节段性肺炎支原体肺炎患儿肺功能检测的临床意义

目的探讨节段性肺炎支原体肺炎(SMPP)患儿肺功能变化及临床意义。方法分别测定55例SMPP患儿急性期和恢复期的肺功能,包括FVC、FEV1、FEV1/FVC、PEF、FEF25%、FEF50%、FEF75%、FEF25%-75%。结果 55例SMPP患儿急性期FVC、FEV1、FEV1/FVC、PEF、FEF25%、FEF50%、FEF75%及FEF25%-75%均有不同程度降低,以FEF25%、FEF50%、FEF75%和FEF25%-75%降低较为明显。恢复期各项指标均有明显改善,两组比较差异有统计学意义(P<0.05)。多部位病变SMPP患儿急性期FVC和FEV1较单个叶段病变患儿下降明显(P<0.05)。结论 SMPP患儿急性期大、小气道功能均有不同程度损伤,多表现为限制性通气障碍,小气道功能受损更明显;恢复期肺功能明显好转。多叶段病变大气道功能受损较单个叶段病变严重。

Pulmonary functions in children with segmental Mycoplasma pneumoniae pneumonia

Objective To investigate the changes of pulmonary functions in children with segmental Mycoplasma pneumoniae pneumonia(SMPP). Methods A total of 55 children with SMPP were recruited into this study.Pulmonary functions were measured at both acute and recovery phases,including FVC,FEV1,FEV1/FVC,PEF,FEF25%,FEF50%,FEF75% and FEF25%-75%. Results FVC,FEV1,FEV1 /FVC,PEF,FEF25%,FEF50%,FEF75%,and FEF25%-75% were reduced in all of the 55 cases at the acute phase.FEF25%,FEF50%,FEF75% and FEF25%-75% decreased more sign...
