Understanding Bed Sores (Decubitus Ulcers)
In the medical field, the term "bed sores" refers to pressure ulcers or decubitus ulcers that can develop on areas of the body subjected to prolonged pressure from lying in bed or sitting for long periods. Bed sores are a serious potential complication for immobile or bedridden patients.
Causes of Bed Sores
Bed sores form when constant pressure cuts off blood circulation to an area of skin. Without adequate blood flow, the skin becomes damaged and begins to break down and rot. Common problem areas include:
Back of the Head
Constant pressure against the pillow can cause sores for bedridden patients.
Shoulder Blades
Lying on the back places weight on the protruding shoulder blades.
Elbows
Weight on the elbows when lying on the side can lead to sores.
Tailbone
Sitting puts pressure on the tailbone, especially for wheelchair users.
Hips and Buttocks
The largest areas of weight-bearing when lying supine lead to some of the most common sores.
Heels and Ankles
Even with special boots, pressure on the feet from immobilization can cause sores.
Stages of Progression
Bed sores are classified into four progressive stages based on severity:
Stage 1
Reddened skin that does not blanch or whiten with pressure indicates the early onset of damage.
Stage 2
The skin breaks open, forming a shallow ulcerated wound with pink granulation tissue exposed.
Stage 3
The sore worsens, forming a deeper crater in the skin that exposes subcutaneous fat tissue.
Stage 4
The most advanced stage involves extensive damage extending through the skin into muscle and bone.
Risk Factors
Those at highest risk of developing bed sores include:
- Prolonged immobility or bed confinement
- Advanced age with fragile skin
- Limited sensation due to paralysis or neuropathy
- Conditions affecting blood flow like atherosclerosis
- Poor nutrition status
- Bowel or bladder incontinence
- Debilitating diseases such as cancer or sepsis
Complications
Serious complications can result from severe, chronic bed sores:
Local Infection
Bacteria rapidly colonize open wounds, leading to opportunistic infections like cellulitis.
Osteomyelitis
Infection can spread to the bone underneath deep stage 3-4 sores.
Sepsis
Widespread systemic infection known as sepsis can result from unchecked local infection.
Cancer
Longstanding chronic wounds increase the risk of developing squamous cell carcinoma.
Treatment
Effective treatment focuses on preventing new sores and managing existing ones:
Pressure Relief
Frequently repositioning immobile patients reduces pressure on any one area.
Cushioning
Pillows, foam pads and mattresses redistribute pressure points.
Cleaning
Gently cleaning and debriding wounds prevents infection while promoting healing.
Dressings
Advanced dressings like hydrocolloids maintain a moist environment to stimulate wound healing.
Nutrition
Adequate protein, vitamins and minerals supports tissue regeneration and fights infection.
Prevention
Preventing bed sores involves:
- Frequent repositioning every 1-2 hours
- Regular skin inspection
- Moisturizing dry skin
- Using pressure redistribution devices
- Managing moisture from sweat, urine, etc.
- Optimizing nutrition status
Outlook
Small stage 1 sores often heal within a week or two with proper care. But deeper ulcers may require months to fully close. Severe bed sores may never fully resolve in debilitated patients. With attentive nursing care and early intervention, most bed sores are preventable complications.
While the term “bed sores” may sound alarming, being informed about the causes, staging, and treatment of decubitus ulcers helps patients and caregivers be proactive about prevention and early treatment.
FAQs
What are the most common places for bed sores to develop?
The back/head, hips, tailbone, shoulders, and heels are the most frequent sites affected by bed sores due to pressure when lying or sitting.
How can you prevent bed sores?
Frequently repositioning the patient, using pressure-reducing surfaces, managing moisture, optimizing nutrition, and skin inspections help prevent bed sore formation.
Can bed sores become infected?
Yes, bed sores are prone to developing localized infections or advancing to serious systemic infections like sepsis without proper treatment.
What are the stages of bed sores?
Bed sores range from stage 1 with just reddened intact skin, up to stage 4 with deep wounds extending into muscle and bone.
Who is most at risk for developing bed sores?
Those immobilized or bedridden, elderly patients, individuals with poor circulation or nutrition, and those with bowel incontinence are most prone to bed sores.
