Right Side Bronchial Blocker in Video-assisted Thoracoscopic Surgery

After general anesthesia, an 8.0 mm internal-diameter single-lumen endotracheal tube was
inserted orally. An independent Coopdech bronchial blocker, which has a formed-curvature
near the catheter tip, was directly inserted through the single-lumen endotracheal tube into
right main bronchus. Chest inspection, auscultation, fiberoptic bronchoscopy confirmation,
if necessary, by visualizing the blocker cuff located at right main bronchus just below the
carina was performed firstly. After placing patients in left decubitus position, the
position of BB was reconfirmed by auscultation firstly; then complete collapse of the right
upper lobe was adjust, if necessary and reconfirmed on the video of thoracoscopy by both
surgeon and anesthesiologists. The depth of BB and the need of fiberoptic bronchoscope were
recorded. All the patients were extubated in operation room after completion of operation
with optimal analgesia. Data collected included; age, sex, body height and weight and the
depth of right-sided BB from incisor was then recorded.
