|
|
|

|
|
|
476. Rh HDN
|
mother Rh negative and baby Rh positive; first pregnancy with Rh + baby has no effect on baby but mother could be exposed to fetal RBCs with D antigen during delivery and develop antibodies (purpose of Rh immune globulin is to prevent this); if subsequent pregnancies have Rh + babies, maternal anti-D IgG antibodies cross placenta -~ attach to fetal RBCs -, RBCs extravascularly removed by fetal macrophages in the spleen —‘ unconjugated bilirubin (UCB) is end-product of hemolysis —, fetus develops anemia (chance of heart failure and hydrops fetalis) and mother’s liver takes care of the UCB —, bilirubin pigment can be detected in amniotic fluid (optical wavelength of 450) and mapped on a Liley graph to determine severity of hemolysis -+ at delivery, baby cannot handle UCB load and is often exchange transfused to prevent kernicterus, remove UCB, remove antibodies, correct anemia

|
|
|
480. Factors preventing small vessel bleeding
|
heparin (enhances antithrombin III [ATm], which neutralizes most serine protease coagulation factors-prothrombin, X, DC~ XIL Xl, thrombin), P012 (synthesized by endothelial cells, vasodilator, inhibits platelet aggregation), protein C and S (inactivate factors V and VIII, enhance fibrinolysis), tissue plasminogen activator (release of plasmin, which destroys coagulation factors and clots)
|
|
|
481. Factors acting as procoagulants in small vessel injury
|
thromboxane A2 (synthesized by platelets, vasoconstrictor, enhances platelet aggregation; cyclooxygenase blocked by aspirin and NSA.1DS), von Willebrand factor (Vffl VWF; synthesized by endothelial cells and megakaryocytes, platelet adhesion factor [platelets have receptors for VIIl VWF]), extrinsic and intrinsic coagulation system B44
|
|
|
482. Normal events with vessel injury
|
vessel injury —~ activation of factor VII in the extrinsic coagulation system by tissue thromboplastin and activation of factor XII in the intrinsic system by exposed collagen —4 platelets stick to VIIJ VWF via their receptors (platelet adhesion) - stimulus for platelet release of AD? from dense bodies causing platelet aggregation and synthesis of TXA2 - temporary platelet plug with fibrinogen draped over it (fibrinogen flbrinogen into flbrin and forms a stable platelet plug -+ plasmin destroys the plug and reestablithes blood flow
|
|
|
483. Bleeding time
|
detects platelet abnormalities up to the formation of the temporary hemostatic plug (thrombocytopenia; no VflI VWF for platelet adhesion; patient on aspirin and no TXA2 for aggregation [most common cause])
|
|
|
484. Ristocetin cofactor assay
|
best test for Vffl VWF (von Willebrand factor, which is synthesized by endothelial cells and megakaryocytes and is necessary for platelet adhesion [platelets have receptors])
|
|
|
485. Prothrombin time (Fl)
|
detects extrinsic coagulation system factors down to formation of a clot—VU (extrinsic system) -~ X —~ V -4 U (prothrombin) -, I (fibrinogen) -+ clot; international normalized ratio (for patients on warfarin) standardizes the test throughout the world so all test results are the same regardless of the reagent used; PT is best test for liver synthetic function
|
|
|
486. Partial thromboplastin time (PTT)
|
detects intrinsic coagulation system factors (XII, XI, IX, Viii) down to formation of aclot-XU -, XI -4 IX -4 VIII -4 X .4 V —311 (prothrombin) - I (flbrinogen) —4 clot; used to follow heparin therapy and factor deficiencies
|
|
|
487. Factor VU deficiency
|
prolonged PT and normal PU
|
|
|
488. Factor VIII deficiency (hemophilia A
|
decreased VUI coagulant, normal VIII antigen and Vffl VWF) normal PT and prolonged PU
|
|
|
489. Factor X deficiency
|
prolonged PT and PiT
|
|
|
490. Patient on heparin
|
prolonged PT and PTT but PU is the better test to follow patients; if ovcranticoagulatcd give protamine sulfate
|
|
|
491. Patient on warfarin (blocks vitamin Ks ability to y-carboxylate factors U, VU, IX, X, protein C and S by blocking epoxide reductase, which normally keeps vitamin K in its active KI state)
|
prolonged PT and PU but PT is better test for following patients; if overanticoagulated and seriously bleeding give fresh frozen plasma and IM vitamin K; if bleeding not serious, give TM vitamin K
|
|
|
492. Patient with VWD (all factor VIII components decreased
|
VIII coagulant, Vffl normal PT and prolonged PU autigen, Vffl VWF) prolonged bleeding time, normal PT, prolonged PT!’
|
|
|
493. Patient with antibody against factor Vui
|
coagulant (circulating anticoagulant, inhibitor) and prolonged PTT normal PT and prolonged PTT; after mixing 0.5 cc of normal plasma with 0.5 cc of patient plasma, the Pfl is repeated and is still prolonged because antibodies inhibited VIII coagulant in the normal plasma as well; a true factor ViiLcoagulant deficiency would have correction of the PIT after adding normal plasma
|
|
|
494. Fibrinolytic system tests
|
fibrin (ogen) split.products (X, Y, D, E fragments) after plasmin breakdown of fibrinogen or a fibrin clot; D-dimers, which measures cross-linked fibrin monomers in a fibrin clot

|
intravascular consumption of clotting factors (fibrinogen, V, VIII, prothrombin, platelets) with diffuse, oozing of blood from all breaks in the skin; causes . endotoxic shock, infections, snake envenornation, amniotic fluid embolism); prolonged PT and PU, low fibrinogen, increased split products and. D-dimer (these are the best tests for DIC), thrombocytopenia, schistocytes (RBCs hit fibrin clots); treat the underlying disease causing DIC; use blood components to keep the patient alive; heparin blocks thrombin, hence preventing clots and consumption of coagulation factors B161
|
|
|
496. Hereditary thrombosis syndromes
|
venous thrombosis and pulmonary emboli; ATIII deficiency (no prolongation of PIT after starting heparin), protein C and S deficiency
|
|
|
497. Heparin
|
prevents venous clot formation; does not dissolve the clot; can be used in pregnancy; can produce thrombocytopenia
|
|
|
498. Warfarin
|
blocks epoxide reductase (normally keeps vitamin K in its active K! state); previously y-carboxylatcd vitamin K dependent factors must disappear before patient is fully anticoagulated (reason why heparin is given along with warfarin); VII and protein C have the shortest half-life (6 hours) and prothrombin the Longest (3 days);. hemorrhagic skin necrosis patient with heterozygote protein C deficiency and 50% factor level, when put on warfarin will have 0% protein C levels in 6 hours causing thrombosis of vessels in the skin before the patient is fully anticoagulated B174
