Comparing the i-gel to First- and Second-Generation LMAs

Rates of successful insertion did not differ, but the i-gel and second-generation LMAs performed best.

Researchers compared performance of the i-gel and the laryngeal mask airway (LMA) in a meta-analysis of randomized, controlled trials involving patients undergoing elective surgery. The i-gel was compared to a first-generation LMA (Classic, La Premiere, AuraOnce, Solus, Unique) in 18 trials and to a second-generation LMA (ProSeal, Supreme) in 16.

Rates of successful insertion did not differ among groups. The i-gel was quicker to insert than first-generation but not second-generation LMAs (mean difference of –3.6 and +0.74 seconds, respectively). Sore throat was significantly less frequent in the i-gel than in the LMA groups. Leak pressure was statistically lower with first-generation LMAs than with the i-gel, and lower with the i-gel than wi…
