- Allocation: RandomizedIntervention Model: Parallel AssignmentMasking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)Masking Description: A randomization list was prepared by an independent statistician using 1:1 randomization in blocks of four. This list will be provided to the research pharmacy, and the research pharmacy will be the only unblinded people involved with the study, and will have no patient contact or role in the analysis or other aspects of the study. Thiamine is colorless and odorless, and the 500mg dose is mixed in 100mL of normal saline. Placebo will be 100mL of normal saline and is indistinguishable in appearance from thiamine. Study team, clinical team and patient and family will all be blind to the allocation.Primary Purpose: Treatment
Participation Requirements
- Age
- Between 18 years and 125 years
- Gender
- Both males and females

This is a randomized, double-blind, placebo controlled study to investigate the effect of intravenous thiamine (vitamin B1) on lactate, cellular oxygen consumption, global oxygen consumption and biomarkers of neurologic injury after out-of-hospital cardiac arrest (OHCA). Patients who have sustained return of spontaneous circulation (ROSC) after OHCA and have a lactate of 3 or greater will be eligible for the study. Enrolled patients will be randomized to intravenous thiamine 500mg twice daily for 5 doses or matching placebo (100cc normal saline). Blood will be drawn at several time points and patients will be connected to a noninvasive monitor for continuous measurement of global oxygen consumption. The primary endpoint is change in lactate level. Secondary endpoints include change in pyruvate dehydrogenase activity, change in cellular and global oxygen consumption, change in NSE and S100 (biomarkers of neurologic injury) and CPC-E score (a score that assesses neurologic and functional impairment) at hospital discharge, 30 and 90 days.
