SupremeTM laryngeal mask airway vs. the i-gel® supraglottic airway in patients under general anaesthesia and mechanical ventilation with no neuromuscular block: a randomised 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.

Abstract text

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.
