This study will compare the Macintosh laryngoscope with the Pentax. The Pentax AWS is a novel airway management device that is designed to facilitate laryngoscopy and endotracheal intubation.
100 obese patients (BMI 30 to 50) requiring orotracheal intubation for elective surgery will be randomly allocated to intubation with either a conventional Macintosh laryngoscope or with the Pentax AWS. Our study hypothesis is that use of Pentax AWS will make tracheal intubation easier to perform in the obese surgical patient (BMI 30 to 50), as evidenced by the time to complete the intubation process as well as an "Ease of Use" visual analog score (VAS) measure.

Cleveland Clinic
Cleveland, Ohio, United States
Time to Intubation
time between sufficient muscle relaxant and placement of intubation tube
Time frame: time between sufficient muscle relaxant and placement of intubation tube, up to 100 seconds
Ease of Intubation
Ease of intubation was recorded by the operator immediately after intubation on a 100 mm visual analog scale (VAS). The score ranges from 0 to 100. A higher score indicates more difficulty in intubation
Time frame: From the start of intubation until 24 hours after surgery
Successful Intubation on the First Attempt
The count number of successful intubation on the first attempt
Time frame: From the start of intubation until 24 hours after surgery
The Number of Patients With Different Number of Intubation Attempts
We summarized the number of patients with one, two or three intubation attempts.
Time frame: From the start of intubation until 24 hours after surgery
The Number of Patients With Bleeding
Time frame: From the start of intubation until 24 hours after surgery
