Severe anemia in Jehovah's Witness patients
Jehovah's Witness patients traditionally refuse allogenic blood and blood products. The major clinical complication due to this is life threatening bleeding. Multiple options exist to temporize and treat bleeding, which include:
- Erythropoesis stimulation
- Iron supplementation
- Oxygen carriers
- Whole blood conservation
The use of advanced treatments are generally reserved for patients with severe anemia < 7g/dL
Individual Jehovah's Witnesses may not strictly adhere to this doctrine; up to 49% of Jehovah's Witness patients in one study would be willing to accept blood products in certain circumstances.  It's worth carefully discussing the risks/benefits with the patient (without visitors present), especially if the need is truly critical.
Early control of bleeding and coordination with the family or patient is the only means of managing an severely bleeding Jehovah's Witness patient. Most patients will accept autotransfusion.
- Early surgical or hemostatic control
- Tranexamic Acid administration for major trauma < 3 hrs
- Prothrombin complex concentrates
- Recombinant factor VIIa
- Autotransfusion (ie Cell Saver, CATS, or Fresenius cell salvage)
High dose epoetin have a multimodal mechanism of action that includes an increase in reticulocyte count, decrease in plasma volume and increase in Hb levels
Epoetin alfa (Epogen)
- Dose: 40,000 units IV daily until Hb > 7g/dL then 40,000 units per week
- Onset of Action: 3 days
- Patients must have sufficient iron supplementation or max erythropoesis will not occur
Supplementation will allow for full RBC production but will not correct anemia immediately. Most useful for preparing for scheduled surgical procedures or in burn patients
- Iron supplementation to keep serum iron 100-400mg/dl
- IV iron sucrose 100mg daily for 10 days
- For first dose, test dose 25 mg slow push over 15 min
- Wait 2 hrs, if no anaphylactoid reaction, give rest of 75 mg
- Oral Iron Supplementation afterwards
Should be provided to all patients
- Vitamin C: 500mg TID( q24hrs daily in renal failure)
- Folate: 1mg PO or IV daily (q24hrs)
- Vitamin B12 multivitamin PO or IV
- Use pediatric tubes for blood draws and limit daily volume to 1mL
Hb-based oxygen carriers (Hemapure)
Hemapure require individual patient IRB and institutional FDA approval and is experimental. Hemopure is approved in South Africa and Russia and is a purifiec acellular bovine Hb in lactated ringer's solution
- Dosing: 1 unit (225 mL) administered IV over 4 hours if bleeding
- If patient develops hypertension slow infusion rate
