Pressure Ulcers

CLINICAL DIAGNOSTIC MANUAL

Pressure ulcers, also known as bedsores or decubitus ulcers, are injuries to the skin and underlying tissues caused by prolonged pressure on the skin. These ulcers typically develop over bony areas of the body, such as the heels, ankles, hips, and sacrum, and are common in patients with reduced mobility or those confined to a bed or wheelchair for extended periods.Constant pressure decreases blood flow to the skin and underlying tissues, leading to necrosis and ulceration.

Pathology	Symptoms and Clinical Signs	Suspected Diagnosis	Confirmatory Diagnosis
Prolonged contact with surfaces	Erythema, pain, and discomfort in areas over bony prominences. Ulcers classified in stages 1 to 4.	History of immobility or prolonged confinement. Physical examination.	Confirmation with detailed physical examination and assessment of patient mobility.
Malnutrition	Weight loss, weakness, delayed wound healing. Presence of pressure ulcers in various stages.	Medical history of inadequate diet or conditions affecting nutrient absorption. Physical examination.	Confirmation with blood tests showing nutritional deficiencies (proteins, albumin, prealbumin).
