A safe way to anaesthetize the patients is important. This report presented a case of an infant with a foreign body in the subglottic area, which was ultimately removed by rigid laryngoscopy under spontaneous respiratory using dexmedetomidine (DEX). A loading dose of DEX 4 μg·kg-1 and sevoflurane 2 MAC could provide adequate depth of anesthesia during inserting the rigid bronchoscopy, and DEX 3 μg·kg-1·h-1 was suitable for the maintance of anethesia with spontaneous respiratory. We considered that the maintenance of spontaneous respiration is one of the key points.展开更多
