An audit of the single use portex laryngeal mask

We performed an audit of the insertion of the Single Use Portex Laryngeal Mask in 400 patients. Insertion was successful at first attempt in 335 out of 400 patients (83.8%). However in 15 patients (3.8%), the Portex laryngeal mask could not be placed despite repeated attempts. In 12 of these 15 patients (80%), a standard Laryngeal Mask Airway (LMA) was successfully placed. After the completion of the audit, 22 out of 29 anaesthetists (75.9%), who had inserted greater than or equal to5 Portex laryngeal masks, considered it inferior to the standard LMA. It would appear to us that the Portex laryngeal mask might need some design modifications to be a real alternative to the standard LMA.
