Duble Lumen Intubation

Not Applicable

Completed

• Conditions: Difficult Airway; Intubation;Difficult; Intubation; Difficult or Failed
• Interventions: Device: Standard double-lumen tube; Device: Double-Lumen Tube Vivasight-DL

• Registration Number: NCT03624439
• Lead Sponsor: Lazarski University

Brief Summary

Intrabronal intubation is one of the basic methods of airway protection during cardiac surgery. The use of double-lumen tubes in the implementation of a standard method based on macintosh laryngoscope may cause the prolongation of the procedure especially in the case of difficult airways. The aim of the study was to match the effectiveness of endotracheal intubation using a standard Macontosh laryngskop and a normal double-lumen tube versus the ETView DL tube.

Arm && Interventions

Group	Intervention	Description
Normal airway	Double-Lumen Tube Vivasight-DL	normal airway. the language has not been inflated. the instructor assessed the difficulty of intubation based on the Cormack - Lehane scale to the first degree
Normal airway	Standard double-lumen tube	normal airway. the language has not been inflated. the instructor assessed the difficulty of intubation based on the Cormack - Lehane scale to the first degree
Difficult airway	Double-Lumen Tube Vivasight-DL	dofficult airway. Difficult airways were obtained by means of language inflation using a simulator control panel, so as to obtain the degree of intubation difficulty assessed by an independent anesthesiologist to the third degree according to the Cormack-Lehane scale
Difficult airway	Standard double-lumen tube	dofficult airway. Difficult airways were obtained by means of language inflation using a simulator control panel, so as to obtain the degree of intubation difficulty assessed by an independent anesthesiologist to the third degree according to the Cormack-Lehane scale

Primary Outcome Measures

Name	Time	Method
intubation time	1 day	from taking of the intubation device to successful intubation

Secondary Outcome Measures

Name	Time	Method
time to visualize the glottis	1 day	time defined as the time from taking laryngoscope in hand until you obtain visualize the glottis
overall success rate	1 day	effectiveness measured during a maximum of three intubation attempts, confirmed by a single lung ventilation test
success of the first intubation trial	1 day	effectiveness of the first attempt of intubation by participants using four intubation devices
Cormack - Lehane grade	1 day	self-reported percentage the vocal cord visualization using the Cormack-Lehane grading (grade 1-4)
ease of use	1 day	To access subjective opinions about the difficulty of the each intubation method, participants were asked to give a rating on a visual analogue scale (VAS) with a score from 1 (extremely easy) to 100 (extremely difficult).
the degree of visibility of the glottis	1 day	The POGO score describes how much glottic opening is visible. A POGO score of 100% indicates visualization of the entire glottic opening from the anterior commissure of the vocal cords to the interarytenoid notch. A POGO score of 0% corresponds with no visualization of laryngeal structures.
