|
|

|
|
Wound healing are recognized by three mechanism, in which they are
|
First intention or primary
Second intention Third intention or delayed primary closure |
|
|
Occur w/ primarily union that is typically of an incision opened under ideal conditions, healing occur from side - to - side in the sterile wound in which dead space has been eliminated
|
First intension or primary union
|
|
|
Healing by first intension occurs in three distinctive phase
Phase 1 - Lag phase or inflammatory response |
Stage begins within minutes of injury and last approximately 3 - 5 days, inflammatory process occur, a scar forms on the surface to seal the wound leukocytes move to the endothelial lines and basal cell migrate across the skin edges, the wound does not gain tensile during this phase
|
|
|
Phase 2
- Proliferation phase |
Begins approximately the third postop day and continue for up to 20 days, fibroblast secrets collagens, new network from existing capillaries are established by the 5th to 8th days, lymphatic network are reformed by the 10th day.
|
|
|
Phase 3
- Maturation or differentiation phase |
Begins on 14th postop day and last until the wound is completely healed (up to 12 months), wound contraction is the result from the work of dermal and subcutaneous myofibroblast is completed in approximately 21 days, small white mature surface scar called cicatrix appear during this phase.
|
|
|
Key words:
a) Normal scar formation (expected) b) Raised, thickened scar due to excessive collage formation |
a) Cicatrix
b) Keloid |
|
|
c) Excessive granulation issue
d) Ability to resist rupture |

d) Tensile strength |
|
|
Occurs when the wound falls to heal by primary union, generally occurs in large wound that cannot directly be approximated or in which infection has caused breakdown in suture
|
Second intention - Granulation
|
|
|
TO KNOW:
- Second intention healing may be allowed following to removal of necrotic tissue or after a wide debridement, the wound is left open and allowed to heal from inner layer to the outside surface. |
- Is more complicated and prolonged process.
- Granulation tissue that contains myofibroblast forms in the wound causing closure by contraction. |
|
|
- As a wound heals large gaps in tissue fill from the bottom upward with granulation tissue leaving a weak union and a wide and irregular scar resulting in herniation.
|
- Excessive granulation tissue may protrude above the defect margins and block re - epithelialization.
|
|
|
Healing or delayed primary closure, occur when two granulated surface are approximated, the traumatic surgical wound is debrided and purposed left open to heal from secondary intention for approximately 4 to 6 days.
|
Third intention - Delayed primary closure
|
|
|
