ABSTRACT
The occurence of respiratory failure in progressive neuromuscular disorders is well recognized. This failure is observed most commonly in Duchenne dystrophy but sometimes occurs in Becker's, limb-girdle, and facioscapulohumeral dystrophies. Patients usually present acutely or subacutely with cyanosis and cor pulmonale, with severe decompensation often being precipitated by an acute intercurrent infection. However, cardiopulmonary arrest is an uncommon presentation. A male diagnosed with limb-girdle muscular dystrophy type 2A who presented with cardiopulmonary arrest that was precipitated by an upper respiratory tract infection is presented. The nocturnal application of noninvasive intermittent positive pressure ventilation with a bilevel positive airway pressure (Bi-PAP) device improved his symptoms and quality of life without resorting to more-invasive and more-restrictive forms of support. This report demonstrates an unusual presentation of limb-girdle muscular dystrophy and documents that nocturnal nasal administration of continuous airway pressure using the Bi-PAP device may be sufficient to maintain adequate ventilation in such patients.
