Lactic acidosis, a common hospital condition, is defined by low pH and high lactate. Treatment focuses on the cause, with debated bicarbonate efficacy and risks associated with dichloroacetate.

Area of Science:

  • Biochemistry
  • Internal Medicine
  • Critical Care Medicine

Context:

  • Lactic acidosis is a frequent acid-base disorder in hospital settings.
  • It is characterized by arterial pH < 7.35 and arterial lactate > 5 mmol/L.
  • Two main types exist: Type A (hypoperfusion) and Type B (no apparent hypoxia).

Purpose:

  • To define lactic acidosis and its classifications.
  • To discuss current treatment strategies and their limitations.
  • To highlight the prognostic value of arterial lactate levels.

Summary:

  • Lactic acidosis involves low pH and elevated lactate, with Type B occurring in diverse conditions like diabetes and liver failure.
  • Treatment primarily targets the underlying cause; sodium bicarbonate's efficacy is debated due to potential adverse effects.

  • Dichloroacetate offers partial correction but carries risks with prolonged use.

    • Impact:

    • Arterial lactate levels serve as a reliable prognostic indicator in shock.
    • Sequential lactate measurements are crucial for patient monitoring and management.
    • Understanding lactate metabolism is key for effective therapeutic interventions.
