Q

blood supply during the inflammation phase

A
  • vasodilation to bring in white blood cells to start cleaning it up
  • vasoconstriction after there’s enough there

Q

Which of the cardinal signs of inflammation does not always happen?

A

loss of function

may not happen depending on where the wound is, but the other four happen to some degree

Q

Why does the wound need to be moist?

Q

In addition to moisture, what does blood do for the wound?

A
  • brings nutrients to it

- brings substances to the wound site for proper healing

Q

purpose of proliferation

A
  • creation of new cells

- attempting to fill in the space

16
Q

How should a wound heal normally?

A

fills in bottom up and from the sides

17
Q

What do you never want to have happen in healing of a wound?

A

don’t want the sides to approximate before the basement rises

18
Q

What is the goal of wound healing?

A

want it to continue to grow to what the normal surface should look like?

19
Q

What area is susceptible to incomplete (abnormal?) wound healing?

A

skull: doesn’t fill into previous level

20
Q

What must happen during the proliferation phase in order for nutrients and moisture to continue to be brought to the wound?

A

angiogenesis

21
Q

Angiogenesis is essential to this process

A

re-epithelialization

22
Q

What is it called when the wound fills in?

A

epithelialization

23
Q

When does epithelialization stop?

A

when it reaches other epithelial cells

24
Q

epibole

A
  • epidermis keeps growing across and you get rolled edges on the wound
  • never grows across the wound
25
Q

When is it likely that an epibole will form?

A

with a wound that keeps opening up

26
Q

What is constantly being made during proliferation?

A

granulation tissue

  • think ground beef: red, moist
27
Q

What signifies the beginning of the maturation phase?

A
  • wound is no longer open to the outside environment

- there’s a scar

28
Q

How long does the maturation phase last?

A
  • can take anywhere from days to years

- depends on the size, area of skin, etc.

29
Q

What will you not get regrowth of if the wound is in the reticular region?

A

Won’t get sweat glands, sebaceous glands, hair follicles, lymphatics, or nerves

DO get angiogenesis

30
Q

scar colors: white people

A

red » pink » whitish

31
Q

scar colors: POC

A

deep purple » less purple » off normal skin color

32
Q

What may be killed off related to color?

A

melanocytes

33
Q

What is always true of scar tissue in comparison to normal tissue?

A
  • always different from normal skin
  • weaker tensile strength

(somewhere between 15-80%, never back as strong as it was before)

34
Q

At what point in the maturation phase is the scar weakest?

A

early on

35
Q

What does scar tissue increase the risk of?

A

higher risk of reinjury because it’s not as similar to normal anatomy

36
Q

What is the purpose of using cross-friction massage?

A
  • break down some of the excessive collagen

- hopefully replace with elastin

37
Q

Why is it so important to know your anatomy when dealing with wounds?

A
  • knowing whether or not to debride or leave it alone
  • everything filled in with scar tissue (ONLY filler)
  • a wound can hit ANYTHING it’s over
38
Q

What is autolytic debridement?

A

body cleans out the bad stuff and heals the wound on its own
