Wound and Bone Healing Flashcards
53 year old female with an infected diabetic foot ulcer. which therapeutic modality is contraindicated in this patient?
moist heat pack
What are the 4 types of skin ulcers*
-venous stasis
-arterial
-diabetic
-decubitus
what is the main cause of failed wound healing?
lack of blood flow
venous stasis ulcers*
venous insufficiency
aterial ulcers*
narrowing arteries
diabetic ulcers*
small vessel disease
decubitus ulcers*
pressure sores
what interferes with wound healing?
mostly intrinsic factors
person: smoking, obesity, nutrition, age
environ: blood flow, o2
what are the stages of healing*
hemostasis
inflammatory
proliferative
maturation
hemostasis*
clotting
inflammatory*
help prevent infection
proliferative*
pink or red granulation, does not bleed easily
dark tissue, easy bleeding can be a sign of infection
maturation*
remodeling of collage
3 weeks after injury and lasts up to one year
healthy epidermis has a ______ charge, healthy dermis is _________ charged. Natural current difference __________ healing and external stimulus can enhance healing
what is this theory?
negative
positive
stimulates
current of injury theory
what triggers would healing? what enhances healing? what do chronic open wounds lack?
initial polarity
maintaining this polarity
this polarity
what kind of current do we want to use for wound and bone healing
high voltage pulsed current
what are the two ways electrotherapy try to do to improve wound healing
improve vascular status
localized edema control
what is the most common chronic non-healing wound?
diabetic ulcers
many lead to amputation
often recurrent, in remission, not fully healed
How do you handle wound healing if infection is present?*
cathode (black) over the dressing/wound
How do you handle wound healing if no infection is present?*
aimed at prevention
anode (red/+) of DC stimulator over wound
what kind of muscle contraction do we want for edema control settings?
rhythmic
what edema control settings do we want?
pulse or burst modulated AC
- >100 pulse duration
-want rhythmic muscle contraction
high voltage pulsed current
- 2-50us
-90% of motor threshold
30 min treatment every four hours
duration of treatment for wound healing and LADC
2 hours twice a day
duration of treatment for wound healing and HVPC
30 mins twice a day
