Treatment of empyema thoracis in children is generally performed via tube thoracostomy under local anesthesia. Prilocaine, the most preferred local anesthetic agent, is also the most common cause of acquired toxic methemoglobinemia even in therapeutic doses. In this article, we present a 10-year-old boy who developed cyanosis after chest tube insertion under local anesthesia due to empyema and diagnosed as toxic methemoglobinemia. Methemoglobin level was measured as 18.7% and patient was successfully treated with ascorbic acid.
