Flashcards in E Stim Tissue Healing & Iontophoresis Deck (55)
1

three components of inflammatory stage of wound healing

hemostasis, phagocytosis, autolysis, fibroblast migration

2

three components of proliferation stage of wound healing

collagen synthesis, angiogenesis, epithelialization, wound contraction

3

components of maturation stage of wound healing

collagen lysis, collagen replacement

4

a couple things that impede wound healing

smoking, infection, stretch/pressure, malnutrition other medications

5

chronic wound that is an Area of local tissue loss due to prolonged tissue compression between boney prominences and external surfaces

pressure sore

6

compression of tissues can cause blank

necrosis

7

stage of pressure sore with non blanchable erythema of intact skin

1

8

stage of pressure sore with full thickness skin loss including damage to subcutaneous tissue

3

9

stage of pressure sore with full thickness skin loss with destruction or damage to muscle, bone, or support structures

4

10

stage of pressure sore with partial thickness skin loss to epidermis, dermis, or both

2

11

chronic wound due to area of local tissue loss due to arterial blood supply deficiency

arterial insufficiency ulcers

12

chronic wound due to area of local blood loss due to deficiency in venous drainage

venous insufficiency ulcers

13

chronic wound that is an area of local tissue loss due to sensory neuropathy and arterial blood supply deficiency

diabetic ulcers

14

ionic movement electricity electrophysical effect

electrokinetic

15

example of electrokinetic effect

depolarizing excitable membrane

16

blank of charged particles produces heat

microvibration

17

high skin impedence blank thermal effect

increases

18

effect of wound healing that affects macrophages in the inflammatory phase, fibroblasts during proliferation, and myofibroblasts during maturation

galvanotaxis

19

types of currents for wound healing

low intensity dc, continuous dc, high volt pulsed, twin-peak monophasic pulse, rectangular monophasic pulse, biphasic pulse

20

outside of skin has blank charge

negative

21

inside of skin has blank charge

positive

22

with injury, outside of skin has blank charge

positive

23

with injury, inside of skin has blank charge

negative

24

blank is most normally used over wound, but blank is used if infected with staph aureus

cathode, anode

25

anode attracts blank and blank

macrophages, neutrophils

26

cathode attracts blank and stimulates these two

fibroblasts, myofibroblasts, keratinocytes

27

cathode will blank tissue

soften

28

anode will stimulate blank

epithelialization

29

wound healing protocol based on electrochemical response in tissues being stimulated

4

30

wound healing protocol based on type of healing clinician wants to induce

3

31

cathode blank blood flow

increases

32

anode blank blood flow via blank

decreases, vasoconstriction

33

ionized medication must be placed under electrode of blank charge

same

34

without iontophoresis, drug must be delivered via

passive diffusion

35

The introduction of medicinal ions into the body tissues by means of a low voltage direct electromotive force (DC current)

iontophoresis

36

iontophoresis occurs due to the electrostatic blank of an ion by a similarly charged electrode

repulsion

37

iontophoresis occurs due to increasing the permeability of the blank

stratum corneum

38

temporary production of water soluable pores in the skin

electroporation

39

as water is carried throught he skin, it can carry other objects dissolved in it along with it.

electroosmosis

40

current that produces a buildup of ions under the electrodes producing chemical reactions and altering skin pH

direct

41

negative electrode has blank ions which makes a blank reaction

sodium hydroxide, alkaline

42

positive electrode has blank ions which makes a blank reaction

hydrochloric acid, acidic

43

depth of penetration during iontophoresis

1-3 mm

44

depth of penetration after iontophoresis (12-24 hrs)

1.5 cm

45

conraindications of iontophoresis

metal near skin, recent scars, dvt

46

drug must be in blank state to blank

ionized, permeate skin

47

any blank can be used for iontophoresis

electrode

48
