Decubitus ulcers
Decubitus Ulcers
Decubitus ulcers, also known as pressure ulcers, bedsores, or pressure sores, are localized injuries to the skin and/or underlying tissue that usually occur over a bony prominence as a result of pressure, or pressure in combination with shear and/or friction.
Pronunciation
Decubitus ulcers: /dɪˈkjuːbɪtəs ˈʌlsəz/
Etymology
The term "decubitus" originates from the Latin word "decumbere", which means "to lie down". The term "ulcer" comes from the Latin word "ulcus", which means "sore".

Causes
Decubitus ulcers often occur when a person is bedridden or otherwise immobilized, unable to change position frequently. This puts pressure on certain parts of the body, particularly bony prominences like the hips, heels, and tailbone. The pressure can reduce blood flow to the area, causing the skin and underlying tissue to break down, forming an ulcer.
Symptoms
Symptoms of decubitus ulcers include red or purple skin that does not lighten when pressed, swelling, and skin that feels warmer or cooler to the touch than the surrounding skin. In severe cases, the ulcers can become deep, extending into the muscle and bone.
Treatment
Treatment for decubitus ulcers includes reducing pressure on the affected area, cleaning and dressing the wound, and in some cases, surgery. It's also important to manage any underlying conditions that could contribute to the development of ulcers, such as diabetes or poor circulation.
Prevention
Prevention strategies for decubitus ulcers include frequent repositioning, using special mattresses or cushions to reduce pressure, and maintaining good nutrition and hydration to keep skin healthy.
