Accidental inhalation injury of phosgene gas leading to acute respiratory distress syndrome.

Irritant gas exposure may lead to significant respiratory distress as is seen in the present case of 25 year old male worker who suffered accidental phosgene inhalation. He remained asymptomatic for six hours but later landed up in Acute Respiratory Distress Syndrome in the hospital and required ventilatory support. No investigative feature is diagnostic of the nature of irritant gas. Similarly there is no antidote available to the phosgene. Only timely administered supportive management may lead to successful outcome.
