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 supraglottic devices

Study summary:

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.


Inclusion Criteria: - Subjects that will require routine endotracheal intubation for general anesthesia as part of their surgery. - Age >18 years old. - Can provide informed consent. Exclusion Criteria: - 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 the airway. - Subjects that have an allergy to Propofol or eggs. - Subjects that have an allergy to rocuronium. - Subjects with a history of oropharyngeal or laryngeal surgery, or subjects undergoing oropharyngeal or laryngeal surgery. - Subjects with congenital or anatomical airway anomalies. - Subjects with anticipated reduced functional residual capacity as predicted by a body mass index ≥40. - Currently enrolled in another research study.
