decubitus ulcer

A decubitus ulcer, also known as a pressure ulcer or bedsore, is an open wound on the skin caused by prolonged pressure to a specific area of the body. This pressure can cut off blood flow to the skin and underlying tissues, leading to damage and eventually an open sore.

Decubitus ulcers can form anywhere on the body where there is constant pressure, such as:

• The bridges of the nose, ears, or back of the head in people who use oxygen therapy
• Inside the mouth from ill-fitting dentures, intubations, or mechanical ventilation
• Over bony prominences, such as the sacrum, ischial tuberosity, and greater trochanter

The skin in the affected area can die and leave an open sore (ulcer) due to decreased blood flow and resulting damage. Decubitus ulcers are often painful and can be categorized into four stages of severity.

Causes and Risk Factors:

• Prolonged pressure on a specific area of the body
• Decreased blood flow to the skin and underlying tissues
• Pre-existing health conditions or injuries that affect mobility or sensation

Symptoms:

• Redness or discoloration of the skin in the affected area
• Warmth or swelling of the affected area
• Open sore (ulcer) formation if pressure is not relieved

Decubitus ulcers are a serious medical condition that requires prompt attention and treatment to prevent further complications.

Decubitus Ulcer Signs and Symptoms

A decubitus ulcer, also known as a pressure sore or bedsore, is a type of skin injury that occurs when prolonged pressure on the skin causes damage to the underlying tissue. The signs and symptoms of a decubitus ulcer can vary depending on the stage and severity of the condition.

Common Signs and Symptoms:

• Changes in skin color or texture: The affected area may become red, purple, blue, or black due to poor blood flow.
• Swelling: The skin around the affected area may become swollen and inflamed.
• Pus-like draining: In severe cases, a decubitus ulcer can become infected, leading to pus-like drainage from the wound.
• An area of skin that feels cooler or warmer to the touch than other areas: This is often an indication of poor blood flow to the affected area.

Additional Signs and Symptoms:

• Extremely painful: Decubitus ulcers can be extremely painful, especially if they become infected.
• Foul smelling: Infected decubitus ulcers can have a foul or unpleasant odor.
• Red and very warm to the touch: The affected area may feel red and warm to the touch due to inflammation.
• Swollen: The skin around the affected area may become swollen and inflamed.

Early Warning Signs:

• Discolored patches of skin that do not change color when pressed: This can be an early sign of a decubitus ulcer, especially if the patches are red on white skin or purple on darker skin.
• Red, blue, or purplish patches on the body: These patches may not turn white when touched and can be an indication of poor blood flow.

Diagnostic Tests for Decubitus Ulcer

Decubitus ulcers, also known as pressure sores or bedsores, can be diagnosed through a combination of physical examination and various diagnostic tests.

• Physical Examination: Doctors can usually diagnose pressure sores by doing a physical examination and noting the appearance and location of the sores [6].
• Imaging Tests: A positive bone scan finding can be evaluated further by means of magnetic resonance imaging (MRI) or bone biopsy [2]. Additionally, deep tissue biopsy, MRI, wound swab, ESR, WBC, serum glucose, and erythrocyte sedimentation rate are also considered for testing [5].
• Biopsy: Your healthcare professional may take a biopsy, or sample of the fluids and tissue in your decubitus ulcer, and send it to a lab for testing [8]. This can help determine the extent of the wound and the bacteria involved.
• Blood Tests: Blood tests such as erythrocyte sedimentation rate (ESR) and white blood cell count (WBC) may be ordered to assess your general health and rule out any underlying conditions that may be contributing to the development of pressure sores [1, 4].

It's worth noting that staging helps determine what treatment is best for you, and might require blood tests to learn about your general health [1].

Treatment Options for Decubitus Ulcer

Decubitus ulcers, also known as pressure sores or bedsores, can be treated with a combination of nonsurgical and surgical interventions. While there are no specific "drugs" that can cure decubitus ulcers, certain medications may be used to manage symptoms, prevent infection, and promote healing.

Medications Used in Decubitus Ulcer Treatment

• Systemic antibiotics: These medications may be administered to treat or prevent infections associated with decubitus ulcers. [3]
• Topical dressings: Certain topical dressings, such as alginate, hydrocolloid, and protease-modulating dressings, can help promote healing and protect the wound from infection. [4]

Other Treatment Options

In addition to medications, other treatment options for decubitus ulcers include:

• Wound debridement: Removing dead tissue and debris from the wound to promote healing.
• Pain management: Controlling pain associated with decubitus ulcers using medications or other interventions.

It's essential to note that the type of treatment used will depend on the severity and location of the pressure ulcer. [6]

Decubitus Ulcer Differential Diagnosis

A decubitus ulcer, also known as a pressure sore or bed sore, can be challenging to diagnose accurately. The differential diagnosis for decubitus ulcers includes several conditions that may present with similar symptoms.

• Superficial friction injuries or excoriations: These are minor skin irritations caused by friction or rubbing against the skin.
• Thermal burns: Burns caused by heat or flames can be mistaken for pressure sores.
• Cellulitis: A bacterial infection of the skin and underlying tissues that can cause redness, swelling, and pain.
• Marjolin ulcer: A type of skin cancer that can develop in areas of chronic irritation or trauma.
• Martorell ulcer: A rare condition characterized by a painful, bleeding ulcer on the lower leg.

Key Features to Distinguish Decubitus Ulcers from Other Conditions

To accurately diagnose decubitus ulcers, healthcare professionals should look for the following features:

• Location and distribution: Decubitus ulcers typically occur over bony prominences, such as the sacrum, heels, or hips.
• Appearance: The ulcer may be red, purple, or black, with a surrounding area of inflammation.
• History: A history of prolonged pressure on the affected skin is often present.
