L89.603

Clinical Causes: Prolonged pressure on the heel, often due to immobility or inability to shift positions regularly Limited sensation or paralysis leading to unawareness of pressure buildup Friction and shear forces that weaken skin integrity over bony prominences Poor nutrition and hydration that compromise skin resilience Inadequate skin care or hygiene practices Medical conditions reducing blood flow, such as diabetes or peripheral vascular disease Use of supportive devices or casts that restrict movement and pressure distribution

Key Symptoms: Open wound on the heel with visible tissue damage Full-thickness skin loss, often exposing subcutaneous tissue Presence of necrotic (dead) tissue deep within the wound Possible drainage or pus indicating infection Swelling, redness, or warmth around the ulcer Pain or tenderness in the affected area Signs of local infection such as foul odor or increased warmth

Diagnosis Path: Diagnosis typically involves a clinical examination of the ulcer, assessing its depth, size, and tissue involvement. Healthcare professionals may use tools like wound photography and measurement to monitor progress. In some cases, additional tests such as tissue cultures or imaging studies may be performed to rule out infection or assess the extent of tissue damage.

Treatment Protocols: Treatment of stage 3 pressure ulcers aims to promote healing, prevent infection, and manage pain. Approaches include: - **Wound care:** Regular cleaning, debridement of necrotic tissue, and appropriate dressing changes - **Offloading:** Reducing pressure on the affected heel through specialized cushions, beds, or devices - **Nutritional support:** Ensuring adequate nutrition and hydration to support tissue repair - **Infection control:** Use of antibiotics if infection is present - **Surgical intervention:** In some cases, procedures like skin grafts or flap surgeries may be necessary to close the wound - **Monitoring:** Regular assessment of wound healing progress and adjustments to care plan Preventive measures are also critical, including frequent repositioning, skin inspections, and maintaining good hygiene to prevent progression and additional ulcers.
