This review article looks at the evidence for the efficacy of supraglottic airway devices. The authors use the cLMA as a standard for comparison. The ProSealTM, i-gel®, LMA Supreme® and LTS Mk. IITM are all discussed. Most of the i-gel® literature is positive and shows a high level of successful use. However, more clinical trials need to take place in order to confirm these findings.
