i-gel® from Intersurgical: clinical evidence listing

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

Supreme laryngeal mask airway vs the I-gel supraglottic airway in patients under general anesthesia and mechanical ventilation with no neuromuscular block: a randomized clinical trial

Fernández Díez A, Prez Villafane A, Bermejo González JC, Marcos Vidal JM. Rev Esp Anestesiol Reanim 2009; 56: 474- 478

In this study, 85 patients were randomised into two groups for ventilation via LMA Supreme® or i-gel® supraglottic airways. Ease of insertion, seal pressure, ventilatory parameters and insertion of a gastric tube were all recorded. Both devices were easy to insert, with the SupremeTM and i-gel® being inserted on the first attempt in 95.2 and 86% of cases respectively. Performance was generally comparable.

A PROSPECTIVE RANDOMIZED COMPARATIVE STUDY TO COMPARE THE HEMODYNAMIC AND METABOLIC STRESS RESPONE DUE TO ENDOTRACHEAL INTUBATION AND I-GEL USAGE DURING LAPAROSCOPIC CHOLECYSTECTOMY

Biswas S, Mandal S, Mitra T, De Ray S, Chanda R, Sur D.

64 patients were randomly assigned to either the i-gel or ETT group, with venous blood samples taken after induction and 20 minutes following. Authors conclude i-gel is 'a suitable, effective and safe' alternative to ETT in this scenario.

Supraglottic airways and pulmonary aspiration: the role of the drain tube

Drolet P. Can J Anesth 2009; 56(10): 715-720

This article discusses the gastric channel or drain tube as a safety feature provided in supraglottic airways. Although pulmonary aspiration of gastric contents is a relatively rare event, it can be made rarer with the use of devices that include a gastric channel, particularly if they are inserted using a bougie. i-gel® is discussed.

A comparison of the i-gel® with the LMA-Unique® in non-paralysed anaesthetised adult patients

Francksen H, Renner J, Hanss R, Scholz J, Doerges V, Bein B. Anaesthesia 2009; 64(10): 1118-1124

In this study, 80 patients were randomly allocated to either i-gel® or LMA-Unique® insertion before minor surgery. Ventilation, insertion time, airway pressure, leak pressure and postoperative sore throat were all measured. Results were similar for all parameters other than airway leak pressure, which was significantly higher in the i-gel® (mean pressure 29cm H2O compared to 18cm H2O). Both devices are acceptable for use in securing an airway, however the increased leak pressure is an advantage for the i-gel®.
