title: Comparison of i-gel™ and laryngeal mask airway in anesthetized paralyzed patients.
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.
  
  
  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.
