About

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.

Full 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.

Intubation with the Bonfils fiberscope

Experimental group

Description:

* Characteristics of patients will be assessed before induction of general anesthesia * Glottic visualization will be evaluated by direct laryngoscopy. * The endotracheal tube will be loaded onto the scope * Intubation will be performed with the Bonfils fiberscope with the patient in supine position with head and neck in neutral position * Bonfils fiberscope will be inserted from the right side of the patient's mouth, alongside the molars and advanced underneath the epiglottis. With the tip of the Bonfils in satisfactory position, the endotracheal tube will be advanced into the trachea using gentle rotary motions. The scope will then be removed. * Accurate positioning of the endotracheal tube will be confirmed by capnography and lung auscultation.
