Abstract

The aim of this review is to introduce about the issue of benzocaine and methemoglobinemia. Through blocking the pain during dental treatment, fear and anxiety of patients will be reduced. Thus, anesthetic agent containing benzocaine is commonly used while controlling the pain of patients during treatment. However, on May 28, 2018, the Ministry of Food and Drug Safety reported a medication safety report about restricting the use of benzocaine-containing agents in infants under 24 months and children. Also, they recommended a cautious use to adolescents and adults to prevent methemoglobinemia (MHb). This report was published due to an advice from Food and Drug Administration (FDA) on May 23, 2018. When using agents containing benzocaine, dentists must consider the probability of MHb and prepare for early diagnosis and appropriate action. Since 1930s, methylene blue is known to cure MHb patients. Therefore, the proper use of methylene blue for emergencies and diagnosis methods for early diagnosis of MHb should be familiar to dentists planning for the use of topical anesthetic agents. Dentists should be trained for emergency situation of MHb caused by the use of benzocaine.

치과치료 중에 통증을 유발할 수 있는 요소를 차단함으로써 환자의 공포와 두려움을 줄여줄 수 있다. 이를 위해 벤조케인을 함유한 도포마취제가 광범위하게 사용되고 있다. 그러나, 2018년 5월 28일 식품의약품안전처는 의약품 안전 서한을 통해 24개월 미만의 소아 및 영아에서 벤조케인 함유 제제의 사용을 금지하고 그 이상의 경우라 하더라도 메트헤모글로빈혈증(Methemoglobinemia, MHb)의 발생가능성이 있으므로 신중한 사용을 권고하였다. 이는 지난 5월 23일 미국 식품의약국(Food and Drug Administration, FDA)의 권고의 후속 조치로 시행된 것이다. 벤조케인을 함유한 제제를 사용하는 경우, 치과의사는 MHb의 발생가능성을 반드시 고려해야 하며 MHb의 조기 진단과 적절한 조치가 시행될 수 있도록 준비하고 있어야한다. MHb의 치료제는 메틸렌블루가 1930년대부터 이용되고 있다. 치과의사는 메틸렌블루의 적절한 사용법과 용량을 숙지하고, MHb의 조기 진단을 위한 방법과 진단 장비에 익숙해야 한다. 무엇보다도 환자의 안전에 대한 적절한 대비와 훈련이 필요할 것이다.
