Abstract
AbstractBackgroundNitrogen dioxide (NO2) is known to cause lung injury, but there is no established treatment for acute respiratory distress syndrome (ARDS) caused by NO2 inhalation.Case PresentationA 35‐year‐old man was accidentally exposed to NO2 fumes and presented to the emergency department. On admission, his oxygen saturation was 87% on ambient air and he was diagnosed with ARDS caused by NO2 inhalation and immediately intubated; however, hypoxemia and hypercapnia were not ameliorated. Hence, veno‐venous extracorporeal membrane oxygenation (V‐V ECMO) was introduced and the ventilator settings were set for lung‐protective ventilation. Methylprednisolone was also administered. After the initiation of these treatments, oxygenation gradually improved. Therefore, ECMO was weaned off on day 11 and he was extubated on day 12.ConclusionLung injury caused by NO2 inhalation can cause ARDS, and lung‐protective ventilation with V‐V ECMO induction, as well as glucocorticoid administration, may be effective for this condition.
