The investigators plan to conduct a randomized trial comparing the efficacy of intubating
the tracheal using an Aintree intubation catheter through either the LMA-S or I-gel
With the proposal, the investigators are comparing two different types of supraglottic
devices. One is the LMA Supreme (laryngeal mask airway) and the other is the I-gel. The
study is designed to use the supraglottic airway device as an adjunct to tracheal
intubation, not as the definitive airway. The investigators will be utilizing the Aintree
intubation catheter over the fiberoptic bronchoscope in an effort to secure the airway. This
technique has been well described in the literature and has been proven effective and safe.

part of their surgery.
- Age >18 years old.
- Can provide informed consent.
- Subjects that require rapid sequence induction for endotracheal intubation; i.e.,
parturients, or any subject that is at high risk for aspirating gastric contents into
