Intubation, Bonfils fiberscope
Brief summary
This study is designed to identify patients' features predictive of successful intubation using the Bonfils fiberscope. Our hypothesis is that some patients' characteristics are predictors of successful intubation with the Bonfils fiberscope.
Detailed description
Endotracheal intubation is an important act in the practice of anesthesiology. Direct laryngoscopy is the most commonly used technique to accomplish this task. Airway characteristics predicting difficult intubation with direct laryngoscopy are well defined. Physical findings, such as Mallampati classification or measurements of the thyromental distance, mouth opening, and neck extension have been validated to help anticipate difficult situations. When direct laryngoscopy is strenuous, early conversion to an alternative technique might reduce the risk of airway compromise and associated morbidity. Many intubation devices are now available and part of the anesthesiologist's task is to select the alternative approach best suited to each patient's specific features. Despite its use for both elective and unexpectedly difficult intubation, predictive criteria for successful airway management with the Bonfils fiberscope have not been proposed. The purpose of this study is to identify patients' features, if any, that could predict successful intubation when using the Bonfils fiberscope for perioperative orotracheal intubation in an elective surgical population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Morphologic and morphometric predictors of successful tracheal intubation with the Bonfils fiberscope | Patients will be followed from induction of anesthesia until the end of intubation, an average of 10 minutes | This study will correlate patients' morphometric and morphologic characteristics with the number of attempts and time needed for intubation using the Bonfils fiberscope. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to successful intubation | Patients will be followed from induction of anesthesia until the end of intubation, an average of 10 minutes | — |
| Number of attempts to successful intubation | Patients will be followed from induction of anesthesia until the end of intubation, an average of 10 minutes | — |
| Score on the Intubation Difficulty Scale | Patients will be followed from induction of anesthesia until the end of intubation, an average of 10 minutes | To calculate the Intubation Difficulty Score the following variables will be collected: number of attempts, number of operators, necessity to use an alternative intubation technique, glottic visualization and effort needed to obtain optimal view of the glottis, necessity of external laryngeal pressure and vocal cords position during intubation. |
