Approaching Acid-Based Disorders in ICU Patients

In ICU patients presenting with metabolic acidosis, it is crucial to assess both the anion gap metabolic acidosis and non-anion gap metabolic acidosis. Mnemonics like GOLDMARK for identifying anion gap disorders and RAGUS for non-anion gap disorders can aid in differential diagnosis. Recognizing patterns from labs and history, like toxic ingestions, cancer-related lactic acidosis, malnutrition, and renal failure, can guide targeted investigations.
