Long-term bed-ridden vegetative patients are prone to bedsores, and wounds are not easy to heal when combined with diabetes. First of all, if a patient is lying in bed for a long period of time, if he/she does not turn over diligently to promote blood circulation, it will easily lead to long-term pressure on a certain part of the body, resulting in ischemia and necrosis of the skin and the formation of bedsores. Secondly, patients with diabetes mellitus have decreased immunity and poor peripheral microcirculation, which affects blood flow. These factors are not conducive to wound healing. Diabetic patients with high blood sugar state is a good culture medium for microorganisms, the body produces wounds, easy to cause infection, and more unfavorable to wound healing. For long-term bed-ridden people, they need to turn over regularly, keep the local clean, dry and hygienic, avoid extrusion, and at the same time strengthen the care of the patient to improve the nutritional status and promote wound healing.
