Decubitus Ulcers: A Comprehensive Overview


Decubitus ulcers, also known as pressure ulcers or bedsores, are localized injuries to the skin and underlying tissue that occur due to prolonged pressure on specific areas of the body. They typically develop in areas where bones are close to the skin, such as the tailbone, heels, hips, and shoulders. Decubitus ulcers can range in severity from superficial abrasions to deep wounds that extend into the muscle or bone.

Risk Factors

Immobility: The primary risk factor for developing decubitus ulcers is immobility. Individuals who are confined to bed or spend extended periods seated in a wheelchair or chair are more likely to experience pressure on specific body parts. This constant pressure can restrict blood flow to the affected areas, leading to tissue damage.

Sensory Impairment: People with sensory impairments, such as spinal cord injuries or peripheral neuropathy, may not be able to feel pressure or pain in certain areas of their bodies. This lack of sensation increases the risk of developing decubitus ulcers because individuals may not be aware of the need to reposition themselves or relieve pressure.

Nutritional Deficiencies: Poor nutrition can contribute to the development of decubitus ulcers by weakening the skin and underlying tissues. Malnutrition impairs the body’s ability to repair damaged tissue and fight infection.

Moisture: Excessive moisture from perspiration, incontinence, or wound drainage can soften the skin and make it more susceptible to breakdown. Moisture creates a favorable environment for bacteria growth, increasing the risk of infection.

Other Medical Conditions: Certain medical conditions, such as diabetes, vascular disease, and heart failure, can compromise blood flow to the skin and increase the risk of decubitus ulcers.


Decubitus ulcers develop when prolonged pressure on a localized area of the skin reduces blood flow to the affected tissues. This ischemia leads to cellular damage, inflammation, and tissue death. The skin over the affected area breaks down, exposing the underlying tissues.

The severity of a decubitus ulcer depends on the duration and intensity of pressure, as well as the underlying health status of the individual. Ulcers can be classified into four stages:

Stage 1: Intact skin with redness and tenderness Stage 2: Partial-thickness skin loss with exposed dermis Stage 3: Full-thickness skin loss with exposed subcutaneous tissue Stage 4: Full-thickness skin loss with exposed muscle, bone, or tendon

Clinical Presentation

Early Signs:

  • Redness and warmth of the affected area
  • Tenderness to the touch
  • Pain or discomfort

Advanced Signs:

  • Open wound with varying degrees of skin loss
  • Yellow or black eschar (dead tissue)
  • Foul odor
  • Drainage


The management of decubitus ulcers involves a multidisciplinary approach that includes:

Pressure Relief:

  • Repositioning the patient every 2-4 hours
  • Using pressure-relieving surfaces, such as air mattresses or foam cushions
  • Offloading pressure from affected areas

Wound Care:

  • Cleaning and dressing the wound regularly
  • Debridement to remove dead tissue
  • Antibiotics if infection is present

Nutritional Support:

  • Ensuring adequate protein and calorie intake
  • Providing supplements if necessary

Moisture Management:

  • Keeping the wound area clean and dry
  • Using moisture-absorbing dressings

Other Therapies:

  • Electrical stimulation
  • Hyperbaric oxygen therapy
  • Negative pressure wound therapy


Preventing decubitus ulcers is crucial for individuals at risk. Preventive measures include:

  • Regular repositioning
  • Skin assessment
  • Pressure redistribution devices
  • Adequate nutrition
  • Moisture management
  • Patient education


Decubitus ulcers can lead to a variety of complications, including:

  • Infection: Open wounds are highly susceptible to bacterial infection.
  • Osteomyelitis: Infection of the bone can occur if the decubitus ulcer extends to the underlying bone.
  • Sepsis: Severe infection that spreads to the bloodstream.
  • Contractures: Stiffness and deformity of joints caused by prolonged pressure on tendons and muscles.
  • Amputation: In severe cases, amputation may be necessary if the ulcer becomes infected or does not respond to treatment.


The prognosis for decubitus ulcers depends on the severity of the ulcer, the underlying health status of the individual, and the timeliness of treatment. Early detection and intervention are crucial to prevent complications and improve outcomes.


Decubitus ulcers are a serious health problem that can significantly affect an individual’s quality of life. By understanding the risk factors, pathophysiology, and management strategies, healthcare professionals and caregivers can effectively prevent, treat, and manage these wounds. Early detection, pressure relief, and comprehensive wound care are essential for achieving optimal outcomes and minimizing the risk of complications.
