As thiamin is an essential co-factor in carbohydrate. Based on our findings, a delay in giving glucose to hypoglycemic patients cannot be recommended at this time, although prompt thiamine supplementation after or concurrent with a return to normoglycemia is recommended.Ĭopyright © 2012 Elsevier Inc. The body needs thiamin to convert carbohydrates into glucose, the main source of energy in the body. Thiamine before glucose to prevent Wernicke encephalopathy: examining the conventional wisdom JAMA. Mounting case report evidence suggests that prolonged glucose supplementation without the addition of thiamine can be a risk factor for the development of Wernicke encephalopathy. Thiamine before glucose to prevent Wernicke encephalopathy: examining the conventional wisdom. True clinical research about the question of whether or not a glucose load can precipitate acute onset of Wernicke encephalopathy is lacking. There were 13 case reports/series, 4 animal studies, and 2 expert opinion articles. if this also exists, then give thiamine before glucose as glucose can precipitate the symptoms of Wernickes in. No evidence rose above the level of case report/series. Bottom line: Giving glucose prior to thiamine will not precipitate an acute Wernicke’s encephalopathy. Therefore, thiamine should be given first so that when the glucose is given, the glucose will more likely be utilized to form ATP and prevent the acceleration of cell damage/death to structures in the brain. Nineteen papers were ultimately identified and evaluated. The quality and content of each article was evaluated by the authors using the American Academy of Emergency Medicine literature review guidelines. Pertinent references were traced back to their sources and also included in the literature review. Mounting case report evidence suggests that prolonged glucose supplementation without the addition of thiamine can be a risk factor for the development of. TK is found in the cytosol of most tissues.

We sought to evaluate the published evidence describing the commonly held belief that thiamine supplementation must be given before glucose in hypoglycemic patients to prevent Wernicke encephalopathy.Īrticles were identified through computerized searches of MEDLINE and other online sources. By these reactions, thiamin directs glucose either to glycolysis or to the pentose pathway, which generates ribose (required for DNA) while reducing the production of glucose metabolites, a feature of potential import in mitigating diabetic pathology. Alcohol and Dextrose Injections USP should be given to a pregnant woman only if. The prevailing teaching in medical school curricula and in medical textbooks is that if thiamine deficiency is suspected, thiamine supplementation should be given before administering glucose.
