Summary We studied the LMA Supreme ™ in 100 elective, anaesthetised, healthy patients assessing: ease of use, airway quality, anatomical and functional positioning, airway leak and complications. Insertion was successful on first, second or third attempt in 90, nine and one patient respectively. Thirty manipulations were required in 22 patients to achieve a clear airway. Median [interquartile (range)] insertion time was 18 [10–25 (5–120)] s. During ventilation, an expired tidal volume of 7 ml.kg −1 was achieved in all patients. Median [interquartile (range)] airway leak pressure was 24 [20–28 (13–40)] cmH 2 O. On fibreoptic examination via the device, vocal cords were visible in 83 patients (85%). During maintenance, five patients (5%) required 13 airway manipulations. There was one episode of minor regurgitation, without aspiration. Other complications and patient side‐effects were mild and few. The LMA Supreme is easily and rapidly inserted, providing a reliable airway and good airway seal. Further studies are indicated to assess safety and performance compared to other supraglottic airway devices.
