Abstract
Anesthesia risks for surgery of airway foreign body removal are very high. 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.

Summary
Children younger than 3 years’ old are at high risk of airway foreign body (FB) aspiration [1] [2]. A time series observation of children undergoing rigid bronchoscopy for an inhaled foreign body revealed that the incidence of pneumothorax and death was 0.3% and 0.1% [3]. Rigid bronchoscopy under general anesthesia is the usual surgical technique for foreign body removal [4] [5] [6]. Anesthesia risks for surgery of airway foreign body removal are very high, and the mortality is very high. Spontaneous respiratory has lower risk to cause tension pneumothorax compared with manual jet ventilation.
