Elevated lactate level predicts intensive care unit admissions ...

WebbTraditionally it was believed that elevated lactate is due to anaerobic metabolism, as a consequence of inadequate perfusion with low oxygen delivery to the tissues. This has largely been debunked. Most patients with sepsis and elevated lactate have hyperdynamic circulation with very adequate delivery of oxygen to the tissues. Webb27 apr. 2024 · Background L-lactate is the end product of anaerobic glycolysis. It is derived predominantly from white skeletal muscle, brain, skin, renal medulla and erythrocytes. Lactate dehydrogenase catalyses the reduction of pyruvate to lactate. There are two major clinical settings in which lactic acidosis occurs, conditions associated with hypoxia (e.g. …

Webb26 jan. 2015 · The predicted effect of crystalloids on blood acid-base status depends on their strong ion difference (SID). If you prefer to conceptualize pH using the Henderson-Hasselbach model, then you can think about SID in this context as equal to “bicarbonate equivalents” (e.g., LR contains 28 mM of lactate, which promptly generates 28 mM of … phenobarbital and etoh withdrawalGlucose metabolism begins with glycolysis, in which the molecule is broken down into pyruvate in ten enzymatic steps. A significant proportion of pyruvate is converted into lactate (usually 10:1). The human metabolism produces about 20 mmol/kg of lactic acid every 24 hours. This happens predominantly in tissues (especially muscle) that have high levels of the "A" isoform of the enzyme lactate dehydrogenase (LDHA), which predominantly converts pyruvate into lactate.
