Abstract

Lidocaine jelly or spray is usually applied to tracheal tube cuffs as lubricants, and we encountered some cuff troubles in using the spray. Damages on polyvinyl chloride (PVC) tracheal tube cuffs by applying lidocaine spray have been reported. We studied cuff injury with 5 kinds of tracheal tubes (PVC and non-PVC cuffs) with three different substances (normal saline, lidocaine jelly and lidocaine spray). No tracheal tube cuffs were damaged by normal saline and lidocaine jelly, while lidocaine spray changed the shape of some tracheal tube cuffs (PVC and non-PVC). Therefore, we recommend to apply lidocaine jelly on tube cuffs rather than lidocaine spray, even on non-PVC cuffs.

摘要

利多卡因凝胶或喷雾剂通常作为润滑剂应用于气管导管的套囊，而我们在使用喷雾剂时遇到了一些套囊问题。已有报道称，应用利多卡因喷雾剂会对聚氯乙烯（PVC）气管导管套囊造成损害。我们用5种气管导管（PVC和非PVC套囊）以及三种不同物质（生理盐水、利多卡因凝胶和利多卡因喷雾剂）研究了套囊损伤情况。生理盐水和利多卡因凝胶未对气管导管套囊造成损害，而利多卡因喷雾剂改变了一些气管导管套囊（PVC和非PVC）的形状。因此，我们建议在导管套囊上应用利多卡因凝胶而非利多卡因喷雾剂，即使是在非PVC套囊上。
