Background Many extraglottic airway devices allow the direct passage of an adult‐sized tracheal tube, but this is not possible with the LMA ‐ Supreme TM . We evaluated the feasibility of using the LMA ‐ Supreme TM as a conduit for intubation in patients with known difficult airways. Methods Sixty‐eight adult patients, with preoperative predictors of difficult intubation, were scheduled for elective surgery under general anaesthesia. After assessing the direct laryngoscopy view, 23 patients with C ormack– L ehane III / IV were included in the study. An LMA ‐ Supreme TM was inserted, followed by the passage of a flexible bronchoscope loaded with an A intree I ntubation C atheter into the trachea. The bronchoscope and LMA ‐ Supreme TM were removed, and a tracheal tube was railroaded over the A intree I ntubation C atheter into the trachea.Results Tracheal intubation was successful in all patients using the above technique. SpO 2 was >95% during the intubation procedure. Conclusions We conclude that the LMA ‐ Supreme TM is a successful conduit for bronchoscopic/ A intree I ntubation C atheter‐guided intubation in patients with known difficult airway.
