Dressings Flashcards
How long is saline good for after opening?
24 hours
When is sterile technique used?
packing wounds, large surface wounds, severe burns, immunocompromised
What are three descriptions of dressings?
passive- bandaid
active- autolytic debridement
interactive- something that removes exudate
What happens if a wound is too moist?
maceration, additional damage, increased chance of infxn
What happens if a wound is too dry?
crust formation, lacks enzymes, no epitheliazation
What is a primary layer for dressings?
this directly contacts wound, bottom layer can be semi adherent or non adherent
What is a secondary dressing?
placed over primary layer one of two choices:
- absorbent- intermediete layer
- outer layer- secures dressing/protects wound
What is regular gauzed used for?
tunneling, undermining, highly exuding wounds- frequent dressing changes
What is benefit for gauze?
low cost and provides cushioning for wounds
What are limitations of gauze?
highly permeable, frequent changes, higher infection rate
What is impregnated gauze for?
burns, epitheliazation/granulating wounds, deep wounds, painful wounds
What are benefits of impregnated gauze?
decrease pain and trauma during changes, can increase occlusiveness of gauze
What are limitations of impregnated gauze?
high cost, minimal absorption, requires secondary dressing
What are occlusive dressings?
ability of a dressing to maintain moisture levels and able to transmit moisture vapor and gases from wound bed to atmosphere
Can occlusive dressings be used with infected wounds?
No, except for alginate
What are general benefits for occlusive dressings?
comfortable, various sizes, less time for change, fewer changes
Some providers fear a moist dressing can cause infection is this true?
No, occlusive dressings have lower infection rates than non-occ.
What is order of most occlusive to least occlusive dressings?
- hydrocolloid, hydrogel, semipermeable foam, impregnated gauze, calcium alginate, gauze
