(Age of incised wound- Fresh- Haematoma formation, 12 hours- Edges are red, swollen, adherent with blood and lymph, 24 hours- A continuous layer of endothelial cells cover the surface, scabbing seen, 36 hours-The capillary network is complete, 48 to 72 hours- The wound is filled with fibroblasts, 3 to 5 days- Definite fibrils running parallel to the vessels are seen; vessels show thickening and obliteration, 1 to 2 week - Scar tissue is formed.)
Age of the bruiseQ is calculated as →
1. At first : Red
2. Few hrs to 3 days: Blue
3. 4th day : Bluish- black to brown (hemosiderin)
4. 5 – 6 days : Greenish (Haematoidin) - HEMATOIDIN PIGMENT
5. 7 - 12 days : Yellow (Bilirubin)
6. 2 weeks : Normal skin colour.
(Normally, pus formation occurs in about 48 hours, but in a lacerated wound it occurs slightly earlier.)
