We, therefore conducted a randomized cross over study to evaluate the usefulness of this new device use by experienced anesthesiologists in several airway manikin scenarios. We hypothesized that in the hands of experienced anesthesiologists the new Flexible Tip Bougie catheter would perform comparably to the standard bougie catheter) in the normal airway scenario. In the difficult airway (both tongue edema, manual in-line stabilization, or cervical collar stabilization), we hypothesized that the new Flexible Tip Bougie catheter would prove superior to the standard Bougie stylet.

intubation with the standard Bougie stylet for difficult intubation and endotracheal tube 7.0 internal diameter
intubation with The new Flexible Tip Bougie catheter and endotracheal tube 7.0 internal diameter
Lazarski University
Warsaw, Masovia, Poland
time to intubation
time from pick up device to the final placement tube in trachea
Time frame: 1 day
success of intubation
A failed intubation attempt was defined as an attempt in which the trachea was not intubated, or which required more than 120 seconds to perform
Time frame: 1 day
Number of optimalization maneuvers
the number of optimization maneuvers required (re-adjustment of head position, second assistant) to aid endotracheal intubation.
Time frame: 1 day
Ease of use
self-reported percentage the vocal cord visualization. A 100% score is a extremely difficult procedure. A Ease of use score of 1% means that procedure is extremely easy
Time frame: 1 day
Dental compression
An independent observer scored the severity of dental compressions, which was calculated based on the number of audible teeth clicks (0; 1; ≥2) with the Laerdal airway trainer, and based on a grading of pressure of the teeth (none = 0; mild = 1; moderate/serve ≥2) on the Simman®3G simulator. At the end of each scenario, each participant scored the ease of use of each intubation method on a visual analogue scale (VAS; from 0=Extremely Easy to 100=Extremely Difficult).
