This study compared the i-gel® to the LMA Supreme® for the seal pressure during gynaecological laparoscopic surgery in the Trendelenburg position in 100 female patients. There was no difference in the oropharyngeal leak pressure with similar success rates for first time insertion and times to first capnograph trace. Both devices proved to be equally effective for gynaecological laparoscopic procedures.

This study compared the use of the i-gel®, LMA Supreme®, LMA Unique® and LMA ProSeal® supraglottic airways and bag-valve mask ventilation. 267 third-year medical students were given standardised training before using all devices in random order on an airway training manikin. The number of attempts needed to secure the device, time to successful ventilation, tidal volume, ease of use and incidence of gastric inflation were all recorded. After 12 months, participants used the devices again without further training. In both assessments, the i-gel® and the Supreme were the most likely to be inserted successfully on the first attempt. These devices were rated as the easiest to use. The i-gel® and bag-valve mask had the quickest time to successful ventilation, however the rate of gastric inflation was much higher with the bag-valve mask.

In this study, the performance of the LMA ProSeal® and i-gel® was compared during laparoscopic surgery. 60 patients were randomised into two groups and had the supraglottic airway inserted by an experienced anaesthesiologist (defined as >500 and >50 insertions for ProSealTM and i-gel® respectively.

In 25 patients, a bronchial blocker was inserted under direct vision with a fibreoptic bronchoscope through an i-gel®. The i-gel® provided a reliable, safe seal of the airway. The authors concluded that such a technique, for anaesthetists with the appropriate experience using a flexible fibreoptic scope, can facilitate safe, effective management of selected patients who are to undergo certain thoracic procedures.

This study compared the cLMA and i-gel® in 80 healthy adult patients. The patients were randomly assigned to two groups for insertion of one of the devices during surgery. Haemodynamic data, oxygen saturation and end-tidal CO2 were similar in both groups. Leak pressure was significantly higher with the i-gel®, which also had a shorter insertion time. Postoperative complications were generally comparable, however there was a higher incidence of nausea and vomiting in the cLMA group due to gastric insufflation.
