Background
Jehovah's Witness patients refuse allogenic blood and blood products. The major clinical complication due to their religious beliefs is life threatening bleeding. Multiple options exist to temporize and treat bleeding, which include:[1]
- Erythropoesis stimulation
- Iron supplementation
- Oxygen carriers
- Whole blood conservation
The use of advanced treatments are generally reserved for patients with severe anemia < 7g/dL
Control Bleeding
- Early surgical or hemostatic control
- Tranexamic Acid administration for major trauma < 3 hrs
- Prothrombin complex concentrates
- Recombinant factor VIIa
Erythropoesis Stimulation
High dose eppetin have a multimodal mechanism of action that includes an increase in reticulocyte count, decrease in plasma volume and increase in Hb levels[2]
Epoetin alfa (Epogen)
- Dose: 40,000 unites IV daily until Hb > 7g/dL then 40,000 units per week[3]
- Onset of Action: 3 days
- Patients must have sufficient iron supplementation or max erythropoesis will not occur
Iron Supplementation
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[4]
- IV iron sucrose 100 mg daily for 10 days[3]
- Oral Iron Supplementation afterwards
Vitamin Supplementation
Should be provided to all patients
- Vitamin C: 500 mg TID( q24hrs daily in renal failure)
- Folate: 1 mg PO or IV daily (q24hrs)
- Vitamin B12 multivitamin PO or IV
Decrease phelbotomy
- 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[5]
- Dosing: 1 unit (225 mL) administered IV over 4 hours if bleeding
- If patient develops hypertension slow infusion rate
