Abstract

Methemoglobinemia is characterized by varying degrees of cyanosis due to increased hemoglobin concentrations containing oxidized iron. Prilocaine is a widely used local anesthetic and can cause methemoglobinemia in infants even in therapeutic doses. We present two female infants (younger than 2 months) who developed severe cyanosis after transcatheter pulmonary balloon valvuloplasty and were diagnosed with toxic methemoglobinemia. Both infants were anesthetized with local prilocaine application before balloon valvuloplasty. Methemoglobin levels of the patients were measured as 49.6% and 37.7%, respectively. Both were successfully treated with intravenous methylene blue and ascorbic acid.

Özet

Methemoglobinemi, okside demir içeren hemoglobin miktarındaki artışa bağlı olarak, değişen derecelerde siyanozla kendini gösteren bir tablodur. Prilokain klinikte sık kullanılan bir lokal anesteziktir ve süt çocuklarında tedavi dozunda bile edinsel methemoglobinemiye neden olabilmektedir. Bu yazıda, transkateter pulmoner balon valvüloplasti işlemi sonrasında ciddi siyanoz gelişen ve toksik methemoglobinemi tanısı konan iki kız bebek sunuldu. Yaşları 2 ayın altında olan hastalara, balon valvüloplasti işlemi öncesinde prilokain ile inguinal bölgeye lokal anestezi uygulanmıştı. Kan methemoglobin düzeyleri %49.6 ve %37.7 ölçülen hastalar intravenöz metilen mavisi ve askorbik asit ile başarılı bir şekilde tedavi edildi.
