Intraoperative management and postoperative outcomes of patients with high body mass index undergoing tubeless anesthesia for non-intubated uniportal video-assisted thoracoscopic surgery: a single-center retrospective propensity score matching study

Background: Tubeless anesthesia for non-intubated uniportal video-assisted thoracoscopic surgery (NI-UniVATS) has been widely used in various thoracic surgical procedures. However, most patients selected for this procedure have a normal body mass index (BMI), and the impact of this surgery on patients with high BMI (H-BMI) remains unclear. The study aims to evaluate the perioperative course of NI-UniVATS in H-BMI patients. Methods: ). The intraoperative management and postoperative outcomes of the two groups were comprehensively compared. Results: . 5,350.37±1,511.90, P=0.23) between the two groups. Conclusions: Compared with NH-BMI patients, H-BMI patients undergoing NI-UniVATS have similar intraoperative conditions and postoperative outcomes, but require more intraoperative anesthetic adjustments.
