The use of i-gel® extraglottic airway during percutaneous dilatational tracheostomy: a case series

Corso RM, Piraccini E, Agnoletti V, Baccanelli M, Coffa A, Gambale G. Minerva Anaestesiol 2011; 77(8): 852-3

The i-gel® was used in eight patients for tracheostomy. Patients were extubated and the ET tube was replaced with the i-gel®. A percutaneous tracheostomy kit was then advanced to the second tracheal ring and the procedure was performed. Arterial pressure, PaO2/FiO2, minute ventilation and airway pressure were measured before, during and after tracheostomy. There were no significant differences in ventilatory and haemodynamic parameters. Use of the i-gel® was successful in seven of eight patients. The i-gel® provided better views of the glottis compared to the cLMA and ventilation was comparable to the ET tube. Large trials must take place to determine whether a one in eight failure rate remains.

The use of an i-gel® supraglottic airway for the airway management of a patient with subglottic stenosis: a case report

Donaldson W, Michalek P. Minerva Anestesiol 2010; 76(5): 369-372

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.

Insertion of the i-gel® airway in prone position

Taxak S, Gopinath A. Minerva Anestesiol 2010; 76(5): 381

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.
