Wound Care Flashcards
Acute wound
wound follows an orderly and timely healing process, such as surgical incision
Chronic wound
wound does not heal easily and the skin does not soon return its normal appearance and function, such as pressure ulcer
Primary intention
wound with little tissue loss
such as incision
Secondary intention
wound involving tissue loss, becomes filled by scar tissue
such as burn, pressure injury
Tertiary intention
delayed primary closure
wound left open and then closed after risk of infection is resolved
Phases of partial thickness wound repair
Inflammatory response
Epithelial proliferation and migration
Re-establishment of epidermal layers
Phases of full thickness wound repair
Inflammatory phase (reaction) Proliferation phase (regeneration) Remodelling (maturation)
During healing, wound is replaced by
Granulation tissue
Wound assessment includes..
6
- Wound appearance
- Character of wound drainage
- presence of drains (jackson-pratt, hemovac, penrose)
- wound closure
- palpation of wound
- pain
What does presence of infection look like?
swelling, purulent, foul odor
sometimes, fever
What should the nurse look for? nursing diagnosis
- impaired skin integrity
- impaired tissue integrity
- impaired physical mobility
- risk of impaired skin integrity
- risk of infection
- pain
What are some interventions to promote wound healing?
- wound dressing care
- debridement
- irrigating and packing wounds
- other modalities (nutrition)
- application of bandages
Name some purposes of wound dressing
- protect from microorganisms
- aid in hemostasis
- absorb drainage
- support wound
- prevent patient from seeing the wound
- promote thermal insulation
- provide moist environment for wound bed
What are the three layers of dressing?
Contact layer
Absorbent layer
Protective layer
Principles for irrigating a wound
- done to remove debris or exudate
- fluid should flow out
- least to most contaminated
- low pressure
When swabbing wound for culture, where should one swab?
healthiest looking tissue, NOT pus or exudate
Maceration
wound in contact with moisture for too long and becomes cold, wrinkly, soft and soggy to the touch
What are some functions of bandages?
- create pressure
- immobilize body part
- support wound
- reduce edema
- secure dressing
Hemorrhage
excessive bleeding
Dehiscence
edges start to fall part, layers of skin and tissue separate
Risk behaviours that made cause dehiscence
coughing, vomiting
Evisceration
protrusion of visceral organs though wound opening, an emergent condition
Fistulas
abnormal passage between two organs (i.e. fourth degree laceration during labour)
Initiative to prevent Surgical Site Infections
- perioperative antimicrobial coverage
- appropriate hair removal
- maintenance of perioperative glucose control
- perioperative normothermia
