Summary

Transient methanol exposure can cause toxicity through inhalation or skin absorption. Even with mild symptoms and normal labs, serum methanol levels are crucial for diagnosis.

Area of Science:

  • Toxicology
  • Emergency Medicine
  • Environmental Health

Background:

  • Methanol is a toxic alcohol that can be absorbed through inhalation and skin contact.
  • Acute methanol poisoning can lead to severe metabolic acidosis and organ damage.

Observation:

  • Two adult cases of methanol toxicity from brief vapor exposure are presented.
  • Patients exhibited mild headaches, normal physical exams, and normal anion gaps.
  • Peak serum methanol levels were 23 and 16 mg/dL.

Findings:

  • Transcutaneous and inhalational methanol absorption can occur even with transient exposure.
  • Clinical presentation and anion gap may not correlate with methanol levels in mild cases.
  • Serum methanol levels are essential for diagnosing toxicity in suspected exposures.

Implications:

  • Emergency physicians must consider methanol toxicity in patients with potential exposure, regardless of initial symptoms.
  • Empiric serum methanol level testing is recommended in cases of suspected methanol exposure.
  • Early recognition and diagnosis are vital to prevent severe methanol poisoning complications.
