Usefulness of central venous saturation as a predictor of thiamine deficiency in critically ill patients: a case report.

The current case showed the relation between thiamine deficiency and high ScvO2. A literature review also suggested that thiamine deficiency is associated with high ScvO2. Thiamine deficiency causes impaired tissue oxygen extraction, which could lead to high ScvO2. In this context, high ScvO2 might serve as a predictor of thiamine deficiency in critically ill patients.
