Endoscopic thoracic sympathetic blockage (ETSB) is a commonly performed procedure for treating conditions like palmar hyperhidrosis (PH), facial flashing (FF), and hyperhidrosis, Raynaud’s syndrome, social phobia, and arrhythmia treatment.There are 2 main tracheal intubation methods in thoracic surgery—double lumen tube (DLT) and single lumen tube (SLT). DLT is a standard choice for open and endoscopic thoracic surgery. It allows separate ventilation of both lungs as well as rapid and effective deflation/inflation of the lung as necessary. The main advantage of DLT is the ability to provide an ample space for the surgeon to visualize the target area and perform the procedure in a comfortable manner. However, there are authors who have advocated the use of SLT for minor, short-duration video assisted thoracic surgeries like ETSB.Also new approaches like lung ultrasound develop to evaluate the performance o for DLT position in one lung ventilation. A recent meta-analysis reported better specificity with similar sensitivity for lung ultrasound when compared with clinical evaluation. And authors suggested ultrasound should be considered as a suitable imaging tool.High-frequency positive pressure ventilation (HFPPV) was first defined in 1967 to minimize the effect ventilator associated variables like cardiac output and mean arterial pressure and by lowering peak airway pressures.In our experience, the main factor impeding surgery is difficult lung deflation (DLD). In theory, DLT is the superior technique for surgery, but we planned to demonstrate that if HFPPV mode with SLT may provide similar benefits for uncomplicated cases. We aimed to compare anesthetic effectiveness of SLT for tracheal intubation with HFPPV versus classic DLT for tracheal intubation in ETSB surgery. Our secondary aim was to compare complications of the techniques.
