This letter is a response to Kushakovsky and Ahmad (2009 - see above) regarding the performance of the LMA Supreme®, LMA ProSealTM and i-gel® devices. The letter states that the i-gel® and ProSeal® have both been shown to vent gastric contents when they have good placement and oesophageal seal, but that this has not been studied in the LMA Supreme®. Only small studies comparing the LMA Supreme®, ProSeal and i-gel® are available, although these generally show comparable performance. The authors recommend further research with larger study populations.
