1

What are 7 modalities and physical agents than can be used to enhance wound healing?

- Wound irrigation
- Whirlpool
- Pulsed lavage
- Electrical stimulation
- Ultrasound
- Negative pressure wound therapy
- Hyperbaric oxygen

2

What can be defined as the use of fluid to remove loosely adhered debris, bacteria, exudate, draining residue and residual topical agents?

Wound Irrigation

3

What are 3 advantages to wound irrigation?

- Facilitates debridement
- Assists with achieving and maintaining a moist wound environment
- Enhances wound healing

4

Irrigation after whirlpool removes _ times more bacteria than whirlpool alone

4

5

Wound irrigation is an acceptable intervention for all types of wounds and is the only direct wound intervention for what type of wound?

healing granular wounds

6

In what type of wound is irrigation contraindicated?

Wounds with active, profuse bleeding

7

Wound irrigation should use _-__ psi of pressure

4-15

8

Recent recommendations for irrigation suggest that pressures between __-__ psi are most effective for preventing infection

10-15

9

What are 6 advantages to wound irrigation?

- simple
- quick
- inexpensive
- effective
- can use for wound in any location
- can be used in any setting

10

What is the main disadvantage to wound irrigation?

Irrigant runoff may soil bed lines or patient clothing, which may result in the clinician using less irrigant solution than necessary, making the treatment less effective

11

What are 3 alternatives to wound irrigation?

- Soak wound with saline-moistened gauze
- whirlpool
- pulsed lavage

12

Whirlpool is a form of _______ (selective/nonselective) mechanical debridement

nonselective

13

What are the 7 main purposes of whirlpool?

- debrides loosely adherent devitalized tissues, foreign debris, and surface bacteria
- softens necrotic tissue and eschar
- hydrates the wound bed and promotes moist wound healing
- promotes circulation
- associated with decreased patient pain complaint during wound care procedures
- eases ROM for patients with burn injuries
- can help soak off adherent wound dressings

14

Whirlpool is indicated in what 4 types of wounds?

- infected wounds
- nondraining wounds
- wounds with thick eschar
- wounds with loosely necrotic tissue or thick exudate

15

Whirlpool is contraindicated in what 4 types of wounds?

- Clean, granulating, or epithelializing wounds
- Edematous, draining, or macerated wounds
- Wounds with tunneling, undermining, skinfolds that can’t be effectively irrigated
- Active bleeding wounds

16

What should you be cautious of when treating arterial insufficiency ulcers with whirlpool?

lower the temperature

17

In what type of patients is whirlpool contraindicated?

- patients with edema or lymphedema
- incontinent patients
- patients who are hydrophobic, confused, combative, with seizures
- patients with multiple open wounds

18

__% of burn units using whirlpool therapy use the immersion method

81

19

Small whirlpools should be filled with water between __ to __ degrees Fahrenheit. Larger whirlpools need to be slightly warmer, but should never exceed ___ degrees

92-98

102

20

Whirlpool treatments should be completed in __-__ minutes

10-20

21

What are 3 advantages to whirlpool treatment?

- provides a comfortable environment to perform ROM exercises
- promotes moist wound healing
- available in most clinical settings

22

What are 4 disadvantages to whirlpool treatment?

- the irrigation pressure cannot be calibrated
- there is potential for maceration, edema, and cross-contamination
- time intensive for setup and cleanup
- expensive

23

What can be defined as the delivery of wound irrigant under pressure by an electrically powered device?

Pulsed Lavage

24

What are the 4 positive effects of pulsed lavage?

- Irrigates wound bed with precisely calibrated pressure
- Assist with obtaining/maintaining moist wound environment
- Facilitates debridement
- May enhance granulation tissue formation, epithelialization, and tissue perfusion

25

In what type of wounds is pulsed lavage indicated?

- arterial insufficiency wounds
- venous insufficiency wounds
- diabetic ulcers
- pressure ulcers
- small burns
- surgical wounds
- wounds with tunneling/undermining

26

When is pulsed lavage contraindicated?

- in wounds with exposed arteries, nerves, tendons, capsules, or bone
- on facial wounds
- recent grafts or surgical procedures
- wounds that are actively bleeding

27

Patients with a _____ allergy should not be treated with pulsed lavage

latex

28

What are 3 situations in which pulsed lavage should be used with caution?

- patients taking anticoagulants because of the potential for hemorrhage
- insensate patients to decrease the risk of unperceived trauma
- patients with deep tunneling wounds to prevent damage from the probing wound tip

29

If the pulsed lavage pressure is greater than 15 psi what is the risk?

increased bacteria penetration into wound tissues

30

Depending on the wound size and severity there should be anywhere around ____-____ mL of irrigant in the irrigant reservoir and should be between ___-___ degrees Fahrenheit.

1000-3000

102-106
