At times, however, where generalized oozing is present and the use of pressure is not effective, and the use of electrosurgical instruments could endanger teeth or nerves, topical hemostatic agents may be needed. The second step is a mechanical blockage of the defect by a plug that forms as platelets stick to the exposed collagen (platelet adhesion) and become activated, releasing cytokines (serotonin, thromboxane A2, and endothelin1) into the area around the injury.

An infant with a total blood volume of 800 mL would start showing signs of shock when as little as _____ of blood is lost. At the same time, exposed collagen and tissue factor initiate the third step, a series of reactions known as the coagulation cascade that ends in the formation of fibrin polymer. Some of the newer agents that are available to the dental profession have been presented. The extrinsic pathway is stimulated by tissue factor, which is exposed by the tissue injury and through factor 7 activation initiates this pathway.
