Manikin studies\u2019 data cannot accurately be extrapolated to real-life scenarios and inherent differences in design and materials of newer products may affect their clinical performance.<jats:italic>Methods<\/jats:italic>. Hence, we compared the AMBU\u00ae Aura-i\u2122 and LMA Supreme\u2122 in this randomized trial involving 100 ASA 1-2 unparalysed anaesthetised patients undergoing minor gynaecological surgery. Investigators had &lt;20 Aura-i insertions. Primary outcome was time to achieve effective ventilation and secondarily insertion parameters, oropharyngeal leak pressures (OLP), fibreoptic positioning, and pharyngeal morbidity. The position of the Ambu Aura-i was evaluated with the Ascope; the fiberoptic view of the glottis was scored on a five-point scale.<jats:italic>Results<\/jats:italic>. 43 (86%) AMBU Aura-i and 44 (88%) LMA Supremes were successfully inserted on first attempt (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">0.59<\/mml:mn><\/mml:math>), with similar ease (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">0.79<\/mml:mn><\/mml:math>), and comparable times to first capnogram, mean (SD) 18.2 (6.0) versus 17.3 (6.4) sec,<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">0.9<\/mml:mn><\/mml:math>.

There was no difference in ease of insertion or adjustment manoeuvres to aid ventilation. 90% of patients had good positioning of Aura-i on fibreoptic check, yielding a view of the vocal cords and epiglottis. In 5 patients (10%), the vocal cords were not seen, but ventilatory function was unaffected.<jats:italic>Conclusions<\/jats:italic>. The Aura-i handled well in novices hands, with comparable times to insert and establish ventilation, similar leak pressures, and successful first attempt insertion rates compared to the LMA Supreme.<\/jats:p>","DOI":"10.1155\/2016\/4717061","type":"journal-article","created":{"date-parts":[[2016,10,25]],"date-time":"2016-10-25T17:01:55Z","timestamp":1477414915000},"page":"1-8","source":"Crossref","is-referenced-by-count":5,"title":["The AMBU\u00ae Aura-i\u2122 Laryngeal Mask and LMA Supreme\u2122: A Randomized Trial of Clinical Performance and Fibreoptic Positioning in Unparalysed, Anaesthetised Patients by Novices"],"prefix":"10.1155","volume":"2016","author":[{"given":"Zanahriah","family":"Yahaya","sequence":"first","affiliation":[{"name":"Department of Women\u2019s Anaesthesia, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9594-3009","authenticated-orcid":true,"given":"Wendy H.","family":"Teoh","sequence":"additional","affiliation":[{"name":"Private Anaesthesia Practice, Wendy Teoh Pte.
