Standard Versus Flexible Tip Bougie for Videolaryngoscopy

Status Recruiting

Clinical Trial Summary

This study aims to compare the flexible tip bougie with standard bougie for tracheal intubation using non channelled, acute angled video laryngoscope using modified intubation difficulty scale score as primary outcome.

Clinical Trial Description

Videolaryngoscopes are devices which aid successful intubation of the trachea. Unlike standard (direct) laryngoscopes, they include a camera at the tip of the blade and display unit to provide an indirect view of the vocal cords (glottis). They are now routinely used for both standard and anticipated difficult tracheal intubation, and are recommended for difficult intubation in UK national guidelines. Some videolaryngsocopes have a channel as a guide to help with placement of a tracheal tube and some are without a channel. The non-channelled videolaryngoscopes with acute-angled blades require a bougie or stylet to facilitate the passage of a tracheal tube through the glottis into the trachea. One problem commonly encountered when using a standard bougie, is the tip of the bougie abutting on the anterior part of glottis and entrance to the windpipe (trachea) and not advancing further into the trachea. This is known as anterior impingement. This can increase the likelihood of repeated intubation attempts, failed intubation and airway trauma. C-Mac is a commonly used non-channelled videolaryngoscope and has been shown to have high first attempt success rate as compared to other videolaryngoscopes, however, the acute angled D-blade requires a bougie to facilitate tracheal intubation. The recently introduced flexible tip bougie is likely to overcome the problem of anterior impingement, due to the ability to flex the tip in the posterior direction once the tip enters the glottis. Comparing the efficacy of these devices could help inform anaesthetists' decisions in the future when faced with a potentially difficult airway. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
