Introduction

Pressure ulcers are an injury that breaks down the skin and underlying tissue. They are caused whenan area of skin is placed under pressure.

They are sometimes known as "bedsores" or "pressure sores".

Pressure ulcers can range in severity from patches of discoloured skin to open wounds that expose the underlying bone or muscle.

They can also occur when less pressure is applied over a longer period of time.

The extra pressure disrupts the flow of blood through the skin. Without a blood supply, the affected skin becomes starved of oxygen and nutrients, and begins to break down, leading to an ulcer forming.

Pressure ulcers tend to affect people with health conditions that make it difficult to move, especiallythose confined to lying ina bed or sitting for prolonged periods of time.

Conditions that affect the flow of blood through the body, such as Type 2 diabetes , can also make a person more vulnerable to pressure ulcers.

Who is affected?

It's estimated that just under half a million people in the UK will develop at least one pressure ulcer in any given year. This is usually people with an underlying health condition for example, around1 in 20 people who are admitted to hospital with a sudden illness will develop a pressure ulcer.

People over 70 years old are particularly vulnerable to pressure ulcers, as they are more likely to have mobility problems and ageing skin.

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. Surgery is sometimes recommended for the most serious cases.

For some people, pressure ulcers are an inconvenience that require minor nursing care. For others, they can be seriousand lead to life-threatening complications, such as blood poisoning or gangrene .

Therefore, a range of techniquesis used to prevent them developing in the first place. These include:

  • regularly changing a person's position
  • using equipment to protect vulnerable parts of the body such as specially designed mattresses and cushions

Unfortunately, even with the highest standards of care, it's not always possible to prevent pressure ulcers in particularly vulnerable people.
