Abstract: | A new prototype of the laryngeal mask airway (LMA), the intubating
laryngeal mask airway (ILMA), was used to facilitate tracheal intubation in
100 fasted patients presenting for elective surgery. Alignment of the ILMA
with the larynx was assessed fibreoptically before intubation without the
investigator performing the intubation being aware of the view score. Ease
of intubation correlated with the view obtained and with the degree of
manipulation of the ILMA needed to achieve tracheal intubation. Intubation
was successful in 93 patients. Of the seven intubation failures, five
occurred in the first 20 patients. Conventional connection to the breathing
system and ventilation of the lungs of the patients were possible
throughout the intubation procedure.
