Abstract: Objective To establish the preoperative airway management protocol for children with obstructive sleep apnea hypopnea syndrome(OSAHS)by departments of otolaryngology and allergy under the guidance of enhanced recovery after surgery(ERAS)concept, analyze the perioperative pulmonary function of pediatric OSAHS patients and the improvement of pulmonary function before and after airway intervention, so as to provide a clinical basis for the role of airway management of pediatric OSAHS in ERAS. Methods The preoperative pulmonary function evaluation and airway management process of pediatric OSAHS patients was established according to the previous history of lower airway diseases, preoperative risk factors, preoperative pulmonary function and other factors. During Nov. 2017 and Dec. 2018, 483 pediatric OSAHS patients pulmonary function was assessed according to this procedure. Children with abnormal pulmonary function were interfered with atomization inhalation treatment, children with adenoid hypertrophic re- 山 东 大 学 学 报 (医 学 版)57卷9期 -郭静,等.气道管理流程在儿童阻塞性睡眠呼吸暂停低通气综合征患者加速康复中的应用 \=-ceived pulmonary function evaluation, and intraoperative and postoperative airway adverse events were observed. Results Of the 483 children, 56 had complicated asthma, 62 had abnormal pulmonary function, including 13 cases with restricted ventilatory dysfunction, 24 had obstructive ventilation dysfunction, 41 had small airway dysfunction and 36 had positive results of bronchodilation test. Children with abnormal lung function showed significant improvement after atomization inhalation treatment (P<0.05), and could well tolerate general anesthesia. All children followed the perioperative airway management process, and no adverse airway events occurred during and after operation. Conclusion The establishment of airway management process can significantly improve the preoperative lung function of children with OSAHS, reduce perioperative risks, facilitate the smooth operation and accelerate the recovery of children.
