Abstract
ObjectiveTo observe and compare the changes of pulmonary function in patients with pulmonary tuberculosis regular treatment for 3 months.
MethodsFrom April 2018 to June 2019, 500 tuberculosis patients who received regular anti tuberculosis treatment in our hospital were selected.The pulmonary function of patients with pulmonary tuberculosis was measured before treatment and at the end of three months; the results of pulmonary ventilation function, lung volume, diffusing capacity, and the value of forced vital capacity (FVC), maximum expiratory volume in 1 second (FEV1), maximum expiratory volume in 1 second/forced vital capacity (FEV1/FVC), total lung volume (TLC), residual volume (RV), carbon monoxide diffusing capacity (DLCO) were compared.
Results252 patients with pulmonary tuberculosis were included. Before treatment and at the end of three months, the abnormal pulmonary function results were 204 cases (80.95%) and 193 cases (76.59%), respectively, and the difference was not statistically significant (P>0.05). Among them, abnormal pulmonary ventilation function is the most common, especially with obstructive, followed by abnormal diffusing capacity. At the end of three months, the proportions of patients with normal pulmonary ventilation function and normal lung volume were higher than that before treatment (P<0.05), but there was no significant difference in the proportion of normal diffusing capacity before and after treatment (P>0.05). The values of FVC, FEV1, TLC and DLCO at the end of three months were higher than those before treatment, and the difference was statistically significant (t=-6.414, -6.754, -3.863, -3.311, all P<0.01).
ConclusionsMost patients with pulmonary tuberculosis have abnormal pulmonary function. At the end of the three months treatment, the normal rates of the pulmonary ventilation function and lung volume as well as the values of FVC, FEV1, TLC and DLCO in patients with pulmonary tuberculosis were significantly improved compared with those before treatment.
