Methanol Poisoning.

Area of Science:

• Toxicology
• Emergency Medicine
• Biochemistry

Background:

• Methanol consumption poses significant mortality risks, often presenting as clusters of cases requiring urgent medical attention.
• Understanding the pathophysiology of methanol toxicity is critical for effective clinical management by healthcare professionals.

Purpose of the Study:

• To elucidate the clinical presentation and emergency management strategies for methanol poisoning.
• To explain the physiological and biochemical basis of methanol toxicity.

Main Methods:

• Review of clinical presentations and established emergency protocols for methanol exposure.
• Explanation of metabolic pathways involving methanol conversion to toxic byproducts.

Main Results:

• Methanol is converted to formaldehyde by alcohol dehydrogenase, initiating rapid metabolic cascade.
• Symptoms manifest within 30 minutes, progressing to severe metabolic acidosis, seizures, hypoglycemia, and blindness within 12 hours if untreated.
• Acute kidney injury is a common complication requiring hemodialysis.

Conclusions:

• Key diagnostic tools include fundoscopic examination and arterial blood gas analysis.
• Management involves intravenous sodium bicarbonate, electrolyte correction, fomepizole or ethanol, folic acid, and hemodialysis.
• Immediate emergency department intervention followed by intensive care unit monitoring is vital for patient salvage and preventing sequelae.
