How to prevent pressure sores

Most pressure sores are preventable. It is much better to prevent pressure sores than to treat them. Here are 5 tips to prevent pressure sores.

Change position frequently

One of the best ways to prevent pressure sores is to reduce or relieve direct pressure on the areas at risk by moving around and changing position as much as possible. People who spend most of their time in bed are advised to change position every 2–3 hours, even during the night. People who use a wheelchair are advised to shift position within their chair about every 15 minutes, by leaning forward or moving side to side. If you can't move, ask your carer to reposition you regularly.

Don't drag your heels or elbows when moving 

Don't drag your heels or elbows when moving in your bed or chair. Chafing or friction caused by your skin rubbing against the sheets or other surfaces can remove top layers of skin and cause pain. Instead its best to lift your limbs up. If you are unable to do this, ask your carer for help.

Use pillows, cushions or special mattresses

Using pillows or cushions as soft buffers between your skin and the bed or chair can be helpful. No two skin surfaces should rest against each other, eg, while lying in bed, place a pillow between your knees and ankles to prevent them from touching each other. If you are confined to bed, ask your healthcare provider about the use of heel and knee protectors or pressure relieving mattresses. 

Take care of your skin

Taking care of your skin and doing regular skin checks are important in preventing pressure sores. Check your skin at least once a day for redness, changes in colour, blisters, bruises, cracked, scraped or dry skin. Closely inspect areas that are at especially high risk for pressure sores. The highest risk is where your bones are close to the surface and your skin is directly over bone. Use a mirror to inspect skin in hard-to-see areas or ask your caregiver to help you. If you notice a discolored area, stay off the area until it returns to normal skin colour.

Keep your skin at the right moisture level, as damage is more likely to occur if your skin is either too dry or too moist. Use moisturising products to keep your skin supple and prevent dryness, but avoid massaging bony areas where the skin is too delicate. Immediately wash and dry skin and change clothing after any leakage of stool (poo) or urine (pee). Avoid harsh soaps, skin agents with alcohol and antibacterial or antimicrobial soaps.  

Eat healthily and drink plenty of fluids

Eating a healthy and nutritious diet and preventing dehydration by drinking enough liquid is important in preventing pressure sores. Being obese or having severe weight loss can increase the risk of getting pressure sores. A poor diet can affect the health of your skin and your immune system. Likewise, hydration plays a vital role in your skin's health and helps to repair injured skin. Adequate fluid intake is necessary for wound healing, to support the blood flow to wounded areas and to prevent breakdown of your skin.
