From March 2022 to February 2023, a total of 46 patients aged between 37 and 80 years were enrolled in the study. Of these, 2 patients were excluded due to refusal to sign informed consent (n = 1) or a halfway change in the type of surgery (n = 1). A total of 44 patients (27 males and 17 females) were randomized to the study, 22 in Group E and 22 in Group S. Patients followed the standardized anesthetic and surgical procedures and completed all evaluation items. Finally, we performed a statistical analysis of the data from 44 patients and created a flow diagram for the trial (Fig. 
Flow diagram for the trialThe demographic characteristics, ASA classification, vital signs and comorbidities were relatively comparable between the two groups. A total of 51 pulmonary lesions were ablated in this study. One case was not completely ablated because the lesion was too large and closely adjacent to the blood vessels, and the total ablation rate was 50 cases (98.4%).There was no significant difference in the long diameter of the target lesion, distance between the lung tumors and the pleura, or ablation tumor numbers between Group S and Group E (Table
