Question 5

Describe a typical wound healing timeline

Answer 5

Hemostasis: Starts at the onset of injury and is designed to stop bleeding. Blood vessels constrict to allow blood clotting. Platelets stick together to form a dam. Can take up to two days for larger wounds.

Inflammation: swelling is caused by blood vessels leaking transudate (salt, protein, water). Inflammation allows the wound to be cleaned. White blood cells destroy bacteria and remove debris. Can take up to a week.

Proliferation: The wound bed is filled with connective tissue that helps to create new blood vessels. Can take between 4 and 30 days.

Maturation: Scarring and thicker collagen forms. Can take up to a year.
