Web1 de jun. de 2006 · Lactate concentrations >5 mmol litre −1 with severe metabolic acidosis predicts high mortality. Impaired lactate clearance, rather than hypoxic tissue production of lactate, is the cause of hyperlactaemia in stable septic patients. The normal plasma lactate concentration is 0.3–1.3 mmol litre −1. 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).
