  Briefly write somethingabout the hospital. This will give the audience a better understanding about what you are trying to say. Why Choose Us? 24/7 Stages Hemostasis Inflammation Proliferation Remodeling Explanation Clot formation Inflammatory and growth factor release The body make new skin tissue and repair broken blood vessels The wound fully closes and the cells used for repair are no longer necessary Duration Immediately after injury 1 - 4 days 4 - 21 days Several months last up to year

  ●Healing phases 1. Hemostasisphase (1st phase) > Time : Begins immediately after injury. • Lasts minutes to hours. > Aim: Stop Bleeding. So, the main purpose is to stop bleeding and form a clot.
• 8.
  • What happensin hemostasis? > Blood vessels shrink [ vasoconstriction ] to slow down bleeding. > Platelets (tiny blood cells) rush to the cut and stick to the wound. And forms a plug (clot) to stop bleeding. > Special proteins [like Fibrin] make a strong mesh [NET] Over the wound. And releases growth factors to call other healing cells [Fibroblast]
• 9.
  Inflammation phase 2. > Itis the 2nd phase of healing. > Time : Starts in few hours, Lasts upto 1 to 4 days. > Aim : To clean the wound, protect it from infection and prepare it for repairing.
• 10.
  Why Choose Us? •What happens in inflammatory phase? > Vasodilation : Blood vessels opens up, So more blood and cells can come in. > Injured area becomes red, warm, swollen and painful. > WBC [ White Blood Cells ] like Neutrophils and Macrophage arrive. > They kill bacteria and remove dead cells. > Macrophages also release signals to begin tissue repair.

  Larana Inc. 3. Proliferationphase > It is the 3rd phase of healing. > Time : 4th to 21st day after injury. > Aim : To rebuild and cover the wound by forming new tissue blood vessels and skin.
• 12.
  • What happensin proliferation phase? > Angiogenesis [Formation of new blood vessels]. > Fibroblasts activation and collagen production. > Skin repair. > Formation of granulation tissue.
• 13.
  4. Remodeling Phase >It is the 4th and final stage of healing. > Remodeling stage also known as Maturation phase. > Time: Lasts several months upto 1 year. > Aim: To strengthen the body part after it is repaired or healed.
• 14.
  • What happensin remodeling phase? > Collagen replacement and organization. > Tensile strength gains. > Removal of excess cell and vessels. > Scar maturation.

  • Uses ofultrasound in 4 stages. > Hemostasis -Ultrasound is not used to maintain homeostasis because it can disrupt cellular processes and potentially cause harm, rather than maintain a stable internal environment. > Inflammatory phase. - Accelerate the healing process by stimulating mast cell degranulation which releases histamine and other mediators that attract immune cells to the injury site.

  > Proliferation phase -Promotes fibroblasts migration and collagen production crucial for tissue repair. > Remodeling phase - Improve tissue strength and flexibility by affecting collagen extensibility and enzyme activity.
