Yang Y, Zhang Y, Yang Y, et al. - In this retrospective case series study involving 483 children (319 males and 164 females; 6 to 14 years), researchers sought to establish an optimized airway management process to improve preoperative lung dysfunction in obstructive sleep apnea (OSA). The sample consisted of children with OSA who underwent an adenotonsillectomy from November 2017 to December 2018. Lung function tests showed that 45 patients had obstructive ventilation dysfunction, and histories of chronic cough or asthma were identified as risk factors for perioperative abnormal lung function. Prior to performing surgery on children with OSA who have risk factors for abnormal lung function, it may be advantageous to establish an optimised airway management process to improve lung function before adenotonsillectomy.
