i-gel® from Intersurgical: clinical evidence listing

A comprehensive list of all known published clinical evidence on the device

Application of PEEP using the i-gel during volume-controlled ventilation in anesthetized, paralyzed patients.

Kim YB, Chang YJ, Jung WS, Byen SH, Jo YY. J Anesth. 2013 Dec;27(6):827-31

After placement of an i-gel device in 40 patients, 20 were ventilated without PEEP while the other half received 5cmH20. Incidences of significent leaks and leak volumes were similar in both groups.

Use of extraglottic airways in patients undergoing ambulatory laparoscopic surgery without the need for tracheal intubation

Suhitharan T, Teoh WH. Saudi J Anaesth. 2013 Oct;7(4):436-41

Ransomised control trial comparing LMA Supreme with i-gel in 70 patients, with leak pressure, insertion success rates and leak fractions among the outcomes measured. While no post-operative complications were reported with i-gel, three patients suffered mild sore throat and one had mucosal injury in the Supreme group. i-gel had a higher but 'clinically inconsequential' leak fraction.

Performance of the i-gel™ during pre-hospital cardiopulmonary resuscitation

Häske D, Schempf B, Gaier G, Niederberger C. Resuscitation 2013; 84(9): 1229-32

This observational study of i-gel® use during CPR assessed ease of insertion, ventilation quality, leak and whether ventilation was possible without chest compression interruption. Insertions were attempted by 63 paramedics and seven emergency physicians in pre-hospital CPR, with an overall 90% first-attempt insertion success rate. Insertion was reported as easy in 80% of cases, with the same figure representing cases with no leak recorded. In 74% of cases, continuous chest compression was still possible. The authors say that, ‘the i-gel is an easy supraglottic device to insert and enables adequate ventilation during CPR’.

Supraglottic airway devices during neonatal resuscitation: An historical perspective, systematic review and meta-analysis of available clinical trials

Schmolzer GM, Agarwal M, Kamlin CO, Davis PG. Resuscitation 2013; 84(6): 722-30

Review of available literature on the use of supraglottic airway devices during neonatal resuscitation. Current evidence suggests that resuscitation with a laryngeal mask is a ‘feasible and safe alternative to mask ventilation in infants’, however further randomised controlled trials are needed.
