Summary

This study is designed to identify patients' features predictive of difficult endotracheal intubation using a flexible 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 with the direct laryngoscope. When direct laryngoscopy is difficult, early conversion to an alternative technique reduces the risk of airway compromise and associated morbidity. Many alternative 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 flexible fiberscope have not been developed. The purpose of this study is to identify patient morphometric or morphological characteristics, if any, that could predict difficult intubation when using the flexible fiberscope for perioperative tracheal intubation in an elective surgical population.

Conditions

• Intubation; Difficult

Interventions

Type	Name	Description
DEVICE	Flexible fiberscope	* 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 after silicon spray lubrication * Intubation will be performed with the flexible fiberscope with the patient in supine position with head and neck in neutral position * With the tip of the fiberscope in satisfactory position, the endotracheal tube will be advanced into the trachea. The scope will then be removed. * Accurate positioning of the endotracheal tube will be confirmed by capnography and lung auscultation.
