An Evaluation of the Laryngeal Mask Airway Supreme[Tm] in 100 Patients (Equipment) (Report‪)‬

The Laryngeal Mask Airway Supreme[TM] (LMA Supreme, The Laryngeal Mask Company, Singapore) is a relatively new single-use laryngeal mask airway which incorporates features of the LMA ProSeal[TM], LMA Fastrach[TM] and LMA Unique[TM]. The LMA Supreme has an anatomically shaped semi-rigid airway tube similar to the LMA Fastrach, which enables insertion without the need for an introducer or for the operator to insert his/her fingers into the patient's mouth. The LMA Supreme has a gastric access channel built within the airway tube. It has a high-volume low-pressure cuff that is structured to minimise folding over during insertion. It also has a fixation tab to aid fixation of the device after insertion. Early work on the LMA Supreme found high success rates of insertion, and a study comparing the LMA Proseal and LMA Supreme in 36 female patients found similar insertion success rates, glottis seal pressure and gastric access. (1,2) The LMA Supreme has also been used successfully in resuscitation and in the management of difficult airways. (3-5) In this study, we investigated the clinical efficacy of the LMA Supreme in 100 patients with normal airways undergoing general anaesthesia for elective surgery in our institution.
