The Thiamine Administration After Cardiac Surgery Trial

Summary

Thiamine (Vitamin B1) is essential for cell function and as a co-factor of the enzyme Pyruvate Dehydrogenase to initiate the Krebs cycle and thus the aerobic metabolism of glucose. We hypothesize that thiamine supplementation improves the clearance of lactate in the first 24 hours after cardiac surgery with extracorporeal circulation in patients with high lactate concentration.
