The results of 458 prolonged nasotracheal intubations are described in 435 infants and young children up to 5 years of age after open heart surgery, in whom the upper airway was normal. No deaths occurred which could be attributed to the technique, and no tubes became obstructed. Sub-glottic stenosis did not occur when a loose-fitting endotracheal tube was used, and stridor after extubation was rare. If necessary, the technique can be used with safety for several weeks.
本文描述了435例5岁以下接受心脏直视手术且上呼吸道正常的婴幼儿，共458次延长经鼻气管插管的结果。未发生可归因于该技术的死亡病例，也没有导管堵塞的情况。使用宽松适配的气管内导管时未发生声门下狭窄，拔管后喘鸣很少见。如有必要，该技术可安全使用数周。
