Infant was an anesthetized with local prilocaine. Central cyanosis appeared six hour after surgery. The methemoglobine level reached to 23%. Subject was interned to intensive care unit and ascorbic acid therapy as well as O2 therapy with mask was started. The subjects sPO2 levels were %88 with the O2 therapy with mask.
