i-gel® from Intersurgical: clinical evidence listing

Mukadder S, Zekine B, Erdogan KG, Ulku O, Muharrem U, Saim Y, Mahmut D. ScientificWorldJournal. 2015;2015:634320

105 patients were randomly distributed between the three device groups. Initial leak pressure, insertion time, ease of placement and airway morbidity results all favoured the i-gel.

After induction of anaesthesia and device insertion, head position was ranomly changed from neutral to flexion, extension and lateral rotation. Leak pressure, fibreoptic view and ventilation scores were among the results measured. Effective ventilation can be performed with both devices, but 'extreme precaution' should be taken in flexion position in ProSeal.

Patients were evenly distributed between the two device groups, with ease and number of insertions, insertion speed and leak pressure amongst outcomes measured. SLIPA appeared to be quicker to insert, however blood staining incidence was higher.

Patients were randomised between the two groups, with device inserted in supine position. Insertion time and attempts, airway peak pressure and complications were among results measured. i-gel provided a higher airway seal pressure in the prone position and both devices recorded low complication rates.

Case report of failed fibreoptic intubation and videolaryngoscope on a 25-year-old male with TCS who had undergone emergency abdominal surgery. i-gel was used instead and was inserted on first attempt and the airway successully maintained.
