Pressure Ulcers and/or Bed Sores

Ailment Overview

Pressure ulcers, commonly known as bed sores, occur when prolonged pressure on the skin impairs blood flow, leading to tissue damage. They are frequent in immobile patients, such as those bedridden or using a wheelchair, and often develop on bony areas like the heels, hips, and back.

Causes:

• Immobility: Individuals who are bedridden, use a wheelchair, or are unable to change positions frequently are at high risk. This immobility leads to continuous pressure on certain parts of the body, especially bony areas.
• Friction and Shear: Friction occurs when the skin rubs against clothing or bedding, and shear occurs when the skin moves in one direction and the underlying bone moves in another. Both can contribute to skin breakdown, particularly in patients with sensitive skin.
• Poor Nutrition and Hydration: Inadequate nutrition and dehydration can weaken the skin and other tissues, making them more susceptible to damage.
• Medical Conditions: Conditions that affect blood flow, such as diabetes and vascular disease, or that reduce sensation in the limbs, can increase the risk of developing pressure ulcers.

Symptoms:

• Skin Discoloration: The skin may develop noticeable patches of red, purple, or blue. These patches are distinct because they remain unchanged and do not fade when pressure is applied to them, indicating a potential disruption in underlying circulation.
• Skin Texture: The texture of the skin affected by the ulcer may undergo noticeable changes; it may feel unusually warm compared to surrounding areas, or it may become firm or spongy when touched. These textural changes suggest alterations in skin integrity and underlying tissues.
• Discomfort: Individuals with pressure ulcers often experience varying degrees of discomfort, including pain or persistent itchiness at the site of the ulcer. This discomfort is a key indicator of the presence and progression of a pressure ulcer.
• Swelling: Swelling is a common symptom surrounding the ulcerated area. The swollen, raised tissue can indicate inflammation and fluid accumulation, which are responses of the body trying to fight the damage.
• Drainage: The presence of fluid or pus draining from the ulcer may signify a potential infection. This drainage can vary in color and consistency, and managing it is crucial for preventing further complications.
• Systemic Symptoms: Systemic signs such as fever or chills may develop if the ulcer becomes infected. These symptoms suggest that the infection may be spreading beyond the local wound site, requiring immediate medical attention.
• Odor: An unpleasant and noticeable odor emanating from the ulcer often accompanies an infection. This odor is caused by the breakdown of tissue and the presence of bacteria, and it can be a critical indicator of the need for enhanced wound care management.
