Web0. The common fear of administering lactate reveals a misunderstanding of LR and the role of lactate in shock states. First, LR contains sodium lactate (not lactic acid), and is therefore not acidotic. Second, lactate probably has a beneficial role as discussed above (although it is very rapidly metabolized). WebUnder normal conditions this reaction results in a lactate-to-pyruvate ratio of 10:1. All cells are capable of producing lactate. Tissues with a high metabolic rate (gut, brain, skeletal …
