Study Notes
Coagulation and Platelet Disorders Overview
- D dimer measures factors in clotting pathways, indicating high fibrin degradation products in the body
- PT and PTT interpretations for bleeding or clotting syndromes include examples of conditions associated with prolonged or normal results
- Vascular disorders such as purpura can be drug-induced, autoimmune, or related to connective tissue disorders
- Hereditary Hemorrhagic Telangiectasia presents as chronic dilation of capillaries, with localized red or purple lesions
- Thrombocytopenia's etiology includes decreased production, survival, pooling in the spleen, and dilution due to transfusions
- Thrombocytosis can be transient, secondary, or primary, leading to hemorrhage, occlusion of vessels, and tissue necrosis
- Qualitative platelet disorders include von Willebrand disease, Bernard-Soulier syndrome, and thrombasthenia, resulting in bleeding and increased bleeding time
- Hemophilia A and B are characterized by factor VIII and IX deficiencies, leading to bleeding, hemarthrosis, and joint deformities
- DIC involves widespread clotting and fibrinolysis, associated with snakebites, malignancy, transfusion reactions, and shock
- Measures and interpretations of PT, PTT, D dimer, and platelet counts are essential for diagnosing coagulation and platelet disorders
- Treatment options for these disorders include drug therapy, transfusions, injury prevention, and administration of deficient factors
- Understanding the etiology, symptoms, and treatment options for coagulation and platelet disorders is crucial for effective management and patient care
