Gum Elastic Bougie vs The Frova Airway Intubating Catheter when using the Glidescope for difficult intubation

Randomised controlled trial of Portex tracheal tube and Frova intubating introducers used with the GlideScope videolaryngoscope in simulated difficult intubation on intubation time (s) and success rate (%) in patients with American Society of Anaesthesiologists (ASA) grade 1 or 2 physical status who required tracheal intubation for elective surgery.

Brief summary

Background: A ‘bougie’ may be less traumatic than the GlideScope-specific intubating stylet during videolaryngoscopy-guided intubation, but no comparative studies of bougies have been performed. Objective: To compare the Portex tracheal tube introducer (PTTI) and Frova intubating introducer (FII) used with the GlideScope videolaryngoscope in simulated difficult intubation.

Interventions

Intervention: After standardised intravenous induction, cervical manual in-line stabilisation was performed to increase intubation difficulty. Intubation was performed under GlideScope videolaryngoscopy assisted by either the PTTI or the FII.
