[Respiratory and intensive care aspects of muscular dystrophies].
Among the various myopathies, Duchenne muscular dystrophy represents the myopathy with the most stereotypical respiratory evolution. This progressive respiratory failure is going to develop in a parallel way of motor deficit, conducting patients to mechanical ventilation at the end of their second decade. In the absence of curative therapeutics, respiratory cares like home ventilation and prevention of respiratory complications, in a systematic and organized way, allowed to decrease the morbidity and the mortality of these patients. It is not exceptional to meet patients with life expectancy of which overtakes about forty. Besides axial stabilization, cough assistance techniques and swallowing disorders management need to be associated to mechanical ventilation. Invasive techniques of ventilation as tracheostomy keep their place in this pathology even if alternative techniques allowing full day non-invasive ventilation were generalized these last years.
