Implement a strict turning schedule every 2 hours and use pressure-relieving devices (e.g., high-specification foam mattresses). This mechanically offloads the sacrum, restoring capillary blood flow and preventing further necrosis.
Do not massage the area around a pressure injury, as this can damage fragile ischemic capillaries. Avoid using cytotoxic agents like hydrogen peroxide for wound cleansing, as they destroy granulation tissue.
