Overview

Educational review uncovers diverse non-hypoxic etiologies of hyperlactatemia in critically ill patients, indicating the need for structured diagnostic algorithms and targeted management.

Key Points

To review the pathophysiology, clinical etiologies, diagnostic evaluation, and management strategies for type B lactic acidosis and related non-hypoxic lactate disorders.
Synthesized pathophysiological mechanisms and classifications of type B and D-lactic acidosis from current clinical literature.
Evaluated non-hypoxic drivers of hyperlactatemia across underlying comorbidities, drug and toxin exposures, inborn errors of metabolism, and mechanical circulatory support.
Formulated a practical diagnostic workflow and targeted therapeutic framework for unexplained hyperlactatemia.
Classified type B lactic acidosis into three central etiologies: systemic comorbid diseases, toxic or pharmacologic interference, and inborn metabolic errors.
Highlighted that standard clinical assays fail to detect D-lactic acidosis, risking delayed diagnosis in susceptible patients.
Established a structured diagnostic algorithm directing clinicians away from assuming tissue hypoperfusion and toward treating specific underlying triggers.
