Final: E-Stim for Wounds Flashcards
What are the four mechanisms underlying electrical currents
- Galvanotaxis to attract appropriate cell types
- Activate cells by alerting cell membrane function
- Enhance antimicrobial activity
- Enhance circulation
Which type of cell does electrical stimulation activate?
fibroblasts
Electrical stimulation activates fibroblasts which enhances cell _____ and their production of _____.
replication; collagen
Electrical stimulation promotes (epidermal/dermal) and lymphocyte migration and function
epidermal
Electrical stimulation promotes epidermal and ____ migration and function
lymphocyte
True or False:
AC does not kill bacteria
true
Antimicrobial effects- HVPC and DC both (do not/can) kill bacteria
can
What two currents can kill bacteria
HVPC and DC
Which type of current does NOT kill bacteria
AC (alternating current)
Is the voltage needed to kill microbes feasible in a clinical setting?
no
Although voltage needed to kill microbes is not feasible in the clinical setting, more tolerable voltage can (enhance/reduce) the antibiotic in the destruction of ______
enhance, biofilm
Which term describes the movement of cells in response to the electrical field
galvanotaxis
_____ is the movement of cells in response to the electrical field
galvanotaxis
The rule of thumb regarding polarity and wounds states that
(positive/negative) electrodes promotes healing of inflamed or infected wounds and
(positive/negative) electrodes promote healing of wound without inflammation
negative; positive
In regards to the rule of thumb of polarity and wounds, when would you use negative electrodes
To promote healing of inflamed or infected wounds
In regards to the rule of thumb of polarity and wounds, when would you use positive electrodes
To promote healing of wounds without inflammation
Studies support that e-stim facilitates would ____ of chronic wounds
healing
How does e-stim facilitate wound healing? (Hint: There’s three reasons)
- Improves percentage and weekly change in ulcer size
- Increases likelihood of complete wound closure
- Saves health care costs
E-stim can be used to control ____
edema
When using e-stim to control edema due to inflammation, the (positive/negative) polarity HVPC retards formation of (acute/chronic) edema
negative; acute
True or False:
When treating a patient with e-stim due to inflammation, the area being treated will be cold, pale, and swollen
false it will hot, red, and swollen.
Edema due to a lack of muscle control will be cold, pale and swollen
When using e-stim to treat a patient with edema due to inflammation, the negative charge repels (negative/positive) charged serum proteins
negative
When using e-stim to control edema due to inflammation, roughly ____% reduction will be shown; similar magnitude to _____ or cold water immersion
50%; ibuprofen
When using e-stim to control edema due to lack of muscle control, (unhealthy/healthy) muscles contract to promote ___ return from periphery
healthy; fluid
