目的探讨儿童患支原体肺炎后肺功能的变化情况,分析其对人体肺脏的功能损害。方法 120例支原体肺炎患儿作为观察组,另选取120例同龄健康儿童作为对照组。以德国耶格Master Scope肺功能仪作为肺脏功能性检测判断仪器,分析对比两组诊断结果。结果观察组患儿高峰流速时间/呼气时间、到达高峰流速呼出气量/呼气容积、剩余25%潮气量呼气流速以及该时段呼气流速/呼气峰值等指标均低于对照组(P<0.05)。结论儿童患支原体肺炎后会对肺脏造成一定损伤,表现一般为小气道阻塞性通气功能障碍,而儿童大气道呼吸能力未有明显影响;同时潮式呼吸测定法能够利用在儿童肺部功能参数的测定上,具有临床意义,也能够为诊断和治疗提供一定的参数依据。
Objective To investigate the changes of pulmonary function in children with mycoplasma pneumonia and analyze the functional impairment of human lung. Methods 120 cases of mycoplasma pneumonia children as the observation group, another 120 healthy children of the same age as the control group. Taking the German Master Scope Pulmonary Function Instrument as the lung function test and judgment instrument, the two sets of diagnostic results were analyzed and compared. Results The peak flow time / expiration time, peak expiratory volume / expiratory volume, the remaining 25% tidal volume expiratory flow in the observation group and the expiratory flow / expiration peak in the observation group were all lower than those in the control group (P <0.05). Conclusion Mycoplasma pneumonia caused some damage to the lungs in children, the general performance of small airway obstructive ventilatory dysfunction, while children’s airway respiration ability had no significant effect; while tidal breath method can be used in children with lung function parameters Determination, with clinical significance, but also for the diagnosis and treatment to provide some parameters.
