WHAT IS BEDSORE?

Bedsore is an ulcer and necrosis condition that occurs as a result of complete closure of capillaries in the skin and subcutaneous tissues due to long-term or repetitive pressures on bone protrusions and cessation of circulation in that area.

It is also called a pressure sore because it occurs when a region is exposed to prolonged or uninterrupted pressure. However, it is more commonly known as bedsore. Its name in medicine is; decubitus ulcer. The basis of the definition of pressure ulcer is the expression of "impairment of blood circulation in soft tissues exposed to pressure". Pressure is the most important factor that plays a role in the development of bedsores.

Bedsores occur frequently, especially in intensive care units / long-term care beds. Bedsores are seen as an important risk factor for health institutions all over the world, threatening the health of the patient.

Bedsores;

Reduces the patient's quality of life,
Prolongs hospital stay,
Delays patient's recovery,
Increases the risk of complications,
Increase the death rate up to two to three times.

CAUSES OF BEDSORE

Lack of Movement& Immobility,
Constant Pressure in the Same Region,
Failure to Change the Position of the Patient on Time,
Friction, Urine and Moisture,
Inappropriate Bed Surface,
Wrong Sleeping Position,
Patient Tolerence, Not Drinking Enough Water, Malnutrition and Advanced Age.

LOW EMISSIONS AND EFFICIENCY

WHY BEDSORES NOT OCCUR IN HEALTHY PEOPLE?

Healthy people have no sensory perception problems and feel the discomfort caused by tissue hypoxia when the capillaries are closed and change their position, in short, they shift the pressure to other points. We also know this situation as a tingling sensation in the related area. Less than 20 movements during the night significantly increases the risk of bedsore development.

Mediself smart bedsore prevention support surface ensures that the pressure points of those, with perception problems or cannot move, change & the capillaries remain open.

HOW DOES BEDSORES BEGIN?

If, for some reason, the patient does not perceive the capillaries in the parts of his body under pressure, even though they are closed, or cannot move that part of the body, the blood circulation in the capillaries in that area will stop and bedsores will start to develop by first causing cell and then tissue damage. There will be moisture, friction and tears in the skin, first at the micro level and then at the macro level, and the wound site infection will develop with the infectious agents and bedsores will form. If it is not prevented or treated, the wound progresses and follows the stages as seen on the rigth. The treatment for each stage is different and as the wound progresses, the treatment becomes more difficult and the success rate decreases.

EFFECT OF PRESSURE ON WOUND FORMATION

Pressure is the most important factor that plays a role in the bedsore development. Pressure intensity, duration, tissue tolerance and other individual - environmental factors (such as humidity and friction) are important factors affecting the rate of bedsore formation. Time is the most important factor that determines the damaging effect of pressure. There is an inverse relationship between the duration and the intensity of the pressure. While low-intensity pressure can cause tissue damage over a longer time, this is shorter time for high-intensity pressure. Most bedsores develop within 24-48 hours. Personalized treatment plans of risky patients should be realized within 24 hours. Continuous application of 70 mmHg for 2-6 hours causes irreversible tissue damage. However, in hospitalized patients, the duration of the pressure is more risky than the intensity of the compression. Long-term low-intensity pressure plays a greater role in bedsore formation. In addition, lying position, patient's weight, and regional effect differences of pressure are effective in wound formation. In particular, regional pressure control positively affects wound formation. The Mediself Support Surface is unique in this regard.
