What causes high lactate levels in babies?
Lactic acidosis—Infants with lactic acidosis present a difficult diagnostic problem. A high plasma lactate can be secondary to hypoxia, cardiac disease, infection, or convulsions, whereas primary lactic acidosis may be caused by disorders of pyruvate metabolism and respiratory chain defects.
What is the normal lactate level in children?
Currently, accepted normal serum lactate levels in children are ages 0-90 days: 1.1-3.5 mmol/L, ages 3-24 months: 1.0-3.3 mmol/L, and ages 2-18 years: 1.0-2.4 mmol/L.
What is a normal lactate value?
Normal lactate range is less than 2.3 mmol/L. At enrollment, patients in the second quartile (1.4 < lactate < 2.3 mmol/L) had significantly increased mortality and organ dysfunction compared with patients who had lactate ≤ 1.4 mmol/L (quartile 1) (P < 0.0001).
What is a normal serum lactate level?
Most labs define normal as 0.5 to 2.2 mmol/L for venous blood and 0.5 to 1.6 mmol/L for arterial blood. Serum lactate levels increase in lactic acidosis, severe dehydration, heart failure, respiratory failure, hemorrhage, ketoacidosis, severe infections, alcohol abuse, salicylate toxicity, shock, and liver disease.
What is the highest lactate level?
The concentration of blood lactate is usually 1-2 mmol/L at rest, but can rise to greater than 20 mmol/L during intense exertion. Blood lactate levels essentially serve as an indirect marker for biochemical events such as fatigue within exercising muscle.
Is it normal for newborns to lactate?
Witch’s milk or neonatal milk is milk secreted from the breasts of some newborn human infants of either sex. Neonatal milk secretion is considered a normal physiological occurrence and no treatment or testing is necessary.
What does high lactic acid levels mean?
A high lactic acid value means lactic acidosis, which can be caused by: Severe loss of water from the blood (dehydration). Blood problems, such as severe anemia or leukemia. Liver disease or liver damage that prevents the liver from breaking down lactic acid in the blood.
What is a critical lactate level?
The normal blood lactate concentration in an unstressed patient is 0.5-1 mmol/L. Patients with critical illness can be considered to have normal lactate concentrations of less than 2 mmol/L.
