The three intentions of wound healing are first intention, second intention and third intention. The first intention is what most OR cases expect and want because it is primary healing without infection, this intention has three phases. The first phase is the inflammation phase, which takes about 1-5 days, during this time clots form and macrophages and fibroblasts arrive. The second phase is the proliferation phase, which takes about 4-14 days and the sutures are removed, during this collagen is secreted and new capillaries grow in. The third phase is the maturation phase, which takes about 12-90 days, during this collagen matures and the scar forms with time the scar gains about 70-80% more strength. The second intention is wound infection
