Final answer:
Pressure ulcers, or bedsores, are injuries to skin due to prolonged pressure, most common in immobile, elderly patients. Prevention includes regular repositioning and skin care. Untreated bedsores can lead to serious infections and require removal of dead tissue.
Step-by-step explanation:
Understanding Pressure Ulcers
Pressure ulcers, also known as bedsores or decubitus ulcers, are injuries to skin and underlying tissue resulting from prolonged pressure on the skin. They typically develop on skin that covers bony areas of the body, such as the heels, ankles, hips, and tailbone. People most at risk of bedsores have medical conditions that limit their ability to change positions or cause them to spend most of their time in a bed or chair.
Bedsores can develop quickly and are often difficult to treat. Several strategies can help prevent some bedsores and promote healing. Among these, regularly repositioning to alleviate pressure on sensitive areas, maintaining proper nutrition and hydration, and keeping skin clean and dry are paramount. Especially in hospitals and long-term care facilities, staff are instructed to turn immobile patients every few hours to prevent the onset of pressure ulcers.
If pressure ulcers are left untreated, the affected skin can die, leading to an open wound that is susceptible to infection. The removal of necrotized tissue is necessary to prevent potentially fatal complications. Thus, constant vigilance and proper care are crucial for patients who are at risk.
