A randomised comparison of the self-pressurised air-QTM intubating laryngeal airway with the LMA Unique™ in children.
We conducted a randomised trial comparing the self-pressurised air-Q™ intubating laryngeal airway (air-Q SP) with the LMA-Unique in 60 children undergoing surgery. Outcomes measured were airway leak pressure, ease and time for insertion, fibreoptic examination, incidence of gastric insufflation and complications. Median (IQR [range]) time to successful device placement was faster with the air-Q SP (12 (10-15 [5-18])) s than with the LMA-Unique (14 (12-17 [6-22]) s; p=0.05). There were no statistically significant differences between the air-Q SP and LMA-Unique in initial airway leak pressures (16 (14-18 [10-29]) compared with 18 (15-20 [10-30]) cmH2 O, p=0.12), an airway leak pressures at 10 min (19 (16-22 [12-30]) compared with 20 (16-22 [10-30]) cmH2 O, p=0.81); fibreoptic position, incidence of gastric insufflation, or complications. Both devices provided effective ventilation without the need for airway manipulation. The air-Q SP is an alternative to the LMA-Unique should the clinician prefer a device not requiring cuff monitoring during anaesthesia.
