A 41-year-old man is brought to the emergency department because of blurry vision and confusion after drinking homemade alcohol. He is tachypneic. Laboratory studies show pH 7.12, HCO3− 9 mEq/L, elevated osmolar gap, and an increased anion gap. Which toxin is the most likely cause of this patient's acid-base disorder?
- A)Isopropyl alcohol
- B)Carbon monoxide
- C)Acetaminophen
- D)Ethylene glycol
- E)MethanolGABARITO
Explicação
Methanol intoxication causes an anion gap metabolic acidosis due to formic acid accumulation and is classically associated with visual disturbances. The elevated osmolar gap plus blurry vision strongly points to methanol rather than other toxic alcohols. Ver explicação completa e trilha adaptativa →
