Study Groups

Ultrasound
Determination of correct placement of the double lumen tube by lung ultrasound.
Determination of tube position by ultrasound.
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.
Clinical
Determination of correct placement of the double lumen tube by clinical examination.
Determination of tube position by auscultation.
After placement of the left sided double lumen endotracheal tube, ventilation of both lungs will be verified by auscultation of the upper lung fields. 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.
