25
Q

Describe the step-by-step procedure to sharp debridement

A

1) prepare the patient for debridement
2) explain the specific procedure to the patient
3) open necessary equipment and supplies
4) for selective sharp debridement, silver nitrate sticks and/or an absorbable gelatin sponge should be available
5) ensure adequate pain control
6) don clean gloves
7) identify devitalized tissue, foreign material, and debris to be debrided
8) remove as much of these tissues/material as possible applying tension and using a layered approach
9) rinse the wound with saline
10) assess changes in wound status and perform any necessary wound measurements
11) dispose of sharp instruments and infectious waste
12) remove and dispose of soiled gloves
13) don clean gloves
14) apply wound dressing
15) remove and dispose of soiled gloves
16) initial and date wound dressing
17) wash hands
18) provide any necessary posttreatment instructions
19) complete documentation

28
Q

What is the key to performing sharp debridement?

A

ensure that the scalpel and scissors are PARALLEL to the surface when debriding

29
Q

Which form of debridement is the least invasive and the least painful?

A

Autolytic

30
Q

Describe Autolytic debridement

A

Uses the body’s own (endogenous) enzymes to digest necrotic tissue by applying a moisture-retentive dressing, such as hydrogel, semipermeable foam, or hydrocolloid, and leaving it in place for several days

31
Q

What are the indications for autolytic debridement?

A
  • All wounds with necrotic tissue
  • Patients who cannot tolerate other forms of debridement
  • Commonly used in home or long-term care settings
32
Q

What are the 2 contraindications to autolytic debridement?

A
  • Infected or deep cavity wounds

- Wounds that require sharp or surgical debridement

33
Q

What are the 2 conditions in which autolytic debridement can be terminated?

A
  • favor of alternative methods

- if necrotic tissue fails to decrease in expected amount of time (2 weeks)

34
Q

What is an important first step to autolytic debridement when eschar is present?

A

Crosshatch the eschar with a scalpel

35
Q

How large should the moisture-retentive dressing be in comparison to the wound?

A

approximately 2 cm larger

36
Q

How long does the dressing stay on during autolytic debridement?

A

72-96 hours

37
Q

What is imperative to protecting the periwound area?

A

apply a skin sealant to prevent maceration or fungal infection

38
Q

What is enzymatic debridement?

A

the use of a topical exogenous enzyme to remove devitalized tissue

39
Q

What are the 3 main types of substrate-specific exogenous enzymes?

A
  • proteolytics
  • fibrinolytics
  • collagenases

*Collagenase is the only enzyme currently FDA approved

40
Q

What are the pros and cons to enzymatic debridement?

A
  • Requires less skill than sharp or surgical debridement
  • Less painful than other methods
  • Can be expensive
41
Q

What are the 3 indications for enzymatic debridement?

A
  • Infected and uninfected wounds with necrotic tissue
  • Patient cannot tolerate sharp debridement
  • Appropriate in-home or long-term care
42
Q

What are the 5 contraindications to enzymatic debridement?

A
  • Wounds being autolytically debrided
  • Wounds with exposed deep tissues
  • Facial burns
  • Calluses
  • Wounds free of necrotic tissue
43
Q

When should enzymatic debridement be terminated?

A
  • Once satisfactory debridement has occurred

If necrotic tissue fails to decrease in expected amount of time

44
Q

Similar to autolytic debridement protocol what is a necessary first step to enzymatic debridement when eschar is present?

A

crosshatch the eschar

45
Q

What are the 3 forms of nonselective debridement?

A
  • mechanical
  • biological
  • surgical
46
Q

Describe mechanical debridement

A

Involves the use of force to remove devitalized tissue, foreign material, and debris from a wound bed

47
Q

What are 7 examples of mechanical debridement?

A
  • wet to dry dressings
  • scrubbing
  • wound cleansing
  • wound irrigation
  • pulsatile lavage
  • whirlpool
  • hydrogen peroxide
48
Q

Describe how wet to dry dressings work

A

Apply a single layer of fluffed saline-moistened gauze to a necrotic wound, covering with more gauze, and then allowing the dressing to dry for 8-24 hours. As the dressing dehydrates, the gauze adheres to the wound bed, trapping wound exudate and debris within the interstices. When the dressing is dry, it is torn away at a right angle from the wound surface, thus lifting any material adhering to the gauze off of the wound bed.

49
Q

What is the only condition in which wet to dry dressings are indicated?

A

wounds with 100% devitalized wound bed

50
Q

What are the recommendations for wound scrubbing?

A

Use a high-porosity sponge and as little force as possible to minimize trauma

51
Q

What type of wounds is scrubbing best used for?

A

highly contaminated superficial wounds such as road rash

52
Q

Define wound cleansing

A

The delivery of a wound cleanser to the wound surface using mechanical force to remove lightly adhered necrotic tissue, debris, and bacteria

53
Q

What is a wound cleanser?

A

A commercially available solution that commonly contains surfactants, substances that lower the surface tension of loose particulate matter on the wound bed

54
Q

What are the drawbacks to wound cleansing?

A
  • it is not FDA regulated
  • it is nonselective
  • not efficient at debriding partial or full-thickness wounds
55
Q

In wht type of wound may wound cleansing be used/considered?

A
  • pressure ulcers with debris, infection, or high bioburden

- May be indicated for acute, minor integumentary injuries

56
Q

Can wound cleansing be used for a long period of time?

A

No

57
Q

What is biological debridement?

A

the use of maggots to debride necrotic tissue

58
Q

What is an advantage that biological debridement has over autolytic and enzymatic debridement?

A

It is faster

59
Q

When is surgical debridement indicated?

A
  • in the presence of ascending cellulitis and/or osteomyelitis
  • extensive necrotic wounds
  • wounds with extensive undermining
  • when necrotic tissue is near vital organs and structures
  • when the patient is septic
  • presence of gas gangrene
60
Q

What are the 2 contraindications for surgical debridement?

A
  • Patients who are unlikely to survive procedure

- Patients with palliative care plans

61
Q

Describe the basic procedure behind surgical debridement

A
