Brief Summary
The purpose of this pilot interventional study is to collect preliminary data on administering packed red blood cell (PRBC) during cardiac arrest (CA). The primary objective is to assess the feasibility of PRBC transfusion during cardiac CA to help optimize the methods required to augment cerebral and other vital organ oxygen delivery during cardiopulmonary resuscitation (CPR). The secondary objectives are to assess the effect of PRBC transfusion during prolonged cardiac arrests on cerebral oxygenation, end tidal carbon dioxide (ETCO2), return of spontaneous circulation (ROSC), survival to discharge, biomarkers of neural injury and inflammation, and neurological outcomes at hospital discharge, 30 days post-CA, and 90 days post-CA.

Outcome Measures
Primary Outcomes (6)
Time (in mins) to administration of Packed Red Blood Cells (PRBC)
During Cardiopulmonary Resuscitation (CPR) (up to 20 minutes)
Frequency of antibody-mediated transfusion reactions
Outcome measure will be evaluated for the occurrence of intravascular and extravascular hemolytic reactions by measuring fibrinogen, D-dimer, platelet count, peripheral blood smear, and serum haptoglobin.
6-72 hours after Return of Spontaneous Circulation (ROSC)
Frequency of non-immune reactions
Non-immune reactions include Transfusion Associated Circulatory Overload (TACO) and Transfusion-Related Acute Lung Injury (TRALI) as determined by the Data Safety Monitoring Committee (DSMC).
6-72 hours after ROSC
Change in frequency of right ventricular (RV) dilatation
Baseline, up to 20 minutes post administration of PRBC
All-cause mortality
Mortality due to all causes
Up to 30 days after the last day of study participation
Proportion of patients with unfavorable neurological outcomes
The Cerebral Performance Category (CPC) score is a five-point scale used to assess neurological outcome after cardiac arrest and other events. Scores range from 1 to 5, a score of 1 or 2 is considered a favorable outcome, and scores of 3, 4, or 5 are considered an unfavorable outcome (severe neurological disability, persistent vegetative state or death).
Up to 30 days post-Cardiac Arrest (CA)
Secondary Outcomes (15)
Absolute change in peak regional oxygen saturation (rSO2)
2 minutes prior to administration, 5 minutes post administration of PRBC
Absolute change in mean rSO2
2 minutes prior to administration, 5 minutes post administration of PRBC
Relative change in peak rSO2
2 minutes prior to administration, 5 minutes post administration of PRBC
Relative change in mean rSO2
2 minutes prior to administration, 5 minutes post administration of PRBC
Relative change in peak end tidal carbon dioxide (ETCO2)
2 minutes prior to administration, 5 minutes post administration of PRBC
- +10 more secondary outcomes

Interventions
500 mL of packed red blood cells administered intravenously 10-20 minutes after CA onset, provided Return of Spontaneous Circulation (ROSC) has not been achieved.
1000 mL of packed red blood cells administered intravenously 10-20 minutes after CA onset, provided Return of Spontaneous Circulation (ROSC) has not been achieved.
Eligibility Criteria
You may qualify if:
- Adult patients, age ≥18 and \<85 years
- Experience prolonged, non-trauma-related in-hospital cardiac arrest, defined by cessation of heartbeat and respiration requiring CPR for at least 10 minutes
You may not qualify if:
- Age \<18 years old
- Age \> 85 years old
- Patients with DNR/DNI orders (Do Not Resuscitate/Do Not Intubate)
- Patients admitted to the hospital with a cardiac arrest arising from trauma
- Patients who achieve return of spontaneous circulation within 10 minutes of CPR
- Inability to start study product administration within 20 minutes of cardiac arrest onset
- Prisoners
- Women who are known to be pregnant
- Patients with a history of RBC antibodies or positive antibody screen prior to enrollment in the study, unless previously cross-matched units are available for transfusion.
- Patients with ultrasound evidence of right ventricular dilatation at time of CA
- Patients with known prior objection to receipt of blood products.
- Patients for whom administration of additional fluid volume is contraindicated (as determined by physician responsible for care)
- Physician objection based on concern that intervention would interfere with patient care plan
