Although tracheal tube cuffs are well known to injure the trachea, attempts to design safer cuff systems have been only partially successful. In 14 dogs, we compared three models of high residual volume, low pressure cuffs, which are considered to be among the safest. Two were air-filled cuffs -- a maintained pressure cuff and a balloon reservoir cuff -- and the third was foam-filled. Tracheal dilatation was considerably more severe with mechanical ventilation than with spontaneous breathing, but the foam cuff produced significantly less dilatation (P less than .005) than the air-filled cuffs.
尽管气管导管套囊会损伤气管已是众所周知，但设计更安全套囊系统的尝试仅取得了部分成功。在14只狗身上，我们比较了三种高残余容积、低压套囊模型，它们被认为是最安全的套囊类型。其中两种是充气套囊——一种恒压套囊和一种球囊贮液套囊，第三种是泡沫填充套囊。与自主呼吸相比，机械通气时气管扩张明显更严重，但泡沫套囊产生的扩张明显小于充气套囊（P小于0.005）。
