Abstract

Abstract : Background: Nowadays, it is getting easier to search information about helium‐assisted suicide online. Therefore, healthcare professionals must understand helium‐associated medical conditions. Case Presentation: A 27‐year‐old man was found with his head covered with a bag connected to a helium tank. Hyperbaric oxygen therapy was not given because his head computed tomography showed no cerebral vasculature air embolism and there was no obvious limb paralysis. The diagnosis was impaired consciousness with hypoxic encephalopathy; he needed mechanical ventilation for 2 days. He was discharged after intelligence tests with no obvious higher brain dysfunction. Conclusion: We successfully treated a patient with hypoxic encephalopathy due to helium inhalation. Our analysis suggests that the pathophysiology and appropriate intervention of helium intoxication might be different according to the devices used. Abstract : Pathophysiology and appropriate intervention of helium intoxication might be different according to the devices used. Cases of attempted suicide by using helium could increase in the future.
