A cuffed oropharyngeal airway has recently been introduced which has larger internal dimensions than a comparable Guedel airway. This allows a ventilation/exchange bougie, the Aintree Intubation Catheter, mounted on a fibreoptic laryngoscope to pass through it. Its 15-mm connector and pharyngeal cuff suggested the possibility of using a Rüsch sealed-port angle piece to allow ventilation through the oropharyngeal airway during fibreoptic laryngoscopy. This study investigated using this equipment to intubate the trachea through the cuffed oropharyngeal airway in paralysed patients, whilst maintaining ventilation manually with a Bain system. In 20 patients, airway control was satisfactory throughout and tracheal intubation was accomplished without complications. The cuffed oropharyngeal airway was easy to manipulate to improve a suboptimal fibreoptic view of the larynx. This may give it an advantage over the laryngeal mask airway when used as a ventilation/intubation conduit.
最近推出了一种带套囊的口咽气道，其内部尺寸比同等的 Guedel 气道更大。这使得安装在纤维喉镜上的通气/交换探条（Aintree 插管导管）能够穿过它。其 15 毫米的接头和咽部套囊提示了使用 Rüsch 密封端口角形接头的可能性，以便在纤维喉镜检查期间通过口咽气道进行通气。本研究调查了在麻痹患者中使用该设备通过带套囊的口咽气道进行气管插管，同时使用 Bain 系统手动维持通气的情况。在 20 例患者中，气道控制始终令人满意，气管插管顺利完成且无并发症。带套囊的口咽气道易于操作，可改善不理想的喉部纤维镜视野。当用作通气/插管通道时，这可能使其比喉罩气道更具优势。
