We describe a modification to the Guedel airway that improves suction and oxygenation during fibreoptic bronchoscopy. The entire roof of a Guedel airway was removed. Two 2.5-mm internal diameter tracheal tubes were inserted into the modified airway to allow continuous oxygen delivery and suction throughout fibreoptic bronchoscopy. It was tested as a single-use device in ten patients undergoing awake fibreoptic bronchoscopy under sedation and topical anasthesia. During the procedure there were no problems with either fogging of the lens or secretions in the pharynx. In addition, oxyhaemoglobin saturation, as monitored continuously by pulse oximetry, was >/= 97% in all patients.
我们描述了一种对古德气道（Guedel airway）的改良方法，该方法可在纤维支气管镜检查期间改善吸引和氧合。将古德气道的整个顶部移除。将两根内径为2.5毫米的气管导管插入改良后的气道，以便在整个纤维支气管镜检查过程中持续输送氧气和进行吸引。在10例接受镇静和局部麻醉下清醒纤维支气管镜检查的患者中，将其作为一次性装置进行了测试。在操作过程中，镜头未出现雾化现象，咽部也没有分泌物。此外，通过脉搏血氧饱和度仪连续监测的所有患者的氧合血红蛋白饱和度均≥97%。
