Sents a really serious risk when the capacity to handle bleeding is diminished by alteration in some phase of hemostasis, either congenitally or acquired. These patients may have bleeding gums, characterized by becoming much more persistent than far more intense, so the volume of blood loss could be considerable. This truth is very important for the reason that mild or minimal trauma, like those ones that could happen consuming or brushing your teeth, might be adequate to result in gingival bleeding in these individuals (1). It can be therefore important that the stomatologist effectively recognize and determine individuals at risk of bleeding during dental therapy to stop or decide what measures to take for bleeding. Within the hemostasis approach are distinctive stages and phases, which involved unique cell lines and various proteins (soluble in idle status) of blood. The final result will be the formation of a red/fibrin mesh (insoluble protein in the blood) inside it encompassed blood cells (platelets, erythrocytes) are discovered. This grid/mesh acts as a barrier and prevents the loss of blood vessel injury by till the vascular tree is repaired. Before vascular injury in hemostasis, will create two successive stages, with major and secondary hemostasis three phases: a) vascular phase b) platelet phase c) plasma phase with plasma proteins involved in coagulation and clot removal later by fibrinolysis.I RevisionI) Primary Hemostasis It is the primary hemostatic plug formation. Depends upon the vascular integrity (endothelium and subendothelium), and platelet function (quantitative and qualitative). During this stage two mechanisms are involved: a single vessel and another platelet. A) Vascular spasm.: This vasoconstrictor response serves two purposes: it reduces blood loss, because of the closure with the injured vessel, and starts the second phase, facilitating platelet adhesion, by a change within the electric charge and exposure from the collagen fibers in the injured vascular wall (2), aided by quite a few substances and structures that exist in the vascular endothelium (PGI2, ADP-asa, thrombomodulin, tissue Activators Plasminogen and von PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20361986 Willebrand aspect, fibronectin, collagen fibers and proteoglycans, etc). B) Platelet Activation. Platelets are cell fragments, without nucleic acids inside, on the megakaryocytes (three).eInside are two forms of granules: a) granules, round and ovoid. Containing hydrolytic enzymes, fibrinogen, platelet aspect four, clotting aspects, trombostenina and also other compounds b) dense granules containing serotonin, ADP, ATP, calcium, potassium, thromboxane A2 and substances involved in hemostasis. Platelet membrane is formed by a phospholipid-protein trilaminar membrane, whose inner component filaments communicate with all the surface. On the surface from the membrane, appear several glycoproteins which can be important for platelet adhesion and aggregation. Within the platelet plug formation are two stages: Firstly apposition and platelet adhesion and buy GSK2837808A secondly platelet aggregation and secretion (4-6). II) Secondary Hemostasis It really is named plasma phase, covering the phenomena of coagulation and fibrinolysis. Not too long ago, it has been proposed a new model in clotting, which describes three phases (initiation phase, amplification phase and propagation phase). In this new model are offered novel ideas as “The Tisular complicated factor-F VII” that participates within the activation of factor IX, what implies that the intrinsic and extrinsic strategies are linked practically in the beginning from the course of action as well as, the complete method.
