[Factors associated with the type of mask used during nocturnal NIV in patients with neuromuscular disorders]. / Facteurs associés au masque de ventilation non invasive nocturne chez les patients neuromusculaires adultes.

In subjects with neuromuscular diseases (NMD), the choice of facemask is essential for successful long-term noninvasive ventilation (NIV). While nasal masks usually represent the first line of treatment, almost a third of our subjects with NMD use an oro-nasal interface. Factors associated with the choice of mask remain poorly understood. We provide an original analysis of a previous prospective, multi-centric, Franco-Belgian survey investigating the factors associated with the type of nocturnal mask used in 116 adult NMD subjects treated with NIV. In these patients oro-nasal mask use was more often associated with non-Duchenne muscular dystrophy, older subjects, higher body mass index, better upper limb autonomy allowing independent mask removal and shorter periods of ventilation. Controlled prospective studies are needed to compare the efficacy and tolerance of different interfaces in this specific population.
