Staging and nursing care of pressure sore

Pressure sore stage and nursing points: 1) Congestion and ruddy stage: prevent local continuous compression, increase the number of revolutions, and protect local skin with transparent patch or decompression patch. 2) Inflammation invasion period: covering hydrocolloid dressing (transparent patch, ulcer patch). If there is a blister, cover it with a transparent patch first, and then pump out the liquid in the blister with a sterile syringe to avoid local pressure and promote the repair of epithelial tissue. 3) Ulcer stage: choose various treatment and nursing measures, change dressing regularly, remove necrotic tissue, increase nutrient intake and promote wound healing.
