Objective Exploring the effectiveness of double lumen endotracheal intubation in anesthesia for thoracoscopic pulmonary bulla surgery. Methods Sixty-four patients undergoing thoracoscopic pulmonary bulla resection at Beijing Youlian Hospital (September 2018 to February 2021) were selected. Both groups received general anesthesia during surgery and were randomly divided into a control group (single-lumen bronchial intubation) and an observation group (double-lumen bronchial intubation), with 32 cases each. The perioperative hemodynamic parameters, single-intubation success rate, pulmonary function status, and complication rates were compared between the two groups. Results At the T1, T2, T3, and T4 time points, there were no statistically significant differences in hemodynamic indicators between the two groups when comparing each group's T2, T3, and T4 time points with T1 (P > 0.05). The one-time intubation success rates were 93.75% (30/32) in the observation group and 96.88% (31/32) in the control group, with no statistically significant difference (P > 0.05). The observation group exhibited relatively better postoperative pulmonary function indicators and a lower complication rate (12.50%) (P < 0.05). Conclusion Double-lumen bronchial intubation ventilation helps improve postoperative pulmonary function indices in patients, with a lower incidence of complications and better postoperative recovery. Compared to traditional single-lumen tube bilateral lung ventilation, it does not significantly increase hemodynamic fluctuations or first-attempt intubation success rates during surgery. However, double-lumen bronchial intubation ventilation offers greater flexibility during the procedure and contributes to improved patient outcomes.
