Abstract
Objective To establish normal values of diaphragmatic structure and function in patients with COPD as a means of facilitating the use of B-mode ultrasound as a diagnostic tool in the evaluation of neuromuscular respiratory failure in patients with COPD and in the identification of high-risk patients prior to general anesthesia, mechanical ventilation, or invasive procedures such as needle electromyography (EMG) of the diaphragm. Methods Fifty patients with COPD and FEV <70% underwent B-mode ultrasonography. Three images were captured both at the end of expiration (Tmin) and at maximal inspiration (Tmax). The thickening ratio was calculated as Tmax/Tmin, and each set of values was averaged. The findings were compared with a database of 150 healthy control subjects. Results There was no significant difference in diaphragm thickness or thickening ratio between two sides of diaphragm in each group (control subjects or patients with COPD) or between the two groups, with the exception of the subgroup with severe air trapping (residual volume >200%), in which the only difference was that the thickening ratio was higher on the left ( p= 0.0045). Conclusions For evaluation of coexisting neuromuscular respiratory weakness in patients with COPD, the value of the same index established from healthy control subjects can be served as the baseline for comparison. This knowledge expands the role of ultrasound in evaluation of neuromuscular disease in patients with COPD.关键词
