Effects of combined anesthesia on pulmonary oxygenation function, hemodynamics, and respiratory compliance in elderly patients undergoing pulmonary lobectomy for lung cancer

Traditional general anesthesia in elderly lung cancer patients undergoing pulmonary lobectomy may lead to hemodynamic fluctuations and postoperative complications. To optimize anesthesia efficacy, this study explores the application of combined anesthesia (general anesthesia combined with thoracic paravertebral block) in such surgeries. We evaluated the improvement of pulmonary oxygenation function, hemodynamic stability, and respiratory compliance in elderly lung cancer patients undergoing pulmonary lobectomy with combined anesthesia. This retrospective study analyzed 100 elderly lung cancer patients who underwent pulmonary lobectomy at our hospital from February 2020 to December 2023. Patients were divided into 2 groups: the control group received general anesthesia, while the treatment group received combined anesthesia (general anesthesia plus thoracic paravertebral block). By comparing intraoperative hemodynamic parameters, postoperative pulmonary oxygenation function, respiratory compliance, cognitive function, sleep quality, and postoperative complication rates between the 2 groups, we assessed the application efficacy of combined anesthesia. Compared to the control group, the treatment group exhibited better hemodynamic stability intraoperatively, significantly improved postoperative pulmonary oxygenation function and respiratory compliance. Additionally, patients in the treatment group showed faster recovery of cognitive function, better sleep quality, and a relatively lower incidence of postoperative complications. Combined anesthesia demonstrates unique advantages in pulmonary lobectomy for elderly lung cancer patients, optimizing intraoperative hemodynamic stability, promoting postoperative pulmonary function recovery, accelerating cognitive function recovery, improving sleep quality, and potentially reducing the risk of postoperative complications. This finding provides a new effective strategy for anesthesia management in elderly lung cancer patients.
