There are four stages for the healing of wound:-
1. Inflammatory phase: - This starts with the injury. Here, the blood vessels narrow, bleed, clot forms and several chemicals are released into the wound starting the healing process. Over several days, specialized cells clear the debris wound.
2. Proliferative phase: - In this phase, the latticework or matrix of cell begins to form in which new blood vessels and skins grow. It is these capillaries that give purple red or pink appearance to the wound.
3. Remodeling phase: - It starts after two or three weeks. The collagen becomes more organized and makes the tissue stronger. Over six months, it enhances in strength to reach 70 % of strength of uninjured skin.
4. Epithelialization: - In this process, a new skin is laid down which then becomes a barrier between body and outer environment. The primary purpose is to protect against loss of water and bacteria. Its reconstruction starts within few hours getting completed in 24 in sutured and clean wound. As inflammatory process gets prolonged, open wounds may take seven to ten days.
