Inflammatory Response II: Inflammatory Exudate and Tissue Repair01:24

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

5.3K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Phases of Wound Repair

6.2K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Hypersensitivities

877
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Summary

Many wound care products contain allergens that can cause allergic contact dermatitis (ACD). Clinicians should be educated on selecting products to minimize allergen exposure for patients with chronic wounds.

Area of Science:

  • Dermatology
  • Allergology
  • Wound Care

Background:

  • Patients with chronic wounds face a higher risk of developing allergic contact dermatitis (ACD).
  • ACD from wound care products is a recognized clinical issue.
  • Minimizing allergen exposure is crucial for preventing contact sensitization in this population.

Purpose of the Study:

  • To identify common contact allergens present in wound care products.
  • To inform clinicians about potential allergens in commonly used wound care items.
  • To guide the selection of wound care products with lower allergenic potential.

Main Methods:

  • A cross-referencing analysis was performed on ingredients from 267 wound care products.
  • Products were sourced from five wound care clinics across two institutions.
  • Ingredients were compared against the American Contact Dermatitis Society core allergen series 2020.

Main Results:

  • Over a third (36.3%) of analyzed wound care products contained at least one contact allergen.
  • Commonly found allergens included acrylates, propylene glycol, parabens, and fragrance.
  • Allergens were prevalent across various product types, notably medications, tapes/glues, and emollients.

Conclusions:

  • A significant proportion of wound care products harbor contact allergens.
  • Clinician awareness and education regarding ACD and product ingredients are essential.
  • Careful product selection is necessary to mitigate the risk of allergic reactions in patients with chronic wounds.
