A plastic truncated conical tracheostomy plug passed down the outer cannula of a Jackson tracheostomy tube and into the lungs of a respirator-dependent man during the monthly change of the inner cannula. Despite repeated flexible and rigid bronchoscopic visualization, attempts at dislodgement were unsuccessful. An exploratory thoracotomy was also unsuccessful in recovering the plug. Seventeen days postaspiration, with percussion and postural drainage, the patient expectorated the plug, even in the absence of the cough reflex. Such plugs have now been modified by passing a ring through the hole to prevent aspiration.
在每月更换杰克逊气管造口管内套管期间，一个塑料截头圆锥形气管造口塞经气管造口管外管进入一名依赖呼吸机的男子肺部。尽管反复进行了柔性和刚性支气管镜检查，但试图取出该塞子均未成功。开胸探查也未能找回该塞子。误吸17天后，通过叩击和体位引流，患者咳出了该塞子，即便当时他没有咳嗽反射。现在，此类塞子已做了改进，在孔中穿过一个环以防止误吸。
