Brief Summary
This study aims to evaluate the utility of a video assisted device for intubation (placement of a breathing tube) during surgery. This study specifically aims to compare a video assisted intubation with the CMAC laryngoscope to conventional devices in the setting of intubations predicted to be difficult.

Outcome Measures
Primary Outcomes (1)
Measure of Intubation Success
Success was measured by confirmed tracheal tube placement with one attempt. Any removal of the laryngoscope blade constituted a failure
During each intubation in a 14 month period
Secondary Outcomes (5)
Intubation Time
During laryngoscopy procedure
Number of Participants Intubated With a Rescue Device
1 year
Number of Participants With Complications
1 year
Number of Participants With a Laryngeal View Grade of 1 or 2 vs. 3 or 4.
1 year
Number of Particpants Requiring Adjuncts to Assist Intubation
1 year
Study Arms (2)
CMAC Video laryngoscope
ACTIVE COMPARATORSubjects will have their intubation attempted first with the CMAC video laryngoscope
Macintosh blade
ACTIVE COMPARATORPatients will have their first intubation attempted utilizing the conventional Macintosh design laryngoscope blade
Interventions
Intubation utilizing the assistance of video enhancement
Patients will be intubated utilizing either a Macintosh 3 or Macintosh 4 designed blade
Eligibility Criteria
You may qualify if:
- Adult patients presenting for elective surgery who are fasted and who have one of the following difficult airway predictors:
- mallampati classification 3
- mallampati classification 4
- Reduced mouth opening (\<3cm)
- reduced cervical motion
- history of previous difficult intubation or multiple laryngoscopy attempts
You may not qualify if:
- Patients less than 18 years old, patients who are not fasted (\>6 hrs. NPO)
- Patients who have contraindications to the administration of neuromuscular blocking drugs
- Patients who have a documented history of intubation on first attempt with C-L grade 1 laryngeal view
- Patients who are deemed to difficult and dangerous to anesthetize without first securing an airway.
