About- Bedsores, also called pressure ulcers or decubitus ulcers, are injuries to the skin and underlying tissues caused by prolonged pressure, friction, or shear. They most commonly develop in people who have difficulty changing their position, such as those who are bedridden, use a wheelchair, or have limited mobility. Pressure ulcers usually develop over areas where bones are close to the skin and there is less cushioning from muscle and fat. They can range from a small area of discolored skin to a deep wound involving muscle, tendons, or bone. Bedsores can develop and worsen quickly, particularly in people with poor circulation, diabetes, malnutrition, or reduced sensation. Early recognition and appropriate treatment are important to prevent infection and more serious complications.
Healthcare professionals commonly classify pressure ulcers according to the depth and extent of tissue damage.
Stage 1 Pressure Injury- The skin is still intact, but there is a persistent area of discoloration that does not return to its normal appearance when pressure is relieved. The affected area may feel warmer, cooler, firmer, softer, or more tender than the surrounding skin.
Stage 2 Pressure Ulcer- There is partial-thickness loss of skin. The wound may appear as a shallow open ulcer or a blister, and the wound bed is usually exposed.
Stage 3 Pressure Ulcer- There is full-thickness loss of skin, with damage extending into the tissue beneath the skin. Fat may be visible, and the wound may have a crater-like appearance. Muscle, tendon, cartilage, and bone are not exposed at this stage.
Stage 4 Pressure Ulcer- This is a severe pressure injury involving extensive tissue damage. The wound may extend into muscle, tendon, cartilage, or bone and can lead to serious complications.
Unstageable Pressure Ulcer- Sometimes the full depth of a wound cannot be determined because it is covered by dead tissue, such as slough or eschar. In such cases, the ulcer is described as unstageable until the wound can be adequately assessed.
Bedsores develop when prolonged pressure reduces blood flow to an area of the skin and underlying tissue. If pressure continues for a long time, the affected tissue may become damaged or die. Several factors can increase the risk of developing pressure ulcers.
Prolonged pressure from staying in the same position for a long period
Friction caused by being moved or dragged across a bed or chair
Shear, which can occur when the skin remains in place while the underlying body moves
Lack of mobility, including being bedridden or using a wheelchair
Moisture from sweat, urine, stool, or wet bedding
Poor nutrition or malnutrition, particularly inadequate protein intake
Dehydration
Reduced sensation, which may prevent a person from noticing pain or discomfort
Certain medicines and treatments may also contribute indirectly to pressure-ulcer risk by affecting mobility, nutrition, alertness, or the body’s ability to heal.
Without appropriate treatment, a pressure ulcer can become deeper and more difficult to heal. Possible complications include:
Cellulitis, an infection of the surrounding skin and soft tissue
Wound infection
Bone infection (osteomyelitis)
Abscess formation
Damage to muscles, tendons, and other deeper tissues
Sepsis, a potentially life-threatening response to infection
Delayed wound healing
Recurrence of the pressure ulcer
A pressure ulcer that becomes increasingly painful, swollen, warm, red, or produces pus or a foul odor should be assessed by a healthcare professional promptly.
A healthcare professional usually diagnoses a pressure ulcer by examining the affected skin and assessing the depth and extent of tissue damage. During the evaluation, the healthcare professional may assess:
Location and size of the wound
Depth of tissue damage
Skin color and condition
Presence of dead tissue
Drainage or signs of infection
Pain and tenderness
Mobility and ability to change position
Nutritional status
Circulation and sensation
Other medical conditions that may affect healing
Additional tests may be recommended if an infection or deeper tissue involvement is suspected.
Treatment depends on the stage of the pressure ulcer, its location, the person’s general health, and whether an infection is present.
Relieve pressure- The most important step is to remove or reduce pressure from the affected area. This may involve regularly changing the person’s position and using specialized cushions, mattresses, or pressure-relieving devices.
Wound cleaning and dressing- The wound may need to be cleaned and covered with an appropriate dressing. The type of dressing depends on the size, depth, amount of drainage, and condition of the wound.
Removal of dead tissue- If dead tissue is present, a healthcare professional may recommend a procedure called debridement to remove unhealthy tissue and promote healing.
Treatment of infection- If a pressure ulcer becomes infected, appropriate treatment may be required. Antibiotics may be prescribed when there is a clinically diagnosed bacterial infection or another specific indication.
Improve nutrition and hydration- Adequate calories, protein, vitamins, minerals, and fluids are important for tissue repair. A doctor or dietitian may recommend nutritional assessment and supplementation when needed.
Pain management- Pain medicines or other measures may be recommended to control discomfort associated with the wound or its treatment.
Advanced treatment- Severe or non-healing pressure ulcers may require specialized wound care. In selected cases, surgical treatment or reconstructive procedures may be considered.
Consult a healthcare professional if you notice a persistent area of skin discoloration, blister, open wound, or other changes over a pressure point, particularly in a person with limited mobility. Seek prompt medical attention if the wound:
Becomes increasingly painful
Develops spreading redness or swelling
Produces pus or foul-smelling drainage
Becomes warmer than the surrounding skin
Gets deeper or larger
Is associated with fever or chills
Exposes deeper tissue such as muscle or bone
People with diabetes, poor circulation, reduced sensation, or significant mobility problems should be particularly careful about any new skin injury.
