介入放射法引导严重气道狭窄患者气管插管的效果

严重气道狭窄患者12例,年龄34～87岁,体重50～80kg,ASA分级Ⅳ或Ⅴ级,X线透视下,采用介入放射法引导,经口腔插入导丝.沿导丝置入鞘管与扩张器套装,套上合适型号的气管导管,固定导丝,将鞘管及扩张器越过狭窄气管,插至隆突上方或一侧主支气管内,固定鞘管及扩张器,气管导管顺鞘管越过狭窄的气管段插至狭窄的气道下方,固定气管导管,迅速将鞘管、扩张器和导丝从气管导管内撤出,外固定气管导管.12例严重气道狭窄患者气管插管均成功,插管时间1～5 min,未见相关严重并发症发生.

Efficacy of method of interventional radiology for guiding tracheal intubation in patients with severe airway stenosis

Twelve ASA Ⅳ or Ⅴ patients with severe airway stenosis, aged 34-87 yr, weighing 50-80 kg,were enrolled in the study. The guidewire and endotracheal tube were inserted through the oral cavity under the guidance of the method of interventional radiology. The expandor was then exchanged and the endotracheal tube was placed in the suitable position within the trachea along the expandor under X-ray guidance. Endotracheal intubation was technically successful in all patients, without serious complications in the process. The intubation time was 1-5 min.
