Pressure damage to respiratory mucosa from overinflation of bronchial cuffs has been implicated as a cause of bronchial rupture, a rare but devastating complication of double-lumen endobronchial tubes (DLTs). We compared the pressure/volume characteristics of the bronchial cuffs of three different polyvinylchloride (PVC) DLTs and an equivalent sized red-rubber Robertshaw DLT. At the volume needed to seal effectively our bronchial model, two of the three PVC tube cuffs tested generated significantly less pressure than did that of the cuffs of the third PVC and the red-rubber Robertshaw tubes.
支气管套囊过度充气对呼吸道黏膜造成的压力损伤被认为是支气管破裂的一个原因，支气管破裂是双腔支气管导管（DLT）一种罕见但极具破坏性的并发症。我们比较了三种不同聚氯乙烯（PVC）双腔支气管导管以及一个同等尺寸的红色橡胶罗伯特肖双腔支气管导管的支气管套囊的压力/容积特性。在有效密封我们的支气管模型所需的容积下，所测试的三种PVC导管套囊中，有两种产生的压力明显低于第三种PVC导管和红色橡胶罗伯特肖导管的套囊所产生的压力。
