About

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.

Full description

Patients will be specifically screened for predictors by history and physical exam of potential airway difficulty. The role of video laryngoscopy in airways predicted to be difficult is poorly defined. This study aims to recognize if video laryngoscopy is more useful than conventional laryngoscopy as a first attempt for those with anticipated difficulty.

Enrollment

Ages

18 to 99 years old

Volunteers

No Healthy Volunteers

Inclusion criteria

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

Exclusion criteria

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.
