(2) inflammatory, Fibroblasts begin secreting appreciable collagen. (3) proliferative and Collagen deposition is important because it (4) remodeling increases the strength of the wound; before it is laid down. Formation of granulation tissue in an open woundA. Homostasis allows the reepithelialization phase to take place, as epithelial cells migrate across the new tissue to form Within minutes post-injury, platelets (thrombocytes) a barrier between the wound and the environment aggregate at the injury site to form a fibrin clot. This clot acts to control active bleeding D. Remodeling Phase (hemostasis) When the levels of collagen production andB. Inflammatory Phase degradation equalize, the maturation phase of tissue repair is said to have begun. The maturation phase can last for a year or longer, When tissue is first wounded, blood comes in depending on the size of the wound and whether it contact with collagen, triggering blood platelets to was initially closed or left open. begin secreting inflammatory factors. During Maturation, type III collagen, which is Platelets, release a number of things into the blood, prevalent during proliferation, is gradually degraded including ECM proteins and cytokines, including and the stronger type I collagen is laid down in its growth factors.Growth factors stimulate cells to place speed their rate of division. Platelets also release other proinflammatory factors like serotonin, bradykinin, prostaglandins, prostacyclins, thromboxane, and histamine, which Primary Intention: cause blood vessels to become dilated and porous. The main factor involved in causing vasodilation is When wound edges are directly next to one another histamine. Histamine also causes blood vessels to: Increased Capillary Permeability causes hyperemia Little tissue loss that leads to redness (rubor) and presence of heat Minimal scarring occurs (calor) and Most surgical wounds heal by first intention healing Fluid and cellular exudation that causes edemaand Wound closure is performed with sutures, staples, presence of exudates or adhesive at the time of initial evaluation Within an hour of wounding, polymorphonuclear neutrophils (PMNs) arrive at the wound site and Secondary Intention: become the predominant cells in the wound for the first two days after the injury occurs.They also cleanse the wound by secreting proteases that break The wound is allowed to granulate down damaged tissue. Surgeon may pack the wound with a gauze or use a Neutrophils usually undergo apoptosis once they drainage system have completed their tasks and are engulfed and Granulation results in a broader scar degraded by macrophages Healing process can be slow due to presence of The macrophages main role is to phagocytise drainage from infection bacteria and damaged tissue and it also debrides damaged tissue by releasing proteases. Wound care must be performed daily to encourage Macrophages also secrete a number of factors such wound debris removal to allow for granulation tissue formation as growth factors and other cytokines, especially during the third and fourth post-wounding days. These factors attract cells involved in the Tertiary Intention (Delayed primary closure): proliferation stage of healing to the area
