Types of Wound Debridement

Types of Wound Debridement

Autolytic Debridement:

Description:

  • Autolysis uses the body's own enzymes and moisture to re-hydrate, soften and finally liquefy hard eschar and slough. Autolytic debridement is selective; only necrotic tissue is liquefied. It is also virtually painless for the patient. Autolytic debridement can be achieved with the use of occlusive or semi-occlusive dressings which maintain wound fluid in contact with the necrotic tissue. Autolytic debridement can be achieved with hydrocolloids, hydrogels and transparent films.

Best Uses:

  • In stage III or IV wounds with light to moderate exudate

Advantages:

  • Very selective, with no damage to surrounding skin.
  • The process is safe, using the body's own defense mechanisms to clean the wound of necrotic debris.
  • Effective, versatile and easy to perform
  • Little to no pain for the patient

Disadvantages:

  • Not as rapid as surgical debridement
  • Wound must be monitored closely for signs of infection
  • May promote anaerobic growth if an occlusive hydrocolloid is used

Enzymatic Debridement:

Description:

  • Chemical enzymes are fast acting products that produce slough of necrotic tissue. Some enzymatic debriders are selective, while some are not.

Best Uses:

  • On any wound with a large amount of necrotic debris.
  • Eschar formation

Advantages:

  • Fast acting
  • Minimal or no damage to healthy tissue with proper application.

Disadvantages:

  • Expensive
  • Requires a prescription
  • Application must be performed carefully only to the necrotic tissue.
  • May require a specific secondary dressing
  • Inflammation or discomfort may occur

Mechanical Debridement:

Description:

  • This technique has been used for decades in wound care. Allowing a dressing to proceed from moist to wet, then manually removing the dressing causes a form of non-selective debridement.
  • Hydrotherapy is also a type of mechanical debridement. It's benefits vs. risks are of issue.

Best Uses:

  • Wounds with moderate amounts of necrotic debris

Advantages:

  • Cost of the actual material (ie. gauze) is low

Disadvantages:

  • Non-selective and may traumatize healthy or healing tissue
  • Time consuming
  • Can be painful to patient
  • Hydrotherapy can cause tissue maceration. Also, waterborne pathogens may cause contamination or infection. Disinfecting additives may be cytotoxic.

Surgical Debridement:

Description:

  • Sharp surgical debridement and laser debridement under anesthesia are the fastest methods of debridement.
  • They are very selective, meaning that the person performing the debridement has complete control over which tissue is removed and which is left behind
  • Surgical debridement can be performed in the operating room or at bedside, depending on the extent of the necrotic material.

Best Uses:

  • Wounds with a large amount of necrotic tissue.
  • In conjunction with infected tissue.

Advantages:

  • Fast and Selective
  • Can be extremely effective

Disadvantages:

  • Painful to patient
  • Costly, especially if an operating room is required
  • Requires transport of patient if operating room is required.

Ulcer Documentation

Ulcer Documentation

After assessing a wound, proper documentation is necessary for medical, legal and reimbursement reasons. A photograph of the wound is the most reliable documentation. Your charting should include the following information on each wound care visit:

  • Patient's name and date of visit
  • Vital signs - temp., pulse, respiration, blood pressure
  • Are the dressings intact? - (wet, dry, loose, clean, dirty)
  • Strikethrough - Is there drainage on the outside of the dressing material?
  • Location of wound - foot, leg, thigh, sacrum, elbow, shoulder, right, left, dorsal, plantar, medial, lateral, anterior, posterior, etc.
  • Size - length, width and depth measured in centimeters. (use a sterile cotton tip applicator to measure depth). DO NOT CROSS CONTAMINATE WOUNDS by using the same gloves, instruments, measuring devices, etc. if the patient has multiple wounds. Based on previous measurements, is the wound improving, deteriorating or remaining stagnant.
  • Tracking - defined as skin overhanging a dead space
  • Undermining - look for skin that overhangs the wound's edges
  • Drainage - Is there drainage on the contact layers of the dressing? What does it look like (serous, purulent, bloody, green, yellow, clear, thick, etc.) Is the drainage a breakdown of the wound dressing (like a hydrocolloid) or actual drainage from the wound? Yellow purulent drainage could indicate staphylococcus involvement. Green drainage could indicate pseudomonas involvement. Estimate the amount of drainage present.
  • Odor - Is there any odor from the wound? This can offer a great deal of information on which organism may be contaminating or infecting a wound. Fruity smell points toward staphylococcus organisms. Foul odor (fecal like) points toward gram negative bacteria.
  • Necrotic tissue - What percentage of the wound appears to be necrotic tissue. Necrotic tissue should be considered as any tissue that is not beefy red and granular. Where is the necrotic tissue? Draw a small diagram.
  • Infection - Is the wound red (or streaking redness), hot and swollen? Is there soreness out of proportion to what should be present given the patient's medical history and the progression and etiology of the wound? Infection should be assessed both clinically and with the help of lab data such as vitals and WBC count.
  • Stage pressure ulcers - refer to the section on staging pressure ulcers for a complete review. In short, an ulcer with an intact eschar should be noted as unstageable due to eschar formation. I strongly recommend that you DO NOT reverse stage a healing ulcer. For example, an ulcer initially documented as a stage 4 should not be documented as a stage 2 or a stage 1 as it heals. The reason is simple. Skin over a healed ulcer is only 70 - 80 percent as strong as undamaged skin. A new health care professional on the case may look at the latest notes and only see a stage 2 in the assessment and not realize that this patient is at high risk. I like to document that the wound is a healing stage 4 ulcer.
  • Classify non pressure ulcers - use Wagner classification for foot ulcers. Use "full thickness" or "partial thickness" phrasing to document other types of ulcers. Wagner Classification is as follows:
    • Grade 0 - Pre-ulcerative lesion, healed ulcers, presence of bony deformity
    • Grade 1 - Superficial ulcer without subcutaneous tissue involvement
    • Grade 2 - Penetration through the subcutaneous tissue (may expose bone, tendon, ligament, or joint capsule)
    • Grade 3 - Osteitis, abscess, or osteomyelitis
    • Grade 4 - Gangrene of the forefoot
    • Grade 5 - Gangrene of the entire foot
  • Past treatment - Note the past treatments and any changes in products. This will help new health care professionals on the case. Products that may not have produced the desired results won't be accidentally duplicated.
  • Current treatment - Document the type of irrigation, products and secondary dressings used during the dressing change.
  • Signature - Sign the bottom of the note.
  • Follow up - Contact the appropriate doctor, nurse, therapist or other health care professional to discuss your findings, especially if there is deterioration.
