肺功能检测在儿童肺炎支原体肺炎致气道阻塞中的应用进展

Application progress of pulmonary function test in airway obstruction caused by Mycoplasma pneumoniae pneumonia in children

随着环境的改变和病原学检测方法的发展,肺炎支原体(MP)逐渐成为导致儿童呼吸道感染的主要病原体之一。MP感染后除咳嗽、发热等症状外,还会造成气道损害,主要表现为阻塞性通气功能障碍。肺功能检测(PFT)是以呼吸生理为基础的临床检测技术,是描述呼吸功能的一种重要检测方法。不论是在肺炎支原体肺炎(MPP)的急性期还是恢复期,利用PFT都可以准确判断由MP感染所造成的肺通气功能障碍,评估其肺通气功能损害的严重程度。哮喘患儿合并MP感染后可诱发哮喘发作,而且会明显降低他们的肺通气功能。在对这类患儿进行治疗时,可通过比较急性期与恢复期的肺功能相关指标的变化来评估肺通气功能的恢复情况,进而评估治疗疗效。本文将对近年来PFT应用于儿童MPP的最新研究作一综述并提出展望。

With changes in the environment and the development of pathogenic detection methods,Mycoplasma pneumoniae(MP)has gradually become one of the main pathogens causing respiratory infections in children.In addition to symptoms such as cough and fever,MP infection can also cause airway damage,which is mainly manifested as obstructive ventilation dysfunction.Pulmonary function testing(PFT)is a clinical testing technique based on respiratory physiology and an important testing method for describing respiratory function.Whether in the acute phase or recovery phase of mycoplasma pneumoniae pneumonia(MPP),PFT can accurately determine the ventilatory dysfunction caused by MP infection and assess the severity of lung ventilatory damage.MP infection in children with asthma can induce asthma attacks and significantly reduce their lung ventilation function.In the treatment of children with asthma and MP infection,the recovery of lung ventilation function can be evaluated by comparing the changes of lung function related indicators in the acute phase and the recovery phase,and then the therapeutic effect can be evaluated.This article will review the latest research on the application of PFT to children′s MPP in recent years and put forward prospects.
