TY - JOUR PY - 2022// TI - Two cases of fatal methemoglobinemia caused by self-poisoning with sodium nitrite: A case report JO - Medicine (Baltimore) A1 - Mun, Sung Hoon A1 - Park, Gwan Jin A1 - Lee, Ji Han A1 - Kim, Young Min A1 - Chai, Hyun Seok A1 - Kim, Sang Chul SP - e28810 EP - e28810 VL - 101 IS - 7 N2 - RATIONALE: Sodium nitrite intoxication reportedly causes severe methemoglobinemia. Recent studies reported that most clinically significant cases resulted from intentional exposure in suicidal attempts. We describe 2 cases of severe methemoglobinemia secondary to intentional sodium nitrite intoxication in suicidal attempts. PATIENTS CONCERNS: A 26-year-old man and 20-year-old woman attempted suicide by taking sodium nitrite, and were brought to the emergency department. DIAGNOSIS: The male patient collapsed at the scene. He ingested approximately 18 g of sodium nitrate, and his methemoglobin level was 90.3%. The female patient was conscious, but was cyanotic. She ingested approximately 12.5 g of sodium nitrite, and her methemoglobin level was 54.6%. INTERVENTIONS: The male patient received advanced cardiac life support in the emergency department. Methylene blue was immediately administered for the female patient. OUTCOMES: The male patient died despite aggressive resuscitation. The female patient's cyanosis resolved, and her methemoglobin level decreased to 1.2% 3 hours later. LESSONS: The immediate administration of methylene blue in severe methemoglobinemia patients prevented fatal consequences. The public should be informed about the accessibility and toxicity of sodium nitrite.
