Comparison of Ease of I-gel Insertion With Two Different Techniques in Adults

The I-gel is used to provide the oxygenation and ventilation in anaesthetised patients. The inventor suggested insertion technique is called standard technique.

Standard I-gel insertion technique: I-gel insertion will be performed by firmly grasping the lubricated I-gel along the integral bite block site. I-gel cuff outlet will face towards the patient's chin and before insertion chin will be gently pressed down. The I-gel soft tip will be introduced into patient's mouth in a direction towards the hard palate. Then I-gel will be slide downwards and backwards along the hard palate with a continuous but gentle push until a definitive resistance is felt.

Modified jaw thrust technique: I-gel insertion will be performed by firmly grasping the lubricated I-gel along the integral bite block. I-gel cuff outlet will face towards the patient's chin and before insertion chin will be gently pressed down. The I-gel soft tip will be introduced into patient's mouth in a direction towards the hard palate and it slides gently into the oropharynx. I-gel will be left in oral cavity and both hands will be used to thrust the jaw by lifting the angle of mandible with little fingers and other fingers to stabilize the jaw then both thumbs will used to apply the balance force towards the final I-gel placement position by looking at the integral bite block mark at incisor teeth level.
