Comparison of the New Flexible Tip Bougie Catheter and Standard Bougie Stylet for Tracheal Intubation by Anesthesiologists in Different Difficult Airway Scenarios: a Randomized Crossover Trial

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.
