Abstract/OtherAbstract:
Two new supraglottic airway devices, the LMA Supreme™ (LMA) and the i-gel™, offer potential benefits when inserted by inexperienced operators. This study compared the insertion success rate and ventilation profile between the LMA Supreme and the i-gel when inserted by operators without previous airway management expertise. Following a short lecture and manikin training, airway novices were randomly allocated to insert either the LMA Supreme or the i-gel into 80 patients undergoing breast surgery. The primary outcome was first-time success rate, and secondary outcomes were overall success rate, insertion time, airway leak pressure, tidal volume during pressure controlled ventilation at 17 cmH(2) O, and adverse events. First-time insertion success rate was significantly higher for the LMA Supreme than the i-gel (30/39 (77%) vs 22/41 (54%); p = 0.029). Significantly more placement failures occurred with the i-gel (6 vs 0, p = 0.025). Mean (SD) leak pressure (29 (8) vs 23 (11) cmH(2) O, p = 0.007) and expired tidal volume (PCV 17 cmH(2) O) (785 (198) vs 654 (91), p = 0.001) were significantly greater with the LMA Supreme than with the i-gel, respectively. More patients complained of pharyngolaryngeal pain with the LMA Supreme than with the i-gel (17/39 (44%) vs 8/41 (20%); p = 0.053). We found better first time success rate, fewer failures, and a better seal with the LMA Supreme compared with the i-gel, indicating that the LMA Supreme may be preferable for emergency airway use by novices.
