Wound Flashcards
(20 cards)
List 3 ways E-stem is thought to promote healing
Attracting appropriate cell types, activating cells by altering membrane potentials, reducing edema.
How does E-stim enhance fibroblast proliferation?
By cell attraction by polarity
What does increased calcium in fibroblast cell membranes lead to?
Exposure of insulin receptors
What voltage maximizes calcium channel opening in fibroblasts?
HVPC (60-90V)
What waveform is used for wound healing?
High Volt Pulsed Current (HVPC)
Is polarity important in HVPC for wound healing?
Yes, it is monophasic.
Which polarity is used in the early inflammatory stage of healing?
Negative polarity
Which polarity is used in the cell proliferation stage of healing?
Positive polarity.
What is the recommended current amplitude for wound healing?
Strong, but comfortable sensory
What is the typical treatment time for E-stim for wounds?
45-60 minutes
How often should E-stim be applied for wound healing?
1 time per day, 5 days per week
List 3 negative consequences of non-healing wounds
Systemic infections (sepsis), malnutrition, osteomyelitis.
Describe one option for electrode placement for wound healing.
One treatment electrode “in” or “on” the wound.
What can be used as a treatment electrode in the wound?
Saline-soaked gauze.
What are acceptable materials for electrodes?
Single-use disposable, multi-use carbon rubber, heavy-duty aluminum foil.
Describe an alternative electrode placement option
One or more treatment electrodes “around” the wound
What is a precaution regarding sensation when using E-stim for wounds?
Be careful if sensation is decreased in or around the wound
What type of electrodes should be used for wound healing?
Single patient and single-use.
Name 3 patient populations at high risk for wounds.
Patients with impaired sensation, impaired blood supply, or lacking mobility.
Which chronic wounds does CMS cover for E-stim treatment (if unresponsive to standard treatment in 30 days)?
Stage III and IV pressure ulcers, diabetic ulcers, venous stasis ulcers
