The Effect of an Oral Beta-2 Agonist on Respiratory Muscle Strength in SCI

B1910-P

Spinal cord injury (SCI), especially involving the cervical and upper thoracic segments, can significantly compromise respiratory muscle function. Respiratