Title: Aneurysmal Subarachnoid Hemorrhage - Red Blood Cell Transfusion and Outcome (SAHaRA): A Randomized Controlled Trial
Brief Summary: The SAHaRA trial will clarify the role of treating anemia with Red Blood Cell (RBC) transfusion in a unique and vulnerable patient population, and determine whether that impacts on functional outcomes and mortality. It will guide best practice standards and clarify the optimal RBC transfusion strategy in patients with aSAH.

A: Inclusion Criteria:

* Women older than 18 years
* 12-24 hours after delivery (vaginal or caesarean section)
* Patients are in a clinical obstetric setting
* Blood loss of more than 1000 mL or Hb decrease ≥ 1,9 g/dL
* Hb value between 4.8 g/dL and 7.9 g/dL
* Working knowledge of the national language
* Written consent for participating this study (informed consent)

Exclusion Criteria:

* Patients with severe preeclampsia/ HELLP syndrome
* RBC transfusion during or after delivery but before t=0
* Patients with malignancy
* Patients with severe congenital haemolytic disease, like thalassemia or sickle cell disease
* Patients with compromised immunological status, congenital or acquired by medical treatment or infectious disease (eg. HIV)
* Severe active infectious disease at the time of proposed inclusion
* Severe cardiac, pulmonary, neurological, metabolic or psychiatric co- morbidity (ASA II/III) at the time of proposed inclusion
* Severe physical complaints (tachycardia of more than 100 bpm, dyspnoea, syncope, heart problems) at the time of intended inclusion
* Peripartum death of the newborn, or the newborn being in critical condition on neonatal intensive care
B: Inclusion Criteria:

1. Age ≥18 years old at time of SAH
2. First ever episode of aneurysmal SAH
3. Diagnosis of aSAH as confirmed by treating physician (eg: neurosurgeon or neuro- interventionalist) and supported by blood in subarachnoid space (e.g. cranial imaging or cerebrospinal fluid positive for xanthochromia, surgical visualization) that is the result of a ruptured aneurysm (e.g. direct visualization, cranial imaging or catheter angiogram)
4. Hb ≤100g/L within 10 days following aSAH (defined by first day of hospital presentation)

Exclusion Criteria:

1. Physician and or family decision to withdraw/withhold active medical care at time of enrolment
2. Active bleeding with hemodynamic instability at time of enrolment
3. Patients with contraindication or known objection to blood transfusions
4. SAH due to mycotic aneurysm, infundibulum and vascular malformations.
C: Inclusion Criteria:

All of the following must be present:

* Acute myocardial infarction with presentation within 72 hours of randomization (acute myocardial infarction is defined as ischemic-type chest discomfort lasting at least 30 minutes associated with creatinine kinase MB (CKMB) or troponin \>upper limit of normal \[ULN\])
* Admission to CCU
* Hematocrit .30 or less
* Written, informed consent

Exclusion Criteria:

* Inability or unwillingness to receive red cell transfusions
* Active bleeding (overt blood loss accompanied by a decrease in hematocrit of at least 5% in the preceding 12 hours)
* Receipt of red cell transfusion within 7 days of randomization
* Prior severe transfusion reaction
* Pregnancy
* Imminent death
* Decision to provide limited care
* Age \<21
* Participation in another clinical trial in which blood transfusion is a requirement or a component of a primary or secondary endpoint
* Previous participation in the CRIT Pilot
D: Inclusion Criteria:

* Women over 18
* Willing and stable to give consent
* \> 6 hours postpartum from any mode of delivery
* Determined by their physician to require blood transfusion either by:

  * Hb \<7g/dL OR
  * \>7g/dL with any sign or symptom of anemia such as fatigue, dizziness, tachycardia, or hypotension
* Agreed to accept blood transfusion
* No contraindications to blood transfusion

Exclusion Criteria:

* hemoglobinopathies
* patients with an ejection fraction \<35%
* Hb \<5 g/dL
* HR \> 130 bpm, BP \< 80/40
