NCT02322892

Brief Summary

The main purpose of this pilot study is to test the effects of thiamine (vitamin B1) administration before and after major cardiac surgery. Half of patients will receive thiamine and the other half will receive placebo. The investigators' main hypothesis is that thiamine will improve cellular oxygen consumption and lead to decreased levels of post-operative lactate levels and ultimately improved patient outcomes.
