Abstract：Objective To explore the effect of continuous positive airway pressure(CPAP)ventilation on respir-atory function in patients undergoing thoracoscopic lung surgery.Methods A total of 60 patients who underwent elective thoracoscopic lung surgery in the People's Hospital of Guangxi Zhuang Autonomous Region from June 2021 to December 2022 were selected and divided into observation group and control group by random number table method,with 30 cases in each group.After exclusions,29 cases were included in each of the two groups for analysis.During one-lung ventilation,the observation group received CPAP ventilation on the surgical side of the lung,with a pressure of 5 cmH2O,while the control group received no special intervention measures on the surgical side of the lung.Arterial blood gas analysis was performed at the time point of two-lung ventilation for 20 minutes(T0),the time point of one-lung ventilation for 30 minutes(T1)and the time point of one-lung ventilation for 1 hour(T2),and oxygenation index(OI)level was com-pared between the two groups at each time point.The neutrophil ratio and white blood cell count were compared between the two groups before operation and 24 hours after operation.The incidence of pulmonary complications within 72 hours after operation was compared between the two groups.Results At the time points from T0 to T2,OI in both groups showed a downward trend(P＜0.05),and at the time points of T,and T2,OI levels in the control group were lower than those in the observation group,and the differences were statistically significant(P＜0.05).After operation,the white blood cell count and the neutrophil ratio in the two groups were significantly higher than those before operation(P＜0.05),and there were no statistically significant differences between the two groups(P＞0.05).The incidence of postoperative pulmonary complications in the observation group was lower than that in the control group,and the difference was sta-tistically significant(13.79％vs 37.93％;x2=4.406,P=0.036).Conclusion The implementation of CPAP venti-lation in the surgical side of the lung in the patients undergoing thoracoscopic lung surgery can effectively improve the oxygenation of the patients with one-lung ventilation and reduce the incidence of postoperative pulmonary complications.
