We describe a case of herniation of an endotracheal tube with a high volume and low pressure cuff. In contrast with the conventional endotracheal tube with a low volume and high pressure cuff, which, after recognition of cuff herniation, can be deflated, the herniation of this type of tube could not be resolved in such a way. The large and soft cuff material had spread itself over the tube tip, as a result of the herniation and this was aggravated by deflation, making it impossible to adequately ventilate the patient. Pulse oximetry turned out to be a most helpful way of monitoring the seriousness of the situation, in which the patient was fully covered by sterile drapes.
我们描述了一例带有大容量低压套囊的气管内导管套囊疝出的病例。与传统的小容量高压套囊气管内导管不同，后者在识别出套囊疝出后可放气，而这种类型导管的疝出无法通过这种方式解决。由于疝出，大而柔软的套囊材料蔓延到了导管尖端，放气使其情况恶化，导致无法充分为患者通气。脉搏血氧饱和度测定结果证明是监测病情严重程度的最有用方法，当时患者全身被无菌手术单覆盖。
