70 children who were already scheduled for a cranial MRI scan took part in this study. The epiglottis was found to be in the bowl of the i-gel® in all patients, however the device still performed well.

In this study, the artefacts created during MRI by six supraglottic airways, the Classic LMA®, the ProSeal LMA®, the LMA Unique®, the LMA Supreme®, the Ambu® disposable laryngeal mask and the i-gel® were investigated. There were no artefacts with the i-gel® or Ambu® devices.

In this study, the i-gel® was used to ventilate 20 spontaneously breathing adult patients during anaesthesia. Insertion time, success rate, ability to insert a gastric tube and complications (including the presence of blood on the device) were recorded. The i-gel® was inserted on the first attempt in 19 of 20 patients and had a mean insertion time of 12 seconds. Gastric tube insertion was possible in all cases. Removal was uneventful for all patients and did not result in any complications. The authors believe that the i-gel® is a useful device for maintaining the patient airway during general anaesthesia.

This report details the case of a 47-year-old woman with subglottic stenosis. During preoperative screening she stated that there had been difficulty inserting an endotracheal tube during an earlier procedure. During anaesthesia, a size four i-gel® was inserted on the first attempt. A fibrescope was passed down the i-gel® and into the trachea, where subglottic stenosis could be seen. The i-gel® showed no signs of leaking and did not cause any trauma. The authors note that this is the first case report where an i-gel® has been used in a patient with subglottic stenosis, and state that preoperative tests should be carried out before choosing to use the device in this situation.

This case study describes the use of the i-gel® while the patient was in a prone position for surgery. A 45kg 16-year-old boy laid in a prone position with his head turned laterally. After induction of anaesthesia, a size three i-gel® was inserted on the first attempt. There were no adverse events either during or after surgery and the i-gel® was removed while the patient was still prone. Previous research has shown that the cLMA and ProSealTM airways can be inserted in the prone position, and i-gel®s have successfully ventilated prone patients who were turned over after insertion. However, this is the first reported case of i-gel® insertion while the patient is already prone. Routine use of this technique should only occur after further research has taken place.
