呼吸道发热患者肺功能检测的临床意义

Clinical Significance of Examining Pulmonary Function of Respiration Patient with Fever

目的探讨呼吸道发热患者的体温、白细胞计数、肺部炎症对肺功能的影响。方法对呼吸道发热患者进行肺功能、血常规、胸片等检查,并与健康对照组进行统计分析。结果实验组中体温≥38.5℃与<38.5℃、白细胞<10.0×109与≥10.0×109组之间肺功能没有统计学差别,支气管炎组在MVV、FEV1/FVC和FEF25%～75%方面降低,而肺炎组VC、FVC和MVV减少,与胸片正常组比较有统计学意义。在实验组中VC、FVC、MVV、FEV1/FVC和FEF25%～75%比正常对照组低,但没有统计学意义(P>0.05)。结论呼吸道发热患者肺功能与体温的高低、白细胞计数的多少无关,与气管及肺部炎症有一定关系。

Objective To investigate the effect of body temperature, white blood cell count, inflammation of respiration tract on pulmonary function in fever cases. Methods Pulmonary function tests （PFY） and blood examination and chest X - rays were performed in 138 fever cases of respiration outpatient （study group）. At the same time, pulmonary functions of 30 healthy persons were confronted （control group）. Results There was no statistical difference between T ≥38.5℃ and T 〈 38.5 ℃, WBC 〈 10. 0 × 10^9 and WBC ≥ 10. 0× 10^9 in study groups. Significantly reduction was observed in maximum voluntary ventilation （MVV）, FEV1 divided by FVC （FEV~/FVC）, forced expiratory flow 25% to 75% （FEF 25% -75% ） of patients with bronchitis and in vital capacity （VC）, forced vital capacity （FVC）, maximum voluntary ventilation （MVV） of patients with pneumonia too, there was significant difference between bronchitis, pneumonia and chest X - rays normal in study groups. There was no statistical reduction in VC, FVC, MVV, FEV1/FVC, FEF 25% -75% of study groups than those of control groups. Conclusion There wasn＇t relation between pulmonary function changes of fever cases of respiration outpatient and body temperature, white blood cell count, however, they were related to inflammation of respiration tract.
