I-gel Supraglottic Device
The I-gel is an alternative supraglottic device made from thermoplastic elastomer which provides the seal over the airway versus an inflatable cuff.
I-gel supraglottic device: The fiberscope (with the Aintree loaded on top of it) will be advanced through the supraglottic device into the trachea. Next, the supraglottic device will be removed and the endotracheal tube will be advanced into the airway over the Aintree airway intubation catheter. Finally, the Aintree catheter is removed and the endotracheal tube will be left in the airway.

LMA-Supreme Supraglottic Device
The LMA-Supreme is a single-use disposable supraglottic airway that utilizes an inflatable cuff
LMA-Supreme supraglottic device: The fiberscope (with the Aintree loaded on top of it) will be advanced through the supraglottic device into the trachea. Next, the supraglottic device will be removed and the endotracheal tube will be advanced into the airway over the Aintree airway intubation catheter. Finally, the Aintree catheter is removed and the endotracheal tube will be left in the airway.
