Abstract

A statistically significant (p = 0.049) increase in methemoglobin (MetHb), which did not exceed normal values, was noted 8 h after application of 1 g of EMLA (Eutectic Mixture of Local Anesthetics) to the foreskin of 10 normal newborns to reduce pain associated with circumcision. The highest MetHb concentration observed was 3 g/l (toxic > 50 g/l). No infant showed clinical signs of methemoglobinemia. We conclude that EMLA is safe to use as a local anesthetic in term neonates.
