ES for wound healing Flashcards
uses of ES in terms of tissue healing
tissue regeneration
edema control
improved circulation
what are the 4 phases of the wound healing process
hemostasis
inflammation
proliferation
maturation
what happens in hemostasis
to control bleeding
what happens in inflammation
for cleaning of wound and inc BF; phagocytosis, lymphocytes ganun
what happens in proliferation
tissue repair ganin
fibroblasts - granulation tissues
angiogenesis - new BV formation
epithelial cells - reepithelialization
what happens in remodelling
ensures tensile strength - reorientation of fibers
types of currents used in wound healing
low-intensity direct current
high voltage pulsed galvanic current
russian currents/MFBurstAC
biphasic pulsed currents
what type of ES does LIDC use
monophasic na cont or pulsed c modulation of polarity reversal
uses constant current
peak amplitude of LIDC
999 uA or < 1mA = low intensity
what type of ES does HVPGC use
twin peak of monophasic pulses na 10-100 usec pulse duration
uses constant voltage
peak voltage of HVPGC
500V
what type of ES does MFBurstAC use
cont sine wave about 2500-50000 Hz c 50 bursts/sec
polyphasic time-modulated AC
use of BPC
when muscle contraction is required to reduce edema
exp the concept of normal skin battery
it is the DC bioelectrical system to maintain tissue health - negative sa labas and positive inside
where is skin batter found
betw stratum corneum and dermis
what happens to skin battery when there is a wound
normal skin batt is stopped c wounds = current flow shift to injured area = current of injury
negative napupunta sa loob
relate ES to normal skin battery c wound
microcurrent/LIDC or HVPGC mimics and amplifies the weak human skin batt at wound site
exp the concept of galvantoaxis
attraction of cells to the opposite electrical charge
hence ES promotes tissue healing by ionic effects - attracts/repels charged particles
so imp to know polarity of cells and wound ganun
discuss effect of ES on inflammatory phase for cellular and systemic level
cellular: macrophage migration and activation and antibacterial effect
systemic: faster inflammatory phase and vasodil or inc O2
discuss effect of ES on proliferation and remodelling phase for cellular and systemic level
basta helps in new tissue formation and blood vessels; makes it faster
what cells migrate towards an anode
anode is + so it will attract -
neutrophils
vascular endothelial cells
macrophages
what cells migrate towards an cathode
cathode is - so it will attract +
monocytes
fibroblasts
epidermal cells
discuss galvantoaxis on inflammatory phase
phagocytosis and autolysis
(-) macrophages and neutrophils
discuss galvantoaxis on proliferative phase
fibroplasia
(+) fibroblasts
discuss galvantoaxis on maturation phase
wound contraction
(+) keratinocytes and epidermal cells
type of electrode for inflammation phase
anode (+)
type of electrode for proliferative and maturation phase
cathode (-)
physiological effect of ES on inflammation phase
initiates wound repair process
inc BF
promotes phagocytosis
enhances tissue oxygenation
controls infection
solubilizes blood products and necrotic tissue
physiological effect of ES on proliferative phase
stimulates fibroblasts and epithelial cells
stimulates DNA and protein synthesis
increases ATP
improves membrane transport
produces better collagen matrix org
stimulates wound contraction
physiological effect of ES on maturation phase
stimulates epidermal cell reproduction and migration
produces smoother thinner scar
physiological effect of ES on germicidal effect
due to anode
inhibits growth action of microogranisms
E. coli
pseudomonas aeruginosa
staphylococcus aureus
is edema due to inflammation indic/contra for ES
indicated
is edema due to immobility indic/contra for ES
indicated
is edema due to systemic disorders indic/contra for ES
contraindicated
physiological effect of ES on edema due to inflamm
cathodes repels (-) proteins back to BV and reduces size of vessel walls
only retards edema formation; cant dec
type of ES used to control edema due to inflamm
HVPGC at sensory level stimulation
physiological effect of ES on edema due to immob
muscle contraction = pumping effects
ES used together c limb elevated followed by compression
physiological effect of ES on improving circulation
inc circulation d/t muscle contraction = pumping
pero conflicting evidence pa yan
indication of ES in terms of wound healing
healing of burns, ulcers and surgical wounds
infection
retardation and reduction of edema
inc BF
discuss electrode placement for wound healing
if wound is closed or scar formed - over the wound
if open pa - around the wound
discuss infection control for ES
wrap electrodes c sterile gauze pads saturated c normal saline
discuss temp of electrode for wound healing
should be warmer that the wound but should not exceed 38°C
type of ES for wound healing
LIDC and HVPGC
type of ES for edema control due to inflamm
