The treatment of pressure sores focuses on prevention. Once pressure sores occur, the effort and economy spent are very high, so the main focus is on prevention: 1. To reduce and relieve pressure, reducing local pressure is the best measure to prevent pressure sores. Pressure-reducing tools and equipment such as air beds and cushions can be used. Patients who are bedridden for a long time should turn over at least once every 2 hours, and if redness of the skin is found that cannot subside, the turning time should be shortened. Patients with paraplegia due to spinal cord injury should be turned using the axial turning method, with the head and shoulders and waist and legs kept in the same line and turned in the same direction at the same time. The lateral position should be at a certain angle to reduce the local pressure on the hip and external ankle, and soft cushions can also be used to avoid direct pressure on the bony prominence. The two lower legs should be placed in a good position, and such soft cushions can be padded between the two legs. Patients who are bedridden for a long time are most likely to be pressurized at the sciatic tuberosity, and it is recommended to change position once in about 20-30 minutes; 2. To lift the patient out of bed or wheelchair before moving, try to avoid dragging, pulling and tugging leading to skin abrasions; 3. To manage the patient’s urine and stool, avoid impregnation with urine and stool, keep the local skin dry, and change bed sheets regularly; 4. To strengthen nutrition, the incidence of pressure sores in malnourished patients will The incidence of pressure ulcers in malnourished patients is greatly increased, and high protein, high calorie and high vitamin foods can be eaten. Patients with anemia and low protein should correct the anemia and low protein, and diabetic patients should control their blood sugar.
