Wound Healing

Question 1

First Intention/Primary Union

3 phases

Answer 1

Healing occurs from side to side in a sterile wound
Phase 1: Lag phase or Inflammatory Response Phase
Phase 2: Proliferation Phase
Phase 3: Maturation or Differentiation Phase

Question 2

Second Intention (Granulation)

Answer 2

Generally occurs in large wounds that cannot be approximated

wide irregulat scar may result in herniation

excessive granulation tissue is sometimes refferred as “proud flesh”

Question 3

Third Intention/ Delayed Primary Closure

Answer 3

a. traumatic surgical wound is deprided and purposely left open to heal by second intention for approximately 4-6 days.
b. the infection free wound is then closed and allowed to finish the healing process through primary closure.

a wound that heals by contraction, granulation, and connective tissue repair

Question 4

Complications….

Answer 4

Dehiscence (partial/total separation of tissue after closure)

Evisceration (protrusion of the viscera through edges of totally separated wound)

Hemorrhage (can result in postoperative shock)

Infection (microbial contamination)

Adhesion (abnormal attachment of two surfaces normally separate)

Herniation

Fistula (abnormal tract between to epithelium surfaces)

Question 5

Complications… Keloid scar

Answer 5

a hypertrophic scar formation, occurs in dark-skinned individuals

Question 6

Complications… Dead Space

Answer 6

separation of wound layers that have not been closely approximated
