Ultrasound for Double Lumen Endotracheal Tube

Not Applicable

Terminated

• Conditions: Lung Ultrasound
• Interventions: Other: Determination of tube position by auscultation.; Device: Determination of tube position by ultrasound.

• Registration Number: NCT02556853
• Lead Sponsor: 424 General Military Hospital

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

Arm && Interventions

Group	Intervention	Description
Clinical	Determination of tube position by auscultation.	Determination of correct placement of the double lumen tube by clinical examination.
Ultrasound	Determination of tube position by ultrasound.	Determination of correct placement of the double lumen tube by lung ultrasound.

Primary Outcome Measures

Name	Time	Method
Correct position of the tube by bronchoscopy (yes/no).	Within an average of 10 minutes after the placement of the double lumen tube.	After the assessment of the tube's position, a second anesthesiologist will verify the position of the tube by bronchoscopy.
Correct position of the tube (yes/no).	Within an average of 5 minutes after the placement of the double lumen tube	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.

Secondary Outcome Measures

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