Depending on the severity and underlying cause, treatment may also involve a wound-care specialist, surgeon, physician, nurse, dietitian, or other healthcare professional.
1. What are bedsores?
Bedsores, also called pressure ulcers or pressure injuries, are areas of damaged skin and underlying tissue caused mainly by prolonged pressure. They commonly occur over bony areas such as the tailbone, hips, heels, elbows, and back of the head.
2. What causes bedsores?
Bedsores usually develop when prolonged pressure reduces blood flow to the skin and underlying tissues. Friction, shearing, moisture, poor nutrition, dehydration, limited mobility, and poor circulation can increase the risk.
3. Who is most likely to develop bedsores?
People who are bedridden, use a wheelchair, have limited mobility, have reduced sensation, or are unable to change position independently are at increased risk. Older adults and people with diabetes, poor circulation, malnutrition, or incontinence may also be more vulnerable.
4. Where do bedsores usually occur?
They commonly occur over areas where bones are close to the skin. Common locations include the tailbone, buttocks, hips, heels, ankles, elbows, shoulder blades, and back of the head.
5. What are the early signs of a bedsore?
Early signs may include persistent skin discoloration, unusual warmth or coolness, swelling, tenderness, pain, itching, or a change in the firmness or texture of the skin. Early pressure injuries may occur before an open wound develops.
6. Are bedsores painful?
They can be painful, tender, itchy, or burning. However, people with reduced sensation or certain neurological conditions may have little or no pain even when significant tissue damage is present.
7. What are the stages of bedsores?
Pressure ulcers are commonly classified into four stages. Stage 1 involves intact skin with persistent discoloration or other changes. Stage 2 involves partial-thickness skin loss. Stage 3 involves full-thickness skin loss with deeper tissue damage. Stage 4 is the most severe stage and can involve muscle, tendon, cartilage, or bone. Some wounds may initially be classified as unstageable when their full depth is covered by dead tissue.
8. Can bedsores heal?
Yes. Many pressure ulcers can heal with appropriate treatment, but healing time depends on the severity of the wound, the person’s overall health, nutrition, circulation, and ability to relieve pressure from the affected area.
9. How are bedsores treated?
Treatment may include relieving pressure, changing the person’s position regularly, cleaning and dressing the wound, removing dead tissue when necessary, managing pain, improving nutrition and hydration, and treating infection when present. Severe wounds may require specialized wound care or surgery.
10. Can I treat a bedsore at home?
Very early skin changes may improve when pressure is promptly relieved and the skin is protected. However, an open, deep, worsening, infected, or persistent pressure ulcer should be assessed by a healthcare professional. Avoid applying medicines, antiseptics, or home remedies to an open wound without appropriate medical advice.
11. How can bedsores be prevented?
Regularly changing position, inspecting the skin, keeping the skin clean and dry, using pressure-relieving mattresses or cushions when appropriate, maintaining adequate nutrition and hydration, and avoiding friction and shearing can help prevent pressure ulcers.
12. How often should a bedridden person be repositioned?
There is no single repositioning schedule that is appropriate for everyone. The frequency should be individualized according to the person’s health, mobility, skin condition, support surface, and healthcare professional’s recommendations. The skin should be checked regularly for signs of pressure injury.
13. Can a bedsore become infected?
Yes. A pressure ulcer can become infected, particularly when the wound is deep or remains open. Increasing redness, warmth, swelling, pain, pus, foul-smelling drainage, fever, or chills may indicate infection and should receive prompt medical attention.
14. Can bedsores cause serious complications?
Yes. Severe or untreated pressure ulcers can lead to cellulitis, abscesses, bone infection, extensive tissue damage, and potentially life-threatening infections such as sepsis.
15. Do people with diabetes have a higher risk of bedsores?
Diabetes can increase the risk because it may be associated with reduced sensation, impaired circulation, and slower wound healing. People with diabetes should carefully monitor their skin and seek medical advice for wounds that do not heal normally.
16. Can bedsores develop quickly?
Yes. Pressure injuries can develop over a relatively short period, particularly in people who are immobile or have poor circulation and reduced sensation. Regular repositioning and skin inspection are important for people at high risk.
17. Should a bedsore be covered with a dressing?
Many pressure ulcers require an appropriate wound dressing, but the correct dressing depends on the wound’s depth, drainage, location, and condition. A healthcare professional can recommend the most suitable dressing.
18. When should I see a doctor for a bedsore?
Seek medical advice for any persistent pressure-related skin change or open wound. Prompt medical attention is particularly important if the wound is getting larger or deeper, produces pus or a foul smell, develops increasing redness or swelling, or is associated with fever, chills, or severe pain.
19. Which doctor treats bedsores?
A dermatologist may evaluate and treat pressure-related skin problems. Depending on the severity, treatment may also involve a wound-care specialist, surgeon, physician, nurse, or dietitian.
20. Can bedsores be prevented from coming back?
Yes. Preventive measures such as regular repositioning, appropriate pressure-relieving equipment, good skin care, adequate nutrition and hydration, moisture management, and regular skin inspection can reduce the risk of recurrence.
