- 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.

Group Intervention Description Saline solution Saline Treatment of 500 mL of normal saline. Packed Red Blood Cells (1 unit) Packed Red Blood Cells (1 unit) 500 mL of packed red blood cells Packed Red Blood Cells (2 units) Packed Red Blood Cells (2 units) 1000 mL of packed red blood cells
- Primary Outcome Measures
Name Time Method Time (in mins) to administration of Packed Red Blood Cells (PRBC) During Cardiopulmonary Resuscitation (CPR) (up to 20 minutes) Change in frequency of right ventricular (RV) dilatation Baseline, up to 20 minutes post administration of PRBC Proportion of patients with unfavorable neurological outcomes Up to 30 days post-Cardiac Arrest (CA) 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).
Frequency of antibody-mediated transfusion reactions 6-72 hours after Return of Spontaneous Circulation (ROSC) 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.
Frequency of non-immune reactions 6-72 hours after ROSC 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).
All-cause mortality Up to 30 days after the last day of study participation Mortality due to all causes
- Secondary Outcome Measures
Name Time Method 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 Rate of survival 90 days post-CA Relative change in peak end tidal carbon dioxide (ETCO2) 2 minutes prior to administration, 5 minutes post administration of PRBC CPC score 90 days post-CA 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).
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 mean ETCO2 2 minutes prior to administration, 5 minutes post administration of PRBC Proportion of patients with release of pro-inflammatory cytokines 6-72 hours after ROSC Proportion of patients with release markers of brain injury 6-72 hours after ROSC Rate of ROSC During CPR (up to 20 minutes)
