[Perioperative airway management of nasal endoscopic surgery]

Objective:To evaluate the perioperative airway management process of nasal endoscopic surgery, and find clinical evidence for accelerating recovery and reducing respiratory complications. Methods:The perioperative airway management process for nasal endoscopic surgery was developed according to the patient's preoperative risk factors and preoperative pulmonary function. 512 patients who entered the airway management process from March 2019 to May 2020 were included. The improvement of pulmonary function and the occurrence of adverse respiratory events during the perioperative period were analyzed. Results:265 of 512 patients showed abnormal pulmonary function, including 203 cases with ventilatory dysfunction; 103 cases with positive bronchial provocation test; 59 cases with positive bronchodilation test. Patients with abnormal lung function were treated with aerosol inhalation for 3 to 5 days before surgery, the pulmonary function indicators were greatly improved（P<0.01）. After individualized airway management, patients were then treated with surgery, and there was no perioperative dyspnea event. Conclusion:Perioperative airway management can improve pulmonary function and reduce the risk of nasal endoscopic surgery.
