Flashcards in Wound Interventions and Dressings Deck (47)
What are 2 types of wound debridement?
What is selective debridement?
Removal of ONLY non-viable tissue from a wound
What are three types of selective debridement?
What is sharp debridement?
Use of a scalpel, scissors or forceps to remove non-viable tissue or debris from the wound bed
When is sharp debridement used?
When large amounts of thick, adherent, necrotic tissue is present
What is enzymatic debridement?
Application of an enzymatic preparation to necrotic tissue to remove necrotic tissue
When is enzymatic debridement used?
Used on infected and non-infected wounds with necrotic tissue or when autolytic debridement is not effective
What is autolytic debridement?
Use of the body's own mechanisms to remove nonviable tissue
What are 4 examples of autolytic debridement?
What is the purpose of autolytic debridement?
Establishes a moist wound environment that rehydrates necrotic tissue and eschar
When is autolytic debridement not used?
On infected wounds
What is non-selective debridement?
Removal of both viable and non-viable tissues from a wound
What are the 3 most common types of non-selective debridement?
What is wet to dry dressing application?
Refers to the application of a moistened gauze dressing over an area of necrotic tissue
Describe the debridement process via wet to dry dressing application.
1. Apply the moistened gauze over the wound
2. Let gauze dry completely
3. Remove gauze (necrotic tissue will be adhered to gauze)
What is wound irrigation?
Removal of necrotic tissue from the wound bed using pressurized fluid
What is an example of wound irrigation?
What is the most common form of hydrotherapy?
What are 3 potential side effects of hydrotherapy?
1. Maceration of viable tissue
2. Edema from dependent LE positioning
What is negative pressure wound therapy (NPWT)?
Non-invasive modality that involves placing a sterile foam dressing over the wound and sealing it with an airtight secondary dressing which is attached to a vacuum pump.
When is negative pressure wound therapy indicated?
Indicated for wounds that cannot be closed by primary intention
What are 5 contraindications to using negative pressure wound therapy? (NPWT)
1. Malignancy within the wound
2. Insufficient vascularity for wound healing
3. Large amounts of necrotic tissue
4. Uncontrolled pain
5. Untreated osteomyelitis
What is hyperbaric oxygen?
Refers to the inhalation of 100% oxygen at a pressure greater than 1 atmosphere to reduce edema and hyper oxygenating tissue
When is hyperbaric oxygen indicated? (5)
What are growth factors?
Derived from naturally occurring protein factors. Promote healing by stimulating the activity of specific cell types
When is the use of growth factors indicated?
To treat neuropathic ulcers extending into or through subcutaneous tissue
When is the use of growth factors contraindicated?
Contraindicated for wounds closed by primary intention
What is the difference between primary and secondary dressings?
Primary = dressings that come in direct contact with the wound
Secondary = dressings that are placed directly over the primary dressing for protection/absorption etc.
What are 6 types of wound dressings?
