Deep sedation with sevoflurane inhalation via a nasal hood for brief dental procedures in pediatric patients.

Nitrous oxide is widely used for dental sedation. However, weak potency of nitrous oxide requires additional sedatives for maintaining a deeper level of sedation. Sevoflurane, a mainstay in pediatric anesthesia, is a potent anesthetic agent. Some attempts have been made to use sevoflurane for conscious sedation. In this case, we successfully treat pediatric patients under deep sedation by sevoflurane inhalation without other sedatives. Sevoflurane may be useful for sedation in pediatric dental outpatient setting.
