Interventions

Name	Type	Description	Arm Group Labels	Other Names
Determination of tube position by ultrasound.	Device	After placement of the left sided double lumen endotracheal tube, ventilation of both lungs will be verified by ultrasound (Sonoscape S6®). The ultrasound probe will be placed between the 2nd and 3rd intercostal space at the level of the midclavicular line parallel to the line. The probe will be slightly moved or tilted until the pleural line is identified. If lung sliding is identified then the ventilation of the lung will be considered adequate. The same procedure will be repeated for each lung alone, after lung separation is applied. Verification of the ultrasound findings will be performed by bronchoscopy (Pentax®). The depth of the tube will be adjusted according to the bronchoscopy findings until correct positioning is established.

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Correct position of the tube (yes/no).	The anesthesiologist who will place the left-sided double lumen tube will determine if the position of the tube is correct according to the ultrasound or clinical findings.	Within an average of 5 minutes after the placement of the double lumen tube
Correct position of the tube by bronchoscopy (yes/no).	After the assessment of the tube's position, a second anesthesiologist will verify the position of the tube by bronchoscopy.	Within an average of 10 minutes after the placement of the double lumen tube.

Secondary Outcomes

Measure	Description	Time Frame
Time needed	The total time passed from the beginning of laryngoscopy until the final verification of the tube's position.	Within an average of 10 minutes after the placement of the double lumen tube.
