Three case studies where an i-gel® was used in an emergency situation are presented on the back of the authors’ previous knowledge that this SAD has ‘advantageous characteristics’, including quick insertion time, good seal pressures and high success rates. Cases were: a ‘violent’ but sedated male patient; a 69-year-old patient suffering a cerebral seizure; and an unconscious and intoxicated patient found at home. Regurgitation and aspiration were not seen in any case. Authors conclude that, alongside other pre-clinical emergency situations, i-gel® can be used in cases of sustained spontaneous breathing, and ‘could be considered for extended use outside the hospital’.

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.

This report details the use of an i-gel® to provide an airway for a 63-year-old male with severe subglottic swelling. Two prior attempts at insertion of a gum elastic bougie failed and facemask ventilation was ineffective. A well-known brand of laryngeal mask was inserted, but ventilation was impossible, so it was removed and replaced with an i-gel®. Subsequent intubation through the i-gel® was performed successfully with a flexible fibrescope.

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.
