The prevention of decubitus ulcers is based on the “five diligent” tips, namely, turning, scrubbing, tidying, checking and changing. Turning regularly means helping the patient turn over and change the lying position, once every 1-2 hours during the day and up to 3 hours at night to avoid long-term local skin pressure. Scrub regularly, scrub the patient’s body regularly, especially for patients with urinary and fecal incontinence, and keep the skin clean and dry in a timely manner to avoid skin irritation by dirt and filth. The bed should be kept flat and moderately hard and soft, and the bony protrusions can be padded with soft pillows or clothes to reduce the pressure on the bony protrusions and prevent frictional breakage. If erythema or superficial ulceration occurs, it is considered a mild decubitus ulcer, and it is necessary to correct the omission of care in a timely manner. Change the patient’s clothes and bed sheets regularly, especially in hot summer weather, to prevent sweat from infiltrating the skin, and to protect and treat the bony prominence or erythema in a timely manner. Clinical observation shows that many patients do not pay attention to prevention during recuperation and do not pay attention to and deal with pressure areas after mild symptoms appear, giving the opportunity for bed sores to worsen and intensify.
