Summary

Severe methanol intoxication from inhalation requires prompt recognition and treatment. This case highlights that inhaled methanol poisoning is as dangerous as ingested methanol and necessitates urgent medical intervention, including haemodialysis and ethanol therapy.

Area of Science:

  • Toxicology
  • Emergency Medicine
  • Environmental Health

Background:

  • Methanol is a toxic alcohol commonly found in industrial solvents.
  • Exposure can occur through ingestion, inhalation, or skin absorption.
  • Severe methanol poisoning can lead to significant morbidity and mortality, often due to delayed diagnosis and treatment.

Observation:

  • A 38-year-old man presented with symptoms of severe methanol intoxication, including visual disturbances, photophobia, hyperventilation, and nausea.
  • The patient reported a 36-hour history of inhaling methanol in a poorly-ventilated laboratory.
  • Initial laboratory results revealed severe metabolic acidosis and a toxic serum-methanol level.

Findings:

  • The patient received treatment with acute haemodialysis and ethanol infusions.

  • Following 9 hours of haemodialysis, serum-methanol levels decreased below toxic thresholds.
  • The patient experienced complete symptom resolution and was discharged from the intensive care unit within 24 hours.

    • Implications:

    • This case represents the first documented instance of severe methanol intoxication resulting from inhalation exposure.
    • Inhalation of methanol poses a serious health risk comparable to ingestion and requires similar urgent medical management.
    • Early recognition and prompt treatment are critical to prevent severe complications and mortality in methanol poisoning cases.
