Abstract
Methemoglobinemia after Local Anesthesia with Prilocaine in a Newborn after Aortic Coarctation Repair: A Case Report
Highlights
Methemoglobin is the oxidized form of hemoglobin in which the iron in the heme component is oxidized from ferrous (+2) to ferric (+3) state
Complications related to local anesthesia are rare, it may occur especially in pediatric population when used in large doses exceeding the safe limits
In this case report; we present methemoglobinemia that has occured secondary to 2 mg/kg 2% (6.5 mg) prilokaine which was used as intercostal injection for postoperative analgesia for the 3-days-old, 3250 gram, newborn baby who underwent aortic coarctation repair with left thoracotomy
Summary
Methemoglobin is the oxidized form of hemoglobin in which the iron in the heme component is oxidized from ferrous (+2) to ferric (+3) state. Prilocaine, widely used local anesthetic, can cause methemoglobinemia in pediatric patients even in therapeutic doses. In this case report; we present methemoglobinemia that has occured secondary to 2 mg/kg 2% (6.5 mg) prilokaine which was used as intercostal injection for postoperative analgesia for the 3-days-old, 3250 gram, newborn baby who underwent aortic coarctation repair with left thoracotomy.
