Thiamine Deficiency
Current UK practice suggests that patients at risk of Thiamine deficiency – dependent drinkers, malnourished patients and those with vomiting or suspected Wernickes, should receive parenteral thiamine, usually IV Pabrinex, rather than relying on oral thiamine alone. Oral thiamine is more appropriate for ongoing maintenance.
The key teaching point that thiamine should be given before glucose where possible should be retained. [12]
