From a medical point of view, if you maintain a prone or sitting position for a long time, local skin such as the part of the buttocks that is in contact with the stool will be subjected to certain pressure. This pressure will affect the blood circulation of the skin tissue of the pressured part, causing ischemia hypoxia. If this state continues, it will easily cause redness, swelling, blisters, and severe ulcers, which can lead to ulcers and necrosis. This skin pathological process, which is mainly caused by pressure, is called bedsore.
Who is prone to bedsores?
It is mainly due to mobility difficulties, such as elderly people who have to stay in bed for a long time due to paralysis or chronic diseases. Patients who have inconvenient mobility after trauma, surgery, or other reasons.
Which part of our body do bedsores occur?
Pressure sores are more likely to occur in areas that are easily compressed or where bones protrude:
When lying on your back, it usually occurs on the back of the head, shoulder blades, buttocks, and heels.
When lying on the side, it usually occurs in the ears, shoulders, hips, the inner and outer sides of the knee joints, and the ankle joints.
When lying prone position, it usually occurs on the cheeks, female breasts, male genitals, knees, etc.
How to prevent it?
1. Turn over body frequently
This is the most basic, simple, and effective measure to prevent bedsores. Especially for long-term bedridden patients who need nursing care to turn over regularly, it is recommended to turn over at least once every two hours. Turning can be performed alternately in the left, right, and flat positions. When turning over, you can use soft pillows, sponge pads, air cushions, and other protection to prevent the patient from falling off the bed. Do not drag, pull, tug, or pull when turning over.
2. Keep the bed and skin clean and dry
Moist irritation such as urine and sweat is the cause of bedsores. Therefore, sweat, urine, and stool stains should be wiped clean in time. Use moisturizers to protect the softness and elasticity of the skin. Keep the bed clean and tidy, and change the sheets in time. Put soft cushions between the protruding parts of bones such as feet and the bottom of the bed.
3. Adequate nutrition
Although malnutrition does not directly cause bedsores, lack of nutrition will thin the subcutaneous fat. Long-term bed rest and weight loss caused by illness will reduce the cushion between the patient’s skin and bones, and increase local skin pressure and the risk of bedsores. Therefore, adequate nutritional intake can prevent bedsores.
4. Avoid wrong care
When cleaning the body of a bedridden patient, it is advisable to wipe the skin with a warm and damp towel and a soft dry towel one by one, gently. However, frequent and excessive skin cleaning should be avoided. It is not recommended to massage locally red skin, because massage may aggravate the damage to the subcutaneous tissue. Do not use harsh disinfectants such as iodine or alcohol to wipe your skin.
