摘　　要：目的探讨支气管哮喘患者急性发作期及症状缓解期影像学检查与肺功能检测的结果分析。方法选取70例支气管哮喘患者,其中急性发作期(35例)为实验组,症状缓解期(35例)为对照组,对比急性发作期及症状缓解期患者的影像学检查与肺功能各项指标变化情况。结果 77%的急性发作期支气管哮喘患者有影像学改变,表现为支气管壁增厚、双肺透亮度增加、双肺纹理增粗、肺过度膨胀等,症状缓解期支气管哮喘患者31%有以上影像学的改变(P<0.05);两组患者肺功能各项指标(第一秒用力呼气量、一秒率、呼气峰流量、用力肺活量、残气容积、残气量与肺总量百分比)差异均有统计学意义(P<0.05);同时,急性发作期支气管舒张试验阳性率高于症状缓解期(P<0.05)。结论影像学检查作为呼吸科的首选检查,对支气管哮喘的评估和监测具有重要价值;肺功能检测可反映支气管哮喘气流受限情况,评估哮喘严重程度,指导临床用药;支气管舒张试验是气道可逆性检查一种方法,针对性强,对气道可逆性改变有重要的临床诊断意义和治疗指导价值;影像学检查结合肺功能检测可提高支气管哮喘的诊治率。Objective To investigate the results of imaging and pulmonary function tests in patients with acute exacerbation and remission of bronchial asthma.Methods A total of 70 patients with bronchial asthma were included in this study,The acute exacerbation period(35 cases)was the experimental group and the remission stage(35 cases)was the control group.Comparing the changes of the imaging and pulmonary function indexes in patients with acute exacerbation and remission.Restults 77%of acute exacerbation of bronchial asthma patients with imaging changes,manifested as thickening of the bronchial wall,increased lung brightness,thickening of the lung,excessive lung expansion,31%of patients with remission bronchial asthma have the above imaging changes(P<0.05);The indexes of pulmonary function(FEV1,FEV1/FVC%,PEF,FVC,RV,RV/TLC%)in both groups were also significantly different(P<0.05);At the same time,the positive rate of bronchial dilation test in acute exacerbation was higher than that in remission(P<0.05).Conclusion Imaging examination as the first choice of respiratory department,which is of great value in the assessment and monitoring of bronchial asthma;The pulmonary function tests can reflect the limited air flow in bronchial asthma,assess the severity of asthma and guide the clinical medication;Bronchial diastolic test is a method of airway reversibility examination,targeted and is great significance to guide the clinical diagnosis and treatment of airway reversible changes;Imaging studies combined with pulmonary function tests can improve the diagnosis and treatment of bronchial asthma.
