The Combitube is a twin lumen device designed to establish the airway after blind insertion. Under general anaesthesia a rigid cervical collar was used to immobilise the neck in 15 ASA 1 and 2 patients. Insertion of the Combitude airway was then attempted. In 10/15 (66%) patients, blind insertion was not possible. In 5/15 (33%) successful blind insertions the Combitube entered the oesophagus on each occasion. In 8/10 of the failures, re-insertion of the Combitude was attempted with the aid of a Macintosh laryngoscope. In 6/8 cases (75%) satisfactory placement was then possible with the Combitube again entering the oesophagus on each occasion. Ventilation was satisfactory in all patients when insertion was successful. Blood staining of the Combitube was present in 7/15 (47%) patients. The Combitude cannot be recommended for use in patients whose necks are immobilised in rigid cervical collars.
双腔通气道是一种双腔装置，设计用于在盲插后建立气道。在全身麻醉下，对15例美国麻醉医师协会（ASA）分级为1级和2级的患者使用硬式颈托固定颈部，然后尝试插入双腔通气道。在15例患者中，10例（66%）无法进行盲插。在15例患者中有5例（33%）成功进行了盲插，每次双腔通气道均进入食管。在10例失败病例中的8例，借助麦氏喉镜尝试再次插入双腔通气道。在8例中的6例（75%），随后双腔通气道再次进入食管，放置成功。插入成功时所有患者通气均良好。15例患者中有7例（47%）双腔通气道出现血染。不推荐在颈部用硬式颈托固定的患者中使用双腔通气道。
