Conclusion
Preoperative airway evaluation and intervention are the first step in perioperative airway management. In this study, we optimized some airway management measures, and further established a standardized preoperative airway management process for use in children with OSA, which showed it could rapidly improve abnormal lung function. In addition, patients with a history of chronic cough and asthma were more likely to have decreased lung function and could be further assessed/treated due to the potential increased risk for anesthesia. These results also suggest that for children who cannot complete lung function tests, if they have risk factors for lung dysfunction or symptoms of abnormal respiratory tract, we can give them preoperative atomization inhalation intervention to avoid possible perioperative airway adverse events. The disadvantage of this study was that there was no historical control group because previous children with OSA were not systematically examined for lung function before we established preoperative airway management procedures. However, the case series study can act as a pilot for future studies to provide a reference for preoperative standardized airway management.
