Title: Effects of Erythropoietin on Cerebral Vascular Dysfunction and Anemia in Traumatic Brain Injury
Brief Summary: The purpose of this study is to determine the effect of early administration of recombinant human erythropoietin on long-term neurological outcome after severe traumatic brain injury.


Options:
A: Inclusion Criteria:

* \>= 12 years old
* \>= 40 kg body weight
* Scheduled complex cardiac surgery with planned use of median sternotomy.
* Patients ≥ 18 years must have a Transfusion Risk Understanding Scoring Tool (TRUST) probability score ≥ 3

Exclusion Criteria:

* Refusal of blood products
* Planned surgery is minimally invasive
* Known transfusion reaction history
* Requirement for washed products, volume reduced products, or products with additive solution removed

* Left ventricular assist device (LVAD) or Extracorporeal membrane oxygenation (ECMO) support pre-operatively or planned need post-operatively
* Cardiogenic shock requiring pre-operative placement of an Intra-aortic balloon pump (IABP) (IABP done for unstable angina or prophylactically for low ejection fraction is not excluded)
* Planned Deep Hypothermic Circulatory Arrest (DHCA)
* Renal dysfunction requiring pre-operative renal replacement therapies such as hemodialysis (HD) or continuous venovenous hemofiltration (CVVH)
* Planned use of alternative to heparin, e.g. bivalirudin
* Planned use of autologous or directed donations
* Prior RBC transfusion during hospitalization for the study-qualifying surgery
* Prior randomization into the RECESS study
B: Inclusion Criteria:

* Blunt trauma mechanism of brain injury
* Glasgow Coma Score - motor component ≤ 5 (not following commands) on the post-resuscitation neurologic exam
* Available for enrollment and administration of study drug within 6 hours of injury

Exclusion Criteria:

* Penetrating trauma (i.e. gun shot wounds)
* Glasgow Coma Score = 3 and bilateral fixed and dilated pupils
* Abbreviated Injury Scale score \> 5 for any body part except brain
* Severe pre-existing chronic disease
* Uncontrolled hypertension, defined as mean arterial pressure \> 130mmHg despite antihypertensive treatment
* Known hypersensitivity to mammalian cell-derived products or human albumin
* Currently taking anticoagulants
C: Inclusion Criteria:

* 18 years or older
* Patients undergoing replacement of hip arthroplasty

D: Inclusion Criteria:

* Has undergone surgical repair for a hip fracture
* Has a postoperative Hgb level below 10 g/dL within three days of surgery
* Diagnosis of cardiovascular disease (e.g., coronary artery disease, congestive heart failure, stroke or transient ischemic attack, or peripheral vascular disease) or cardiovascular risk factors (e.g., diabetes mellitus, hypertension, hypercholesterolemia, tobacco use, or creatinine levels greater than 2.0 mg/dL)

Exclusion Criteria:

* Unable to walk prior to hip fracture
* Declines blood transfusions
* Suffered multiple traumas
* Pathologic fracture of the hip due to malignancy
* Clinically recognized acute myocardial infarction within the 30 days prior to study entry
* Previously participated in the trial and fractured the other hip
* Symptoms associated with anemia (e.g., ischemic chest pain) or actively bleeding at the time of randomization
