Pressure ulcers

Pressure ulcers are chronic wounds that develop on the background of ischemia as a result of compression, friction and shear forces. They occur in typical locations where bone protrusions are near the skin layers and increase compression pressure (mainly in the area of sacrum, coccyx, buttocks, on heels or hips, in severe conditions even on shoulders, ankles, knees).4

Incidence of pressure ulcers

Pressure ulcers may develop in patients who are confined to bed, regardless of patient age.

They cause pain, reduce the patient’s comfort and increase the risk of infections.

There are various approaches to treatment of pressure ulcers such as nutritional support, wound dressings, electrical stimulation, light therapy, ultrasound therapy or the use of local growth factors.5

Pressure ulcers may develop in patients treated in various hospital departments, regardless of patients’ age. They cause additional pain and may be a source of infection. Moreover, they significantly reduce the quality of life of patients requiring long-term confinement to bed.

In addition, the risk of developing pressure ulcers is higher in malnourished patients or patients with low fat free mass.
