A

partial thickness wound: epithelialization

full thickness wound: granulation tissue, contracture

21 days to 2 years

-only happens with full thickness wounds

56
Q

timeline for phases of partial thickness wounds

  • hairline scar
  • decreased infection and scarring
58
Q

Secondary Intention wound

A
  • gaping irregular wound
  • granulation
  • epithelium grow over scar
  • increase scarring and infection
59
Q

Tertiary Intention

A
  • wound
  • granulation
  • closure with wide scar
  • delayed closure
  • increase scarring, may already have an infection that has to be cleared in order to heal
60
Q

62
Q

Used to close wound on parts of the body that do not experience tension or stretching

A

63
Q

Protocol for elastic wraps/bandages/stretch netting

A
