It is easy to view the laryngeal aperature with a flexible fiberscope through a laryngeal mask airway (LMA). This is a case report that the LMA could facilitate a fiberscope-aided tracheal intubation easily.
Patient was a 59 year old female who had some limitation of mouth opening due to ankylosis o bilateral temporomandibular joints. After thiopental (200 mg) and succinylcholine chloride (50 mg) were given intravenously, a number 3 sized LMA was
inserted
and the lungs were ventilated via the LMA. The anesthesia circle system is then disconnected from the LMA and a fiberscope, with the proximal end jacketed with a well-lubricated, cuffless, 6-mm-ID endotracheal tube (ETT), was inserted into the
trachea
through the lumen of the LMA.
The 6-mm-ID ETT was threaded over the fiberscope into the trachea before fiberscope was withdrawn, and a tracheal tube exchanger was inserted through the ETT after enough ventilation for a while, followed withdrawal of the LMA and ETT. Finally,
we
can
make the 7 mm-ID ETT with cuff insert into the trachea over a tracheal tube exchanger very easily without any difficulties.
