Podcast 608: Another Elevated Lactate?

Podcast 608: Another Elevated Lactate?

Contributor: Jared Scott, MD

Educational Pearls:

  • Lactate is a byproduct of anaerobic metabolism or tissue hypoperfusion
  • Though typically associated with severe sepsis, hyperlactatemia can be caused by vigorous exercise, seizures, liver failure, asthma exacerbations, albuterol, metformin, antiretroviral drugs, and propofol
  • Liver failure can lead to an inability to clear lactate, or convert it back to glucose byproducts, instead of an overproduction of lactate
  • Always remember the other causes of elevated lactic acid besides sepsis but also remember sepsis!
