Platelets collect & deposit fibrin to form a blood clot, vasoconstriction
Phase 2 Inflammation
Phagocystosis by white blood cells, scab formation
Phase 3 Proliferation
Primary intention wound develops new tissue (period of granulation) and collagen. The wound contracts with epithelialization. Secondary intention wound fills in with granulation tissue, followed by contractionand epithelialization.
Phase 4 Remodeling
Collagen becomes more elastic and stronger for the scar tissue
abnormal amount of collagen; hypertrophic scar
Collagen is formed into a scar, to increase the strength of the wound. Yet still only 80% as strong as the original tissue. Scar should become thinner & paler over time.
Clinical s/s of infection
Erythema, induration, pain fever, odor, color changes, purulent drainage
