i-gel® from Intersurgical: clinical evidence listing

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

Are supraglottic airways a safe alternative to tracheal intubation for laparoscopic surgery?

Thompson J, O’Neill S. Br J Hosp Med 2008; 69(5): 303

This review article compares supraglottic airways to tracheal intubation for laparoscopic surgery. Evidence gathered so far indicates that supraglottic airways such as the i-gel® produce adequate ventilation and pressures with a reduced risk of complications such as aspiration. The authors state that further investigation should take place to determine whether these devices can be used in obese patients during laparoscopic procedures.

Effect of chest compressions on the time taken to insert airway devices in a manikin

Gatward JJ, Thomas MJC, Nolan JP, Cook TM. Br J Anaesth 2008; 100(3): 351-356

In this study, 40 volunteer doctors regularly involved in CPR, were timed inserting four different airway devices, including i-gel® and a tracheal tube, with and without stopping chest compressions. Comparison of the speed of insertion of the different devices during CPR allowed ranking of the devices. The i-gel® was inserted approximately 50% faster than the other devices tested.

Fibreoptic intubation through an i-gel® supraglottic airway in two patients with predicted difficult airway and intellectual disability

Michalek P, Hodgkinson P, Donaldson W. Anesth Analg 2008; 106(5): 1501-1504

This case study describes successful fibreoptic guided tracheal intubation through the i-gel® in two uncooperative adult patients with learning disability and predicted difficult airway. The i-gel® maintained the airway immediately after induction, allowing oxygenation and ventilation. Fibreoptic identification of the laryngeal inlet was successful on the first attempt and a tracheal tube inserted into the trachea, without complication, in both patients.

Nerve damage following the use of an i-gel® supraglottic airway device

Theron AD, Loyden C. Anaesthesia 2008; 63(4): 441-442

This article describes a post-operative complication after i-gel® use. The patient was successfully ventilated with a size four i-gel®, which was in line with the recommendation for the patient’s weight (85kg). After surgery, the patient reported numbness in the lower lip. An examination shows swelling and an ulcer on the inside of the lip. There are two possible explanations for this injury – the patient’s lip may have been caught in the tape used to secure the i-gel® or it may have been caught in between the i-gel® and the patient’s teeth. The authors warn that this could occur with any airway device, but that extra care should be taken with the i-gel® due to the bulkier design.

A new single use supraglottic airway with a non-inflatable cuff and an esophageal vent: An observational study of the i-gel®

Richez B, Saltel L, Banchereau F, Torrielli R, Cros AM. Anesth Analg. 2008; 106(4): 1137-9

This study on 71 ASA I-II women scheduled for gynaecological surgery, reported a 97% insertion success rate with i-gel®. Mean seal pressure was 30cm H2O. A gastric tube was inserted in 100% of cases. Only one case of coughing and sore throat occurred. The authors concluded that ‘the i-gel® is a reliable, easily inserted airway device that provides an adequate seal with a low morbidity rate.’
