Modalitites Flashcards
Define chronic wounds and explain why they may require adjunctive wound modalities.
- 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.
What are the main challenges in research supporting wound modalities?
Challenges include:
- Patient-related variables
- Wound-related variables
- Treatment-related variables
- Research-related problems
- Manufacturer-sponsored research
List general indications for adjunctive wound modalities and considerations for selection.
- Adjunctive modalities are indicated for chronic wounds needing enhanced healing.
- Consider patient characteristics, wound location, treatment setting, and equipment.
What is the purpose of wound irrigation, and what pressures are recommended?
- Removes debris, bacteria, and exudate
- Recommended pressures are 4-15 psi
List the indications, contraindications, and common methods for wound irrigation.
- indicated for all wound types
- contraindicated in profuse bleeding
- methods include syringe or pressurized saline
Describe the effects of whirlpool therapy and list its common indications.
- softens necrotic tissue, promotes circulation, and reduces pain
- indicated for infected wounds, thick eschar, and pain relief
What are the contraindications and disadvantages of whirlpool therapy?
- Contraindicated in clean, granulating wounds and hydrophobic or seizure-prone patients.
- Disadvantages include risk of maceration and cross-contamination.
What are the effects and recommended irrigation pressures for pulsed lavage?
- facilitates debridement and improves granulation
- 4-15 psi
- includes suction to remove contaminants
List indications, precautions, and key setup considerations for pulsed lavage.
- Indicated for wounds needing debridement
- Precautions include exposed deep tissues and anticoagulant use
- Requires clean room and PPE
What are the general purposes of electrical stimulation (ES) in wound care, and which types of wounds are typically treated?
- ES promotes healing, manages inflammation, and enhances wound contraction
- Suitable for all wound depths
Compare effects of the negative pole (cathode) vs. the positive pole (anode) in ES.
- Cathode: decreases edema, promotes granulation, bactericidal.
- Anode: promotes healing, coagulates protein, attracts macrophages.
What are contraindications for ES in wound care?
Untreated osteomyelitis, malignancy, heavy metal-based topical agents, pacemakers, and reflex center wounds.
Describe the method and common settings for ES, including polarity changes.
Frequency: 120 Hz,
Intensity: 75-200 V, submotor;
Change polarity every 1-3 days; 45-60 mins, 3-5 days/week.
What are the main purposes of high-frequency vs. low-frequency US in wound care?
High-frequency: improves collagen deposition and contraction.
Low-frequency: debridement, reduces wound bioburden.
Describe the indications, methods, and precautions for traditional high-frequency US.
- Indicated for recalcitrant wounds;
- Methods include direct or immersion;
- Precautions include osteomyelitis and DVT.
