In the DLT group, the lung on the side to be treated was distinguished from the ventilator and extinguished and single lung ventilation was performed with the other lung.

In the SLT group, after thoracoscopic input, the anesthetist was in contact with the surgeon and his lung pressures were reduced manually until the lowest pressure, where the surgeon's vision was optimal.

we aimed to compare anesthetic outcomes of single lumen intubation with Heart-Lung Machine mode ventilation versus double lumen intubation study in endoscopic thoracic sympathetic blockade
