Notes:
We performed a randomised, crossover, single-blind trial among 168 patients, to compare the single-use SoftSeal™ and LMA Unique™ laryngeal mask airways in spontaneously breathing adults. Size-3 and -4 laryngeal mask airways, inserted by experienced anaesthetists, performed equivalently for successful first-time placement (148 (91%) vs 155 (96%) for the SoftSeal™ and LMA Unique™, respectively). The SoftSeal™ was more often rated as difficult to insert (27 (17%) vs 4 (3%); p 〈 0.001) and was more likely to show evidence of mucosal trauma after the first insertion (14 (10%) vs 5 (4%); OR 1.3 (95% CI 1.3–11.3); p 〈 0.05). The fibreoptic view of the larynx was better through the SoftSeal™ (vocal cords not visible in 27 (17%) vs 44 (27%); p 〈 0.05) and it more frequently provided a ventilation seal at 20 cmH2O (93 (59%) vs 62 (39%); OR 2.15 (CI 1.44–3.21); p 〈 0.001). In contrast to the LMA Unique™, its cuff pressure did not increase during nitrous oxide anaesthesia (median (IQR [range]) decrease 3 (− 20–23 [-40–94]) cmH2O vs increase of 16 (−2–39 [−54–112]) cmH2O; p 〈 0.01). Both devices were equivalent for the success of first-time insertion and performed satisfactorily clinically. There were some performance differences, but either appears suitable for airway management in spontaneously breathing patients.
