This document discusses bed sore management and prevention. It defines bed sores as injuries to the skin and underlying tissues caused by prolonged unreleived pressure. Risk factors include advanced age, malnutrition, physical disability, and chronic illness. Bed sores are staged from Stage 1 involving changes in skin color to Stage 4 involving full thickness tissue loss reaching muscle, bone and tendon. Treatment involves surgical procedures like debridement, dressings, antibiotics, regular posture changes, diet, and hygiene to prevent further complications. The nursing perspective focuses on assessing risk factors, inspecting the skin and environment, staging any sores present, and ensuring regular care and prevention measures.
