NCT02556853

Brief Summary

The patients will be allocated to 2 groups: the ultrasound group and the clinical group. The correct position of the double lumen tube will be determined by ultrasound (Sonoscape S6®) for the patients of the one group (group U) and by clinical examination for the patients of the other group (group C). The correct placement will be verified by bronchoscopy (Pentax®). The two methods will be compared in terms of sensitivity and specificity. The main purpose of the study is to determine if the ultrasound can be used for determination of the correct placement of the left sided double lumen endotracheal tube

Outcome Measures

Primary Outcomes (2)

  • 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 (1)

  • Time needed

    Within an average of 10 minutes after the placement of the double lumen tube.

Study Arms (2)

Ultrasound

EXPERIMENTAL

Determination of correct placement of the double lumen tube by lung ultrasound.

Device: Determination of tube position by ultrasound.

Clinical

ACTIVE COMPARATOR

Determination of correct placement of the double lumen tube by clinical examination.

Other: Determination of tube position by auscultation.

Interventions

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.

Ultrasound

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.
