ABSTRACT: Background: Thoracic surgery requires lung isolation techniques, which are typically achieved using a double-lumen bronchial tube or a single-lumen tube combined with a bronchial blocker. Double-lumen bronchial tubes have a larger diameter and may cause more significant intubation-related trauma. In contrast, bronchial blockers cause less trauma and are better tolerated by patients. This study compares the two lung isolation techniques to explore their advantages and disadvantages in lung isolation surgery. Methods: In this study, both the double-lumen bronchial tube group and the bronchial blocker group underwent surgery under general anesthesia combined with paravertebral block. Intubation time, quality of lung collapse, and postoperative complications such as hoarseness and sore throat were observed. Statistical analysis was performed using SPSS 20.0, with a P-value Results: The bronchial blocker group demonstrated shorter intubation and positioning times compared to the double-lumen bronchial tube group. The success rate of intubation was higher in the bronchial blocker group, while the incidence of postoperative hoarseness and sore throat was lower. No difference was observed in the quality of lung collapse between the two groups. Conclusion: For single-lung isolation, bronchial blockers achieve ideal lung isolation effects comparable to double-lumen tubes, with a higher success rate of intubation, less trauma to the glottis and throat, and significantly improved patient comfort.
