i-gel® from Intersurgical: clinical evidence listing

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

Randomized crossover comparison of the laryngeal mask airway classic with i-gel® laryngeal mask airway in the management of difficult airway in post burn neck contracture patients

Singh J, Yadav MK, Marahatta SB, Shrestha BL. Indian J Anaesth 2012; 56(4): 348-52

Prospective, crossover, randomised trial of i-gel® against cLMA on 48 post-burn neck contracture patients with reduced neck movement and mouth opening. Primary outcome was overall success rate, with other measurements taken in time to ventilation, leak pressure, fibreoptic view and visualisation of square wave pattern. Success rate for i-gel® was 91.7%, against 79.2% for cLMA. i-gel® outperformed cLMA in all measurements. Authors conclude their study has ‘better clinical performance in the difficult airway management of the airway in the post burn contracture of the neck’.

A preliminary study of i-gel®: a new supraglottic airway device

Kannaujia A, Srivastava U, Saraswat N, Mishra A, Kumar A, Saxena S. Indian J Anaesth 2009; 53(1): 52-56

50 patients had the i-gel® inserted for ventilation during surgery. The number of insertion attempts, insertion time, manipulations required for an effective airway and seal pressure were recorded. Gastric tube placement and adverse events were also noted where they occurred. Before removal of the device, stability was tested by measuring the expiratory tidal volume with the patient’s head in standard, rotated, chin lift and no-pillow positions. Success rate was 90% at the first attempt and 100% at the second. Median insertion time was 11 seconds. Insertion depth was increased in four patients and a jaw thrust was required in two more. All gastric tubes were placed successfully. Mild cough or postoperative sore throat was seen in a total of four patients. Seal pressure was approximately 20cm H2O. The i-gel® was also found to be stable during head and neck movement.

Comparison of clinical performance of i-gel® with LMA Proseal® in elective surgeries

Singh I, Gupta M, Tandon M. Indian J Anaesth 2009; 53(3): 302-305

This clinical investigation into performance of i-gel® compared to another supraglottic airway with gastric access, concluded that i-gel® was easier to insert, required fewer attempts at insertion, had easier gastric tube placement and was less traumatic than the other device tested. Sixty patients were randomly assigned into two groups: Group 1 (n=30) for i-gel® and Group P (n=30). Assessment was made of sealing pressure, ease of insertion, success rate of insertion, ease of gastric tube placement, airway trauma by post operative blood staining of the device, tongue, lip and dental trauma, hoarseness, regurgitation/aspiration and cost effectiveness.
