Abstract

Background: The i-gel™ is a new device introduced recently. It differs from other supraglottic airway devices. It has a non-inflatable, gel-made cuff. Previously used devices, have some disadvantages which are claimed to be absent in i-gel™. In this study we aimed to compare the performance of the laryngeal mask airway (LMA)-Classic™ and i-gel™ during anesthesia in paralyzed patients.

Materials and methods: A total of 64 anaesthetized patients with paralysis were enrolled in a single-blind, randomized control trial to be intubated with one of the devices. We compared the device insertion parameters, some ventilatory parameters, and adverse effects after device insertion.

Results: Vital signs were not significantly different between groups. Regarding duration of insertion attempts, the difference between groups was significant (P < 0.05); while the number of insertion attempts was insignificant (P = 0.265). There was no significant difference between both groups regarding postoperative complications (cough, sore throat, and blood on the cuff) (P > 0.05). Airway leak was assessed in both groups and data showed no significant difference (P = 0.662). Additionally, end-tidal CO2 change regarding the baseline value was significantly different after 10 and 15 min of anesthesia (P < 0.05).

Conclusions: Successful insertion time was shorter significantly for i-gel™. As i-gel™ has easy application, it is advantageous to be used during cardiopulmonary resuscitation by non-anesthetists in which time is very important. We concluded that i-gel™ can be an alternative to LMA-Classic™ for controlled ventilation during anesthesia as it is easier to be placed.
