Deep sedation with sevoflurane insufflated via a nasal cannula in uncooperative child undergoing the repair of dental injury.

Sevoflurane, a potent volatile anesthetic, has been attempted to be used for procedural sedation. Because of lack of a commercially available sedation apparatus for sevoflurane administration, anesthetic gas delivery apparatus should be connected to general anesthetic machine for delivering sevoflurane gas. In this case, deep sedation was maintained during treatment of dental injuries involving the upper lip and incisor by sevoflurane insufflations via a nasal cannula. Especially, this may be advantageous in treating dental injuries involving upper lip and maxillary anterior teeth because the treatment is not disturbed during sevoflurane insufflations via a nasal cannula.
