The deterioration of the respiratory function in children suffering from degenerative neuromuscular disease is the main cause of the high mortality rate associated with these diseases. Noninvasive ventilation (NIV) has reduced the morbidity and mortality due to respiratory insufficiency in these children. However, the use of support ventilation in some cases of spinal muscular atrophy (SMA) is still controversial. ⋯ In all of the symptomatic cases, a decrease in the frequency and severity of respiratory infections was observed, after ventilation was started. The respiratory support with NIV may improve the quality of life of children suffering from SMA as well as prolong their life expectancies. In SMA type I, whose clinical manifestations are precocious and whose prognostic is very serious, the application of this support has been debated.
