ラリンゲルマスクを使用した小児気管支ファイバースコープ検査症例

Abstract

We report a case in which the laryngeal mask airway (LMA) was useful for pediatric flexible bronchoscopy under general anesthesia.A two-year-old girl was admitted to our hospital with the chief complaint of recurrence pneumonia and atelectasis. Anesthesia was induced with eithsevoflurane in 50% oxygen. Suxamethonium chloride was used for control ventilation.A size-2 laryngeal mask (ID 8mm) was then attached. The mask permitted the use of a fiberoptic bronchoscope with an external diameter of 3.2mm. Because of inadequate ventilation, the insertion of a 5.05mm, external diameter, fiberoptic bronchoscope for suction was not successful. Much pulurental mucus was observed in the left main bronchus, but tracheomalasiadid was not observed.However, we could make a full examination of the larynx, trachea and bronchial tree.In this case, throughout the bronchoscopy, adequate controlled ventilation could be achieved easily without excessive air leaks or airway resistance.We believe that this is a safe and useful technique for flexible fiberoptic bronchoscopy under general anesthesia, especially in pediatric cases.
