Abstract：Objective: To observe the clinical effect of bronchial occluder in Thymectomy with the robot system of Leonardo da Vinci (rats). Methods: 48 patients who underwent thymectomy in our hospital from January 2018 to April 2019 were selected and included in this study. According to the different intubation methods, they were divided into two groups: double lumen endotracheal tube group (DLT group, n = 24) and bronchial occluder group (BBS group, n = 24). The anesthesia and operation methods of the two groups were basically the same, and the hands of the two groups were recorded The peak airway pressure (ppeak), PO2 and PCO2 were recorded at four time points before one lung ventilation (T1), 10 minutes after one lung ventilation (T2), 60 minutes after one lung ventilation (T3), and 10 minutes after two lung ventilation (T4), respectively. The voice hoarseness and throat pain and the incidence of complications were recorded. Results: There was no significant difference in the success rate of intubation and satisfaction rate of pulmonary collapse between the two groups (P>0.05). The intubation time and pulmonary collapse time of BBS group were longer than those of DLT group (P<0.05), and the rate of lateral displacement tube was higher than that of DLT group (P<0.05). The peak value of BBS group at T2 and T3 was lower than that of DLT group (P<0.05), but the pO2 and PCO2 of the two groups at T1, T2, T3 and T4 were poor The incidence of hoarseness and pharyngeal pain in BBS group was lower than that in DLT group (P<0.05). Conclusion: In Da Vinci's robotic thymectomy, the bronchial occluder has the advantages of low airway resistance and low incidence of postoperative pharyngeal pain. The patient's comfort is higher, but the time of lung collapse is longer. Compared with the double lumen bronchial tube, the two groups have similar effects and advantages.
