i-gel® from Intersurgical: clinical evidence listing

Cook T, Howes B. CEACCP 2010; 11 (2): 56-61

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.
