Abstract
Methemoglobinemia is a fatal complication of local anesthesia. We describe a case report of female neonate who developed severe methemoglobinemia after extraction of neonatal teeth conducted with general anesthesia plus local injection of Citanest-Octapressin® (propitocaine of approximately 10 mg/kg). Central cyanosis appeared within an hour after surgery. The percentage of methemoglobin reached up to 43.9%. Not only pediatric dentists but also anesthesiologists generally agree with the idea that local anesthesia provides various benefits in painful procedures in neonates. However, this case may serve as a warning when using Citanest-Octapressin®, which is still commercially available for neonatal patients.
