ABSTRACT
Objective:To correlate diaphragmatic ultrasound parameters and pulmonary function in patients with chronic obstructive pulmonary disease (COPD) and its clinical value in the diagnosis of COPD.Methods:Eighty patients with COPD who received treatment in The First People's Hospital of Huzhou from January 2019 to June 2020 and 80 healthy subjects who concurrently received health examination were included in this study. Pulmonary function index, diaphragmatic ultrasonic parameters and activity endurance index were compared between COPD group and healthy control group. Diaphragmatic ultrasound parameters in COPD patients were correlated with pulmonary function index and activity endurance index.Results:The forced expiratory volume in 1 second/forced vital capacity (FEV 1/FVC) ratio in the COPD group was significantly lower than that in the healthy control group [(56.27 ± 8.98)% vs. (87.42 ± 6.29)%, t = 14.583, P < 0.05]. The residual volume/total lung capacity (RV/TLC) ratio in the COPD group was significantly higher than that in the healthy control group [(54.81 ± 6.95) % vs. (27.59 ± 3.92) %, t = 17.904, P < 0.05]. The walking distance in 6-minute walking test (6MWT) in the COPD group was significantly shorter than that in the healthy control group [(502.36 ± 82.41) m vs. (824.59 ± 63.37) m, t = 11.726, P < 0.05]. The diaphragm mobility using quite breathing (DM QB), the diaphragm mobility using deep breathing (DM DB), and diaphragmatic thickening fractions (TF) in the COPD group were (1.71 ± 0.45) mm, (4.03 ± 0.81) m and (117.56 ± 24.83) %, respectively, which were significantly lower than those in the healthy control groups [(2.24 ± 0.30) mm, (5.36 ± 0.62 ) mm, (159.60 ± 22.35)%, t = 4.736-7.592, all P < 0.05]. DM QB, DM DB and TF in patients with COPD were positively correlated with FEV 1/FVC and 6MWT distance ( r = 0.705-0.819, all P < 0.05), but they were negatively correlated with residual volume/total lung capacity (RV/TLC) ratio ( r = -0.774 to -0.847, all P < 0.05). Conclusions:DM QB, DM DB and TF decrease in COPD patients, and their values are correlated with pulmonary function and activity tolerance index. Ultrasound examination of diaphragmatic morphological change is of certain clinical value for the diagnosis and evaluation of COPD.
