Endobronchial valve treatment improves diaphragm function in severe emphysema patients.

ABSTRACT:

Background

Diaphragm dysfunction is common in severe emphysema patients, primarily due to hyperinflation, placing the diaphragm at a mechanical disadvantage. Endobronchial valve (EBV) treatment is a bronchoscopic procedure to reduce hyperinflation and thus potentially restore diaphragm function in this patient population. Our aim was to investigate the effect of EBV treatment on diaphragm function.

Methods

A prospective cohort study was performed in which diaphragm function was measured at baseline and 6 weeks after EBV treatment by ultrasonic assessment to measure diaphragm motion and diaphragm thickening fraction, surface electromyography (sEMG) to quantify diaphragm activity, and maximal inspiratory pressure to assess diaphragm strength.

Results

25 patients were in
