33
Q

when can an inflammatory response occur?

A
  • surgical wounds, skin injuries
  • allergies
  • autoimmune diseases
  • skin infections
34
Q

wound

A

any disruption of the integrity & function of tissues in the body

can be intentional (surgery)or accidental (cut, pressure injury, trauma)

35
Q

what actions are imperative for wound healing?

A

wound assessment & classification

36
Q

when does the inflammatory response occur for tissue trauma?

A

within 24 hours

37
Q

true or false

the inflammatory response mechanism is the same regardless of the injuring agent

A

true

38
Q

inflammatory response intensity depends on what?

A
  • extent/severity of injury
  • reactive capacity of the person
39
Q

vascular response to inflammation

A
  • increased capillary permeability, fluid moves to tissues (swelling), begins as serum fluid, tehn pulls fluid from vessels into the tissues
  • redness, heat, swelling
  • fibrinogen strengthens blood clots (prevents the spread of bacteria)
40
Q

cellular response to inflammation

A
  • neutrophils & monocyes move to injury (site of infection), increase WBC
  • exudate (fluid & leukocytes) depends on severity (local or systemic)
41
Q

clinical manifestations of local inflammation

A
  • redness
  • heat
  • pain
  • swelling
  • loss of function
42
Q

clinical manifestations of systemic inflammation

A
  • leukocytosis
  • malaise
  • nausea, anorexia
  • increased HR & RR (fever)
  • fever

occur due to the release of cytokines

43
Q

types of inflammation

3

A
  • acute
  • subacute
  • chronic
44
Q

acute inflammation

A
  • healing in 2-3 weeks, no residual damage
  • neutrophils predominant cell type
45
Q

subacute inflammation

A
  • same as acute
  • takes longer to heal

potentially affected by comorbidities

46
Q

chronic inflammation

A
  • may last for years
  • injurious agent persists/ repeated injury to site
  • lymphocytes & macrophages are predominant cell types

ex: eczema, psoriasis
* symptoms can be treated, but not cured

constant auto-immunity disorders

47
Q

health promotion for inflammation

A
  • prevention of injury
  • adequate nutrition
  • early recognition of infeciton/inflammation
  • immediate tx
48
Q

what is an early symptom of inflammation?

A

general malaise

49
Q

change in vital signs for pts with infection

A

increase in:
* temp
* HR
* RR

50
Q

fever management for infection

A
  • may not be necessary, as mild-mod fevers are usually not harmful
  • may make young/old pts more comfortable
  • fever > 104 is an emergency
51
Q

what is the final stage of inflammatory process?

A

healing

52
Q

regeneration

A

replacement of lost cells/ tissue with the same cell type

53
Q

repair

A

healing replacement with connective tissue cells, scar forms
* more complex & common
* occurs by primary, secondary, or tertiary intention

54
Q

healing by primary intention

A

normal (3 phases)

ex: c-section, sewn, healed

55
Q

healing by secondary intention

A

any trauma wound (not approximated)
* sewn the best way possible, not precise wound/scar

ex: MVC injury

56
Q

healing by tertiary intention

A

primary intention gone wrong
* must heal from the inside out

ex: c-section, didn’t report signs of infection, wound re-open/surgery

57
Q

phases of healing by primary intention

3

A
  1. initial: (3-5 days) acute inflammatory response
  2. granulation: fibroblasts secrete collagen, wound is pink & vascular, resistant to infection
  3. maturation: (begins after 7 days, lasts months/years) scar formation, fibroblasts disappear, wound becomes stronger
58
Q

process of healing by secondary intention

A

same as primary proces, but inflammatory reaction may be greater, requires debridement before healing can occur
* uneven wound edges, lots of exudate, tissue loss

59
Q

process of healing by tertiary healing

A

delayed primary inention due to delayed suturing of wound
* occurs when a contaminated wound is left open & sutured closed after the infection is controlled

60
Q

what type of wounds are healed by regeneration?

A

partial-thickness wounds

61
Q

what type of wounds are healed by repair?

A

full-thickness wounds

62
Q

what factors influence wound healing?

A
  • nutrition: protein, vitamins, sizc & copper, calories
  • tissue perfusion: O2 fuels cellular functions (blanch test)
  • infection: prolongs inflammatory response, delays collagen synthesis and epithelialization, increase in cytokines
  • age: decreased function of macrophages> delayed inflammmatory response (slower healing)
63
Q

complication of wound healing

A
  • hemorrhage: excess bleeding
  • hematoma: collection of blood under the skin
  • infection
  • dehiscence: when a wound breaks open (stiches/staples)
  • evisceration: when something comes out of the wound (body part) (this is why we splint coughs)
64
Q

skin tear

A

wound caused by friction
* partial or full thickness
* common for elderly pts (thinner skin)

65
Q

what does wound identificaiton depend on?

A
  • wound classification
  • surgical/ non-surgical
  • acute/ chronic
66
Q

when should you assess wounds?

A
  • on admission
  • Qshift (2x/day)
67
Q

when assessing wounds, what should you look for?

A
  • locaiton
  • size
  • surrounding tissue
  • wound base
  • drainage (odor, color, consistency)
  • factors that could delay healing (hemorrage, hematoma)
68
Q

what does management of wounds depend on?

A
  • type of dressing
  • extent of injury
  • character of wound
  • healing phase
69
Q

management of clean wounds

A
  • cleansing
  • closure (adhesive strips, sutures, staples)
70
Q

management of wound dressings

A

should be clean & slightly moist

71
Q

management of surgical wounds

A

sterile dressing (removed in 2-3 days)

72
Q

should antimicrobial/bacterial solution be used for wounds & dressings?

A

no
they can damage new epithelial cells & delay healing

73
Q

purpose of wound drains

A

remove excess fluid from surgical wounds

most common is Jackson-Pratt

73
Q

management of contaminated wounds

A
  • debridement is required first for healing to occur (must be converted to clean wound)
  • dressings absorb exudate & clean wound
74
Q

wound dressing purposes

A
  • protection - bacteria
  • aids in hemostasis
  • absorbs drainage/ debrides
  • thermal insulation
  • moist environment
75
Q

types of surgical dressings

A
  • gause
  • transparent film
  • hydrocolloid
  • hydrogel
  • foam
  • composite
76
Q

process of dressing changes

A
  • review previous wound assessment
  • evaluate pain> analgesics
  • describe procedure
  • remove tape
  • recognize normal healing signs
  • clean wound edges
  • date, time, initial dressing
  • document
77
Q

how to clean a wound/drain site?

A
  • clean from least contaminated>surrounding tissue
  • irrigation: allow fluid to flow from least>most contaminated
78
Q

suture/staple removal

A
  • match the number that went in
  • clip near skin, opposite of know
  • document
79
Q

steri-strips removal

A
  • don’t pull/ create tension
  • allow to fall off naturally (10 days)
  • may shower

A

may be given prophylactic antibiotcs
