Study Notes
Blood Transfusion Basics
- Types of Blood Products: Packed red blood cells, platelets, fresh frozen plasma (FFP), cryoprecipitate, prothrombin complex concentrate (PCC)
- Transfusion Thresholds:
- Hemoglobin: < 7 g/dL for transfusion, < 8 g/dL for patients with pre-existing CAD/CHF/acute coronary syndrome.
- Platelets: < 50,000/µL for bleeding patients.
- PT/INR: > 1.6 for patients with coagulopathy.
- Fibrinogen: < 100-150 mg/dL for patients with hypofibrinogenemia
- Transfusion Risks:
- Packed red blood cells: Non-hemolytic transfusion reactions, alloimmunization, CMV infection, TRALI (transfusion-related acute lung injury)
- Platelets: Graft vs. host disease, allergic reactions
- Plasma Products: Allergic reactions (IgA deficiency, protein sensitivities), TACO (transfusion-associated circulatory overload)
- Massive Transfusion Protocol (MTP): Hypocalcemia, hypothermia, hyperkalemia, transfusion-associated circulatory overload (TACO)
Case Scenarios
Case 1: Anemia
- Patient: 55-year-old male with fatigue, lightheadedness, and shortness of breath on exertion, hemoglobin 6.8 g/dL.
- Treatment:
- Packed red blood cells to raise hemoglobin to > 7 g/dL.
- Lucco-reduction can reduce risk of CMV infection and non-hemolytic transfusion reactions in patients with frequent transfusions or immunocompromised status.
Case 2: Thrombocytopenia
- Patient: 45-year-old female with easy bruising and prolonged bleeding, platelet count 15,000/µL.
- Treatment:
- Platelet transfusion to raise platelet count to > 50,000/µL.
- Platelet washing can reduce risk of allergic reactions in patients with IgA deficiency or recurrent transfusion reactions.
- Avoid Platelet Transfusion:
- TTP (thrombotic thrombocytopenic purpura)
- HIT (heparin-induced thrombocytopenia)
Case 3: Coagulopathy
- Patient: 60-year-old male with epistaxis and generalized bruising, PT/INR 2.8, elevated PTT, liver cirrhosis.
- Treatment:
- FFP to replenish clotting factors and potentially lower INR to < 1.6.
- Thromboelastography (TEG) is a more accurate test for evaluating clotting function in cirrhotic patients.
- Vitamin K could be beneficial but less likely to be effective with liver cirrhosis.
Case 4: Warfarin Coagulopathy
- Patient: 70-year-old male with hematemesis and dizziness, PT/INR of 4.5, on warfarin for atrial fibrillation.
- Treatment:
- PCC (prothrombin complex concentrate) to rapidly replace vitamin K-dependent clotting factors (Factor 2, 7, 9, and 10).
- Vitamin K (10 mg IV) to stimulate the liver to produce clotting factors.
- Monitor INR and aim for < 2 in this case.
Case 5: DIC
- Patient: 40-year-old male with persistent bleeding from IV sites and worsening bruising, fibrinogen 80 mg/dL, platelet count 40,000/µL.
- Treatment:
- Cryoprecipitate is a highly concentrated source of fibrinogen, Von Willebrand factor, and Factors VIII and XIII, which are helpful for replacing fibrinogen and managing bleeding.
- Monitor fibrinogen levels and aim for a level > 150 mg/dL.
Case 6: TRALI
- Patient: 50-year-old female with shortness of breath and hypoxemia after receiving packed red blood cells, bilateral pulmonary infiltrates on chest x-ray.
- Diagnosis: TRALI (transfusion-related acute lung injury)
- Treatment:
- Stop the transfusion.
- Supportive care for respiratory distress, including oxygen, high-flow nasal cannula, BiPAP, or intubation.
Case 7: TACO
- Patient: 50-year-old female with pulmonary edema, JVD, and hypertension, after receiving 12 units of packed red blood cells, FFP, and platelets.
- Diagnosis: TACO (transfusion-associated circulatory overload)
- Treatment:
- Diuretics to remove excess fluid.
Case 8: Acute Hemolytic Transfusion Reaction
- Patient: Increased LDH, low haptoglobin, AKI, and hypotension after transfusion.
- Treatment:
- Stop the transfusion.
- Supportive care for hypotension.
Case 9: Massive Transfusion Protocol (MTP)
- Patient: Hypovolemic and bleeding from multiple sites after trauma.
- Treatment:
- MTP: 1 unit of packed red blood cells, 1 unit of FFP, and 1 unit of platelets, repeated as needed.
- Monitor: Blood pressure, calcium levels, potassium levels, temperature.
- Complications: Hypocalcemia, hypothermia, hyperkalemia, TACO
- Alternative ratio for MTP: 1 unit of packed red blood cells, 1 unit of FFP, 1 unit of platelets, 1 unit of cryoprecipitate - if fibrinogen is low.
Key Points
- Transfusion reactions are serious complications that can occur with any type of blood product.
- Early recognition and treatment are essential to prevent life-threatening consequences.
- It is important to understand the indications, risks, and complications of each blood product.
- Monitoring for potential complications is crucial, especially during massive transfusions.
- When in doubt, consult with a hematologist or other qualified healthcare professional.
