Q

what happens to skin battery when there is a wound

A

normal skin batt is stopped c wounds = current flow shift to injured area = current of injury

Q

exp the concept of galvantoaxis

A

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

Q

discuss effect of ES on inflammatory phase for cellular and systemic level

A

cellular: macrophage migration and activation and antibacterial effect

systemic: faster inflammatory phase and vasodil or inc O2

20
Q

discuss effect of ES on proliferation and remodelling phase for cellular and systemic level

A

basta helps in new tissue formation and blood vessels; makes it faster

21
Q

what cells migrate towards an anode

A

anode is + so it will attract -

neutrophils
vascular endothelial cells
macrophages

22
Q

what cells migrate towards an cathode

A

cathode is - so it will attract +

monocytes
fibroblasts
epidermal cells

23
Q

discuss galvantoaxis on inflammatory phase

A

phagocytosis and autolysis

(-) macrophages and neutrophils

24
Q

discuss galvantoaxis on proliferative phase

A

fibroplasia

(+) fibroblasts

25
Q

discuss galvantoaxis on maturation phase

A

wound contraction

(+) keratinocytes and epidermal cells

26
Q

type of electrode for inflammation phase

A

anode (+)

27
Q

type of electrode for proliferative and maturation phase

A

cathode (-)

28
Q

physiological effect of ES on inflammation phase

A

initiates wound repair process

inc BF

promotes phagocytosis

enhances tissue oxygenation

controls infection

solubilizes blood products and necrotic tissue

29
Q

physiological effect of ES on proliferative phase

A

stimulates fibroblasts and epithelial cells

stimulates DNA and protein synthesis

increases ATP

improves membrane transport

produces better collagen matrix org

stimulates wound contraction

30
Q

physiological effect of ES on maturation phase

A

stimulates epidermal cell reproduction and migration

produces smoother thinner scar

31
Q

physiological effect of ES on germicidal effect

A

due to anode

inhibits growth action of microogranisms

E. coli
pseudomonas aeruginosa
staphylococcus aureus

32
Q

is edema due to inflammation indic/contra for ES

A

indicated

33
Q

is edema due to immobility indic/contra for ES

A

indicated

34
Q

is edema due to systemic disorders indic/contra for ES

A

contraindicated

35
Q

physiological effect of ES on edema due to inflamm

A

cathodes repels (-) proteins back to BV and reduces size of vessel walls

only retards edema formation; cant dec

36
Q

type of ES used to control edema due to inflamm

A

HVPGC at sensory level stimulation

37
Q

physiological effect of ES on edema due to immob

A

muscle contraction = pumping effects

ES used together c limb elevated followed by compression

38
Q

physiological effect of ES on improving circulation

A

inc circulation d/t muscle contraction = pumping
pero conflicting evidence pa yan

39
Q

indication of ES in terms of wound healing

A

healing of burns, ulcers and surgical wounds

infection

retardation and reduction of edema

inc BF

40
Q

discuss electrode placement for wound healing

A

if wound is closed or scar formed - over the wound

if open pa - around the wound

41
Q

discuss infection control for ES

A

wrap electrodes c sterile gauze pads saturated c normal saline

42
Q

discuss temp of electrode for wound healing

A

should be warmer that the wound but should not exceed 38°C

43
Q

type of ES for wound healing

A

LIDC and HVPGC
