Final answer:
Pressure ulcers are characterized by skin and tissue necrosis due to sustained pressure, usually on bony prominences in immobile patients. They can progress from superficial redness to deep wounds prone to infection, requiring proactive prevention and aggressive treatment.
Step-by-step explanation:
The features associated with pressure ulcers, also known as bedsores or decubitus ulcers, include areas of skin and tissue necrosis due to prolonged pressure, often on bony prominences. This pressure compromises blood flow, leading to tissue injury or death. Bedsores tend to develop in individuals who are immobile for extended periods, such as elderly patients or those with debilitating conditions. Bedsores can present in various stages, from red and unbroken skin to deep craters exposing muscle and bone, potentially becoming infected and leading to serious complications. Preventative measures, such as regular repositioning and pressure-relieving mattresses, are crucial to prevent the development of these wounds.
To manage pressure ulcers, it is important to eliminate pressure points and provide appropriate wound care, such as the removal of necrotic tissue and the application of dressings. If left untreated, infections like cellulitis or more severe conditions like necrotizing fasciitis can occur, with fatal consequences in some cases. The occurrence of pressure ulcers also highlights the need for vigilant care and monitoring in health facilities to prevent the incidence and progression of these wounds.
