1.12 Wounds 1

Question 1

What are the phases of healing?

Answer 1

• inflammation
• proliferation
• maturation

Question 2

When does proliferation occur generally?

Answer 2

3-21 days

Question 3

How long does the inflammation phase last?

Answer 3

1-10 days

Question 4

blood supply during the inflammation phase

Answer 4

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

Question 5

function of platelets in inflammation

Answer 5

facilitate clotting

Question 6

cardinal signs of inflammation

Answer 6

• calor
• rubor
• dolor
• tumor
• loss of function

Question 7

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

Answer 7

loss of function

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

Question 8

Above all else, a wound need to be

Answer 8

moist

Question 9

Why does the wound need to be moist?

Answer 9

moisture is a direct correlation to proper blood flow

Question 10

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

Answer 10

• brings nutrients to it

- brings substances to the wound site for proper healing

Question 11

What are the 3 most important things in wound care?

Answer 11

• blood flow (moist)
• nutrients
• environment

Question 12

What are some environmental factors with wound healing?

Answer 12

• pressure (occlusion of blood flow)
• smoking
• living environment
• alcohol

Question 13

What does smoking increase? (vasoconstriction/vasodilation)

Answer 13

vasoconstriction

Question 14

hormonal consideration in inflammation phase

Answer 14

starting to get hormones to begin proliferation phase

Question 15

purpose of proliferation

Answer 15

• creation of new cells

- attempting to fill in the space

Question 16

How should a wound heal normally?

Answer 16

fills in bottom up and from the sides

Question 17

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

Answer 17

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

Question 18

What is the goal of wound healing?

Answer 18

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

Question 19

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

Answer 19

skull: doesn’t fill into previous level

Question 20

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

Answer 20

angiogenesis

Question 21

Angiogenesis is essential to this process

Answer 21

re-epithelialization

Question 22

What is it called when the wound fills in?

Answer 22

epithelialization

Question 23

When does epithelialization stop?

Answer 23

when it reaches other epithelial cells

Question 24

epibole

Answer 24

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

Question 25

When is it likely that an epibole will form?

Answer 25

with a wound that keeps opening up

Question 26

What is constantly being made during proliferation?

Answer 26

granulation tissue - think ground beef: red, moist

Question 27

What signifies the beginning of the maturation phase?

Answer 27

- wound is no longer open to the outside environment | - there's a scar

Question 28

How long does the maturation phase last?

Answer 28

- can take anywhere from days to years | - depends on the size, area of skin, etc.

Question 29

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

Answer 29

Won't get sweat glands, sebaceous glands, hair follicles, lymphatics, or nerves DO get angiogenesis

Question 30

scar colors: white people

Answer 30

red » pink » whitish

Question 31

scar colors: POC

Answer 31

deep purple » less purple » off normal skin color

Question 32

What may be killed off related to color?

Answer 32

melanocytes

Question 33

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

Answer 33

- always different from normal skin - weaker tensile strength (somewhere between 15-80%, never back as strong as it was before)

Question 34

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

Answer 34

early on

Question 35

What does scar tissue increase the risk of?

Answer 35

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

Question 36

What is the purpose of using cross-friction massage?

Answer 36

- break down some of the excessive collagen | - hopefully replace with elastin

Question 37

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

Answer 37

- 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

Question 38

What is autolytic debridement?

Answer 38

body cleans out the bad stuff and heals the wound on its own BEST way if at all possible
