|
Localized bleeding (cause)
|
injury in local area *surgical site, injury , infection, tumor
|
|
|
Generalized Bleeding (cause) |
Systemic throughout body, multiple sites, spontaneous and recurring that need intervention and transfusions. Primary Hemostasis: blood vessels, plts, Secondary Hemostasis: coag mechanism |
|
|
Acquired bleeding |
happens over time Take history--> CBC, plt count, pt, PTT FA. |
|
|
Congenital bleeding |
Born with. Uncommon 1 in 100 Most common is deficiencies in VWD, VIII, IX. |
|
|
Soft Tissue bleeding |
Generalized Acquired/Congenital Deficiency in coagulation factor bleeding may be: delayed, recurrent, spontaneous. internal in joints, cavities, muscles CNS Secondary hemostasis |
|
|
Mucocutaneous |
Generalized Primary Hemostasis Small bleeds: purpura, petechiae, ecchymoses Platelets! prolonged bleeding time nosebleeds, gums, menstrual flow, vomiting blood |
|
|
Trauma-Shock (ACOTS) |
Acquired Injury causes coagulopathy *Massive transfusion *Plt. decrease (mini vascular bleeds) Treat w/ FP, Plt (<50,000), Factor [ ] |
|
|
Liver Disease |
Localized/General; Mucocutaneous/tissue Decrease in Vit. K dependent factors and Protein C,S,Z. Factor V: APR, Fibrinogen VIII and XIII Decrease in plts. Hepatosplenomegaly
|
|
|
Liver Disease: Tests |
Fibrinogen: High than Low PT: prolonged PTT: depends on severity Hgb and Hem: Normal until bleeds Plt. could be decreased |
|
|
Vitamin K |
Nutritional: feeding tubes, biliary obstruction, fat malabsorption, Ab. Hemorrhagic Disease of Newborns Antagonists: Warfarin, rat poisons |
|
|
Vitamin K: Tests |
PT: prolonged PTT: pot. prolonged Mixing Study: correct w/ incubation 1 factor assays |
|
|
Von Willebrand Factor |
Made in endothelial cells and megakaryocytes Promotes plt adhesion Carries Factor VIII |
|
|
Clinical fetures |
Primary Hemostasis plts. Mucocutaneous bleeding. Dental, GI bleeding, leads to VIII deficiencies |
|
|
VWD Type 1 |
Quantitative deficiency 70-80% of cases |
|
|
VWD Type 2 |
Qualitative Disorders 20-30% |
|
|
VWD Type 2 A |
10-20% Proteolysis forms small multimers --> decrease in adhesion |
|
|
VWD Type 2 B |
<5% Binding to resting/normal plts. makes unavailable for adhesion. Thrombocytopenia |
|
|
VWD Type 2 M |
RARE Lap 1B cannot bind |
|
|
VWD Type 2 N |
Autosomal Hemophilia RARE impaired factor VIII binding site |
