: infection tissue death of the implanted flap muscle weakness blisters small pockets of fluid that develop inside the skin recurrence of the pressure ulcers blood poisoning infection of the bone osteomyelitis internal bleeding abscesses painful collections of pus that develop inside the body deep vein thrombosis a blood clot that develops inside the veins of the leg Despite the risks, surgery is often a necessity to prevent life-threatening complications, such as blood poisoning and gangrene the decay or death of living tissue.

Complications of pressure ulcers Even with the best possible medical care, complications can arise from grade 3 or grade 4 pressure ulcers and can occasionally be life-threatening. These complications are discussed below. Cellulitis Infection can spread from the site of the pressure ulcer to a deeper layer of skin. Read more information about cellulitis. Blood poisoning If a person with a weak immune system has a pressure ulcer that becomes infected, there is a risk that the infection will spread into their blood and other organs.

Bone and joint infection Infection can also spread from a pressure ulcer into underlying joints septic arthritis and bones osteomyelitis. Necrotising fasciitis Necrotising fasciitis, commonly known as "flesh-eating" bacteria, is a serious skin infection that causes rapid tissue death. Gas gangrene Gas gangrene is a serious but rare form of infection that occurs when a pressure ulcer becomes infected with the clostridium bacteria. Preventing pressure ulcers As part of your treatment plan, your care team will discuss with you the best way to prevent pressure ulcers.

However, you may find that the general advice outlined below is helpful. Changing position Making regular and frequent changes to your position is one of the most effective ways of preventing pressure ulcers. Nutrition Eating a healthy, balanced diet that contains an adequate amount of protein and a good variety of vitamins and minerals can help prevent skin damage and speed up the healing process. If you currently have a reduced appetite due to a pre-existing health condition, the following advice may be useful: Try eating smaller meals throughout the day, rather than 2 or 3 larger meals.

Research indicates that as many as five percent of individuals admitted to a hospital, nursing home or health care facility can develop a pressure ulcer within a week or two. The most common bedsore occurrences happened by a variety of reasons including:.

Decubitus ulcers often appear in various stages depending on severity. Medical care identifying or grade the sore, based on the depth of the ulcer. The National Institutes of Health NIH recommends consulting a healthcare provider as soon as possible whenever a noticeable bedsore appears. This is because surgery is usually required to repair and heal this kind of wound. The healing process of a decubitus ulcer often involves:.

Abstract Severe pressure ulcers and deep tissue injury are associated with higher mortality rates, longer hospital stays, and costly treatment. Evidence from Clinical Studies Perhaps the most cited paper about the effect of the time on PU onset, the retrospective study by Reswick and Rogers 5 suggested that external pressures exceeding approximately diastolic pressure cause PUs within approximately 6 hours and higher external pressures approximately four times the systolic pressure cause PU in less than 1 hour.

Evidence from Animal Models Results of a meta-analysis of pressure-time combinations causing muscle tissue damage in rats used as models of PU and DTI recently were reported by Linder-Ganz et al. Kosiak M. Etiology of decubitus ulcers. Bedsores are also called pressure injuries, pressure sores, pressure ulcers, or decubitus ulcers. Bedsores can be a serious problem among frail older adults. They can be related to the quality of care the person receives.

If an immobile or bedridden person is not turned, positioned correctly, and given good nutrition and skin care, bedsores can develop. People with diabetes, circulation problems, and poor nutrition are at higher risk. A bedsore develops when blood supply to the skin is cut off for more than 2 to 3 hours. As the skin dies, the bedsore first starts as a red, painful area, which eventually turns purple. Left untreated, the skin can break open and the area can become infected.

A bedsore can become deep. It can extend into the muscle and bone. Once a bedsore develops, it is often very slow to heal. Depending on the severity of the bedsore, the person's physical condition, and the presence of other diseases such as diabetes , bedsores can take days, months, or even years to heal. They may need surgery to help the healing process. Being bedridden, unconscious, unable to sense pain, or immobile increases the risk that a bedsore will develop.

The risk increases if the person is not turned, positioned correctly, or provided with proper nutrition and skin care. People with diabetes, circulation problems and malnutrition are at higher risk.

A wound is not assigned a stage when there is full-thickness tissue loss and the base of the ulcer is covered by slough or eschar is found in the wound bed.
