Acute wound results from loss of anatomic tissue structure due to transfer of
-kinetic
-chemical
-thermal energy
(cut, blow, burn, pressure, other impact)
When a wound occurs there is a breakdown in skin due to:
loss of continuity of epithelium
Most surgical wounds are ACUTE, and wound healing is normally completed in:
6-12 weeks
(some tissues heal more quickly than others)
