NCT02857504

Brief Summary

One lung ventilation (OLV) has become a standard procedure for the vast majority of interventions in pulmonary surgery. It is used in both techniques: thoracotomy and videothoracoscopy (VATS). OLV can be provided by double lumen tube (DLT) with or without the hook. In our study the investigators want to find out if there is any advantage with one or another.

Outcome Measures

Primary Outcomes (1)

  • intubation

    The time needed for tube insertion (time from seeing the vocal cords to final position of the tube) was measured.

    intraoperative

Study Arms (2)

double lumen tube with a hook

OTHER

The tube with the hook (after passing the bronchial cuff trough the vocal cords) was rotated for 180 degrees to the left and removed the stylet and when the hook passed the vocal cords, the tube was rotated for 90 degrees back to the right and push it into the bronchus. Following formula was used for the right depth (height (cm)/10 + 12 (cm)) of the tube without the hook. The tube with hook was inserted into the bronchus so that hook was placed on the carina and stopped.

Device: double lumen tube with a hook

double lumen tube without a hook

OTHER

Tube without the hook was inserted with the following technique: after the bronchial cuff was passed the vocal cords, the stylet was removed and the tube was rotated 90 st towards left.
