LOPEZ GASTON, O. et al. Polimiositis con incapacidad ventilatoria e insuficiencia respiratoria. Medicina (B. Aires) [online]. 2003, vol.63, n.5, pp.413-416. ISSN 0025-7680.

The inflammatory diseases of muscle are a group of disorders characterized by proximal muscle weakness. Most cases fall into three major diagnostic categories, polymyositis (PM), dermatomyositis and inclusion body myositis. Respiratory complications are a common feature and are an important cause of morbidity and mortality. The three main types of pulmonary involvement are interstitial lung disease, aspiration pneumonia and ventilatory incapacity (VI) due to muscle weakness. There are few reported cases in which mechanical ventilation has been used in patients with PM and VI in absense of lung disease. We present a patient with PM and VI due to muscle weakness who underwent therapy maintenance with mechanical ventilator and was weaned 4 months later.

Palabras clave : Polymyositis; Ventilatory incapacity; Hypercapnic respiratory failure; Mechanical respiratory assistance.
