Cuff protection for nasotracheal intubation

The passage of a tube through the nose to the epipharynx is potentially dangerous during the nasotracheal intubation because of the possibility of cuff damage, obstruction of the tube, the impossibility of advancing the tube and contamination. It seems therefore useful to protect the cuff e.g. by a finger stall, but using this procedure complications can occur which are reported. A better solution to protect the cuff will be shown.
