Force and Pressure Distribution Using Macintosh and GlideScope Laryngoscopes in Normal Airway: an in Vivo Study

Intervención / Tratamiento
Descripción detallada
Forces applied on soft upper tissues by different laryngoscope blades during direct laryngoscopy and intubation are considered to be major stimuli to cause serious damages to the patients, such as local injures to incisors, larynx and spinal column, or hemodynamic changes in heart rate and/or blood pressure due to autonomic nervous system stimulation.
In order to reduce risk of such injures, indirect videolaryngoscopy provides the advantage of an easier laryngeal visualization with less need for the mouth-pharyngeal-laryngeal axes alignment, thereby reducing the detrimental effects above mentioned.
The aim of this study is to measure the minimal force exertion to achieve not only glottis view but also a successful intubation, comparing GlideScope and Macintosh laryngoscope, in patients with normal airway conditions. Furthermore, The investigators measured the following parameters: pressure distribution upon the blade; time required to visualize the glottis; time required to complete oro-tracheal intubation.

Comparador activo: Direct laryngoscope
Includes cases in which the forces applied by Macintosh direct laryngoscope onto soft tissue of the pharynx during glottis visualization and intubation were measured.
|
Force and pressure distribution applied by direct or indirect laryngoscope during glottis visualization and intubation were measured using film pressure transducers.
|

Comparador activo: Indirect laryngoscope
Includes cases in which the forces applied by GlideScope indirect laryngoscope onto soft tissue of the pharynx during glottis visualization and intubation were measured.
|
Force and pressure distribution applied by direct or indirect laryngoscope during glottis visualization and intubation were measured using film pressure transducers.

Force Applied and Pressure Distribution Upon the Blade of Laryngoscopes During Tracheal Intubation.
Periodo de tiempo: Force measurement is referred to an average of 45 seconds in patients scheduled to undergo elective surgery under general anaesthesia
|
The pressure distribution exerted upon the tissues by the blade was measured (in Newton)through pressure film transducers put on the blade of both direct and indirect laryngoscopes, in order to compare the two devices.

Force measurement is referred to an average of 45 seconds in patients scheduled to undergo elective surgery under general anaesthesia

Time Required to Visualize the Glottis and Complete Oro-tracheal Intubation
Periodo de tiempo: On average 20 seconds
|
Since the time needed for laryngoscopy and intubation could represent one of the major contributors to the stress response during these procedures, times to achieve the glottis visualization and to perform the entire intubation were recorded.
|
On average 20 seconds
