About

This study evaluates the efficiency of the rigid tube for laryngoscopy for tracheal intubation in patients with presumed difficult airway and compare the classical laryngoscopy and this method in matter of glottis visualisation and tracheal intubation.

Full description

The rigid tube for laryngoscopy is a 15 to 30 cm long metallic tube with a bevel end and a diameter of 0.5-2.0 cm , an instrument used to inspect the larynx and surrounding areas. It resembles a rigid bronchoscope but it is shorter. When in use, it has to be attached to a light source.

The hypothesis of the study stands that the rigid tube for laryngoscopy could be more efficient in tracheal intubation for difficult airway patients when the classical intubation with a curved blade laryngoscope is unsatisfactory.

The retromolar approach in both sides together with bougie(intubating tube introducer) intubation is the technique of intubation used in this study.

Description:

Tracheal intubation with the rigid tube for laryngoscopy for patients with difficult airway. Prior the use of rigid tube for laryngoscopy, a classical laryngoscopy with a McIntosh laryngoscope will be performed.

Treatment:

Device: rigid tube for laryngoscopy

Device: classical laryngoscopy
