1
Q

Define chronic wounds and explain why they may require adjunctive wound modalities.

A
  • Chronic wounds fail to respond to standard care and show stalled healing for over 30 days.
  • Adjunctive modalities can help reduce bioburden and necrotic tissue.

Q

Compare effects of the negative pole (cathode) vs. the positive pole (anode) in ES.

A
  • Cathode: decreases edema, promotes granulation, bactericidal.
  • Anode: promotes healing, coagulates protein, attracts macrophages.

Q

What are the main purposes of high-frequency vs. low-frequency US in wound care?

A

High-frequency: improves collagen deposition and contraction.

Low-frequency: debridement, reduces wound bioburden.

Q

Explain diathermy’s mechanism and effects on wound healing.

A

Uses RF energy for heating; increases circulation, fibroblast function, and nitric oxide release; contraindicated on moist wounds.

17
Q

Compare the effects and indications of UVB vs. UVC light in wound healing.

A

UVB induces inflammation and granulation

UVC is bactericidal, enhances granulation, and inactivates microorganisms.

18
Q

What are common delivery methods and contraindications for UV therapy?

A

- Delivered via LEDs or lasers;

- Contraindicated:

  • malignancy
  • DVT
  • deep vein thrombosis
19
Q

List the main purposes and effects of NPWT.

A
  • reduces edema
  • increases granulation
  • maintains moist environment
  • promotes wound contraction
  • decreases bioburden.
20
Q

Describe Negative Pressure Wound Therapy:

  • indications = ?
  • contraindications = ?
  • common settings = ?
A

  • contraindicated in necrotic or eschar wounds and exposed organs;
  • Pressure: 50-175 mmHg
21
Q

What are the setup steps and common disadvantages of NPWT?

A
  • Steps: irrigate, debride, apply foam, connect tubing, cover with drape.
  • Disadvantages: pain, mobility restriction, air-tight seal issues.
22
Q

What are the purposes and effects of HBO on wound healing?

A
  • Extracorporeal Shock Wave Therapy (ESWT): enhances microcirculation and metabolism.
  • Cold atmospheric plasma (CAP): promotes fibroblast proliferation, keratinocyte growth, and angiogenesis.
25
Q

List the main criteria for selecting a wound modality for a specific patient.

A

27
Q

Explain the role of the clinical setting and available resources in wound modality choice.

A

Availability, equipment access, and patient tolerance all influence modality choice and practicality.

28
Q

Summarize the importance of modality effects, contraindications, and overall goal for wound adjunct therapies.
