T51.1
Toxic effect of methanol
Clinical Classification Guidelines
Inclusion Terms
- Toxic effect of methyl alcohol
Medical Intelligence & Overview
Methanol, also known as methyl alcohol, is a type of alcohol that is used in industrial products like antifreeze, solvents, and beauty products. When someone is exposed to high levels of methanol, it can have serious health effects, affecting the eyes, nervous system, and other organs. The ICD-10 code T51.1 specifically refers to the toxic effect caused by methanol poisoning, which requires prompt medical attention to prevent long-term damage or death.
Causes & Symptoms
Clinical Causes: Accidental ingestion of methanol-containing products such as windshield washer fluid, antifreeze, or cleaning agents. Intentional ingestion in cases of attempted poisoning or suicidal attempts. Inhalation of methanol vapors in poorly ventilated environments where methanol is used or stored. Absorption through the skin, especially with prolonged or direct contact with methanol-containing substances.
Key Symptoms: Visual disturbances including blurred vision, seeing halos or a “snow storm” effect, which can progress to complete blindness. Headache, dizziness, and fatigue. Nausea, vomiting, and abdominal pain. Difficulty walking or coordinating movements due to neurological effects. Respiratory distress in severe cases. In extreme poisoning, metabolic acidosis and central nervous system depression may occur.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical assessment and laboratory tests. Healthcare providers may perform blood tests to measure blood methanol levels and check for metabolic acidosis. An eye examination can reveal characteristic visual changes. Imaging studies are rarely utilized but may be used to assess brain or retinal damage if necessary.
Treatment Protocols: Immediate medical intervention is critical in cases of methanol poisoning. Treatment options typically include:
