Preventing Pressure Sores: Essential Tips for Wheelchair Users
Pressure sores can be painful and can lead to serious complications, such as infection, sepsis, and even death. Therefore, it is important for wheelchair users to take steps to prevent pressure sores.
Wheelchair users are at an increased risk of developing pressure sores because they are often sitting for long periods of time. The pressure from sitting can cause the skin to break down, especially in areas where there is bony prominence, such as the hips, buttocks, and heels.
Section 1
Understanding Pressure Sores - Causes and Risk Factors
Pressure sores are a significant concern for wheelchair users as they can affect skin health and overall well-being. These sores develop due to sustained pressure on specific areas of the body, leading to reduced blood flow and tissue damage. Understanding the causes and risk factors associated with pressure sores is essential for wheelchair users and caregivers to implement preventive measures effectively. By understanding these causes and risk factors, wheelchair users and caregivers can take proactive measures to prevent pressure sores.
The areas of skin most at risk of pressure sores
Causes of Pressure Sores
Prolonged Pressure: Prolonged periods of sitting or lying in the same position exert continuous pressure on particular body areas, especially bony prominences like the hips, tailbone, heels, and shoulder blades. Over time, this pressure can compromise blood flow, leading to tissue breakdown and pressure sore formation.
Friction and Shear: Friction occurs when the skin rubs against a surface, like the wheelchair seat, while shear refers to the skin’s movement in one direction while the underlying bone moves in the opposite direction – for example, when a bed is elevated at the head, the weight of the body may cause the tailbone to move down in the bed while the skin over the bone may stay in place. These forces can cause skin damage and make the skin more susceptible to pressure sores.
Moisture and Incontinence: Excessive moisture, such as sweat or incontinence, can soften the skin, making it more vulnerable to damage. When the skin is moist, it is more likely to suffer from friction and abrasion, increasing the risk of pressure sores.
Poor Nutrition: Adequate nutrition is crucial for skin health and tissue repair. A diet lacking in essential nutrients, especially proteins, vitamins, and minerals, can impair the body’s ability to withstand pressure and heal effectively.
Risk Factors for Pressure Sores
Immobility: Wheelchair users, who often have limited mobility, are at a higher risk of pressure sores due to the inability to change positions independently. This immobility leads to sustained pressure on certain body areas, increasing the likelihood of pressure sore development.
Sensory Impairment: Individuals with sensory issues, such as those with spinal cord injuries or neurological conditions, may have difficulty sensing discomfort or pain in pressure-prone areas. As a result, they might not be aware of the need to adjust their positions to relieve pressure, leading to an increased risk of pressure sores.
Age: Advanced age can be a contributing factor to pressure sore development. Older adults may have thinner skin and reduced blood circulation, making their skin more susceptible to damage and slower to heal.
Chronic Health Conditions: Certain medical conditions, like diabetes and vascular disease, can compromise blood flow and impede the healing process, increasing the risk of pressure sores.
Poor Circulation: Individuals with circulatory problems face a higher risk of pressure sores due to reduced blood flow. Impaired circulation hinders the body’s ability to deliver nutrients and remove waste products from tissues, leading to tissue breakdown and pressure sore development.
Section 2
Recognising the Stages of Pressure Sores
Pressure sores, in their initial stages, may appear as seemingly harmless red patches on the skin. However, it’s crucial to recognise and understand the different stages of pressure sores to take timely action and prevent further progression. Pressure sores are generally categorised into 6 categories, each with distinct characteristics, symptoms, and potential complications:
Stage 1 pressure sores (also known as ‘Non-Blanchable Pressure Sores’) are characterised by localised areas of skin discoloration, often appearing as red, pink or purple patches on the skin.
The affected skin area may feel warmer or cooler to touch than the surrounding areas. At this stage the skin is still intact and there is no visible open wound.
If identified at this stage, prompt intervention can prevent the sore from advancing and developing into a more severe stage.
Stage 2 pressure sores (also known as ‘Partial Thickness Skin Loss Pressure Sores’) involve, as the name suggests, partial-skin loss. The affected area may appear as an open wound or blister.
The wound will be tender and painful, with redness and swelling potentially present around the damaged skin area.
Without proper care, stage 2 pressure sores can progress and cause further tissue damage.
Stage 3 pressure sores (also known as ‘Full Thickness Skin Loss Pressure Sores’) involve full thickness skin loss. The damaged area extends beyond the outer layer of skin into the underlying tissue, creating a deeper ulcer.
The ulcer may look like a small crater with visible fat tissue, there may also be a foul odour present.
Stage 3 pressure sores are at a high risk of infection and require immediate medical attention to prevent very serious complications.
Stage 4 pressure sores (also known as ‘Full Thickness Tissue Loss Pressure Sores’) are the most severe and involves extensive tissue damage and will have exposed bone, tendons or muscle.
The wound is likely to expose muscle, tendons and even bones an there may be significant amounts of dead tissue present.
Stage 4 pressure sores can lead to severse infections, affection both the skin and deeper tissues. They can also be life threatening and require intensive medical treatment.
In some instances, pressure sores are designated as ‘unstageable’ if the full extent of tissue damage cannot be observed due to the presence of slough (yellow, tan, grey or brown dead tissue) or eschar (hardened blackened tissue) covering the wound.
In these instances, medical professionals need to remove the dead tissue in order to assess and treat the wound appropriately.
Recognising the stages of pressure sores is crucial for prompt intervention and preventing any further deterioration.
