[Cuff failure in tracheal tubes sprayed with lidocaine].
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.
