Feline Decubitus Ulcer Study Guide
Overview and Clinical Importance
Decubitus ulcers (also known as pressure ulcers, pressure sores, or bed sores) are localized injuries to the skin and underlying tissue resulting from prolonged pressure, typically over bony prominences. In feline patients, these lesions are most commonly encountered in recumbent, paralyzed, or critically ill cats unable to reposition themselves. Understanding the pathophysiology, staging, prevention, and treatment is essential for the NAVLE.
While decubitus ulcers are more commonly tested in canine contexts due to higher incidence in large breed dogs, feline patients present unique challenges due to their smaller size, thinner skin, and tendency to hide illness. Cats recovering from spinal trauma, orthopedic surgery, or systemic diseases are particularly at risk.
