Rev Med Liege 2022, 77(7-8),435-439Abstract : We report the case of a 29-year-old man admitted to the emergency department for dyspnea and changes in mental status during a festivity. Clinically the patient presented a central cyanosis refractory to the administration of high concentration of oxygen. The consumption of poppers is increasingly used by young people for recreational purposes because they are inexpensive and easy to acquire. Methemoglobinemia is a potentially serious and little known complication of popper intoxication. This condition, known as «methemoglobinemia», was suspected by the emergency physician and confirmed through non-invasive measurement of methemoglobinemia in arterial blood gases. The early recognition of methemoglobinemia and prompt treatment allowed a favourable evolution of our patient avoiding the development of multi-systemic organ failure or even death.
