Inflammation, Wounds, and Pressure Ulcers part 4

Question 1

Wound Healing Primary Intention:

When does primary intention healing take place? And what are the edges closed by?

Answer 1

• when wound margins are neatly approximated
• closed by stitches, staples, skin glue
• EX: surgical incision

Question 2

Wound Healing Primary Intention:

What are the 3 phases?

Answer 2

initial
granulation
maturation

Question 3

Wound Healing Primary Intention:

Approximation of incision edges. Migration of epithelial cells. Clot serving as meshwork for starting capillary growth

Answer 3

Initial (inflammatory) 3 to 5 days

Question 4

Wound Healing Primary Intention:

Migration of fibroblasts. Secretion of collagen. Abundance of capillary buds. Wound fragile

Answer 4

granulation 5 days to 4 weeks

Question 5

Wound Healing Primary Intention:

Remodeling of collagen. Strengthening of scar

Answer 5

Maturation 7 days to several months

Question 6

Wound Healing: Secondary Intention

What are some examples and edge types?

Answer 6

• EX: burns, major trauma, pressure injury
• Wounds that occur from trauma, injury, and infection have large amounts of exudate and wide, irregular wound margins with extensive tissue loss.
• large amount of tissue loss, edges may not be approximated

Question 7

edges not approximated

Answer 7

Wound Healing: Secondary intention

Question 8

More cellular debris, cells, and exudate
Debris removed from wound
Greater gaping wound edges larger scar
Granulation–> edges inward and from the bottom upward

Answer 8

Wound Healing: Secondary Intention

Question 9

Delayed closure due to infection

Answer 9

Wound healing: tertiary intention

Question 10

When does a tertiary intention occur?

Answer 10

• contaminated wound is left open and sutured closed after the infection is controlled
• primary wound becomes infected, is opened, allowed to granulate, and then sutured.

Question 11

What type of scar results from tertiary intention

Answer 11

Tertiary intention usually results in a larger and deeper scar than primary or secondary intention.
