WOUND MANAGEMENT
ACUTE WOUND –
ACUTE WOUND is a surgical wound that heals by the primary
intention or any traumatic or surgical wound that heals by
secondary intention
...
This pathological inflammation is due to a postponed , incomplete
or uncoordinated healing process
...
TYPES
Primary intention The wound edges are held together by artificial means such as
sutures , staples tapes or tissues
...
Delayed primary intention –
When the wound is infected or requires more through intensive
cleaning or debridement prior to primary closure usually 3-7 days
later
...
Secondary intention –
spontaneous wound healing occurs through a process of
granulation , contraction and epithelialization
...
skin graft –
removal or partial or full thickness segment of epidermis and dermis
from its blood supply and transplanting it to another site to speed up
healing and reduce the infection
...
flaps are named according to their tissue components and
may include as anastomosis of blood supply to vessels attached to
or at the affected site
...
it involves the following components :1) Vasoconstriction
2) Platelet response
3) Biochemical response
TISSUE REPAIR AND REGENERATION –
Tissue repair and regeneration involve 3 phases
1) Inflammation phase ( 0-4 days )The body normal response to injury this phase activates
vasodilation leading to increased blood flow causing heat
...
2) Reconstriction phase (2-24 days )The time when the wound is healing
...
this
phase includes reconstruction and epithelialization
...
3) Maturation phase (24 days – 1 year ) –
The final phase of healing
...
the
wound is still at a risk
Wound bed clinical appearance
1)granulating –
When a healthy red tissue is observed and is deposited
during the repair process
...
this tissue is well
vascularized and bleed easily
...
The tissue is pink , almost white and only occurs on the top
of healthy granulation tissue
...
Must not be
confused with the presence of pus
...
the
wound may appear hard , dry and black
...
the presence of dead tissue in a
wound presents healing
...
this occurs when the
proliferative phase of healing is prolonged usually as a
result of bacterial inbalance or irritant forces
...
raised or rolled edges raised ( where the
wound margin is elevated above the surrounding tissue)
May indicate hyper granulation tissue and rolled where
the edges are rolled down towards the wound bed can
inhibit healing
