Acute Neuromuscular Respiratory Failure

Respiratory muscle weakness caused by neuromuscular disease can lead to both acute and chronic respiratory failure. Respiratory failure caused by Guillain-Barré syndrome and myasthenia gravis can potentially improve with disease-specific therapy. However, respiratory failure in amyotrophic lateral sclerosis is irreversible, and it may be necessary to provide full-time ventilation support along with additional assistance. Noninvasive ventilation is recommended for managing acute or acute-on-chronic hypercapnic respiratory failure caused by neuromuscular disease. It has also been effective in weaning patients off invasive mechanical ventilation. Although noninvasive ventilation offers numerous benefits over invasive mechanical ventilation, it is crucial to consider the specific contraindications and limitations of noninvasive ventilation and ensure its appropriate usage based on the patient's condition and needs. The timely recognition of neuromuscular respiratory failure is critical, as early intervention can be life-saving. This review focused on the clinical assessment and management of acute respiratory failure in neuromuscular diseases.
