The NAP4 report recommends using a bite block with an LMA.
The Flexi-LMA plus bite block is the only flexible LMA with an integral sliding bite block with a locking mechanism allowing customised placement of the bite block. It has a soft consistency to reduce dental damage while still preventing tube occlusion.
Guedels airways are not recommended for use as bite blocks
– may cause uvular oedema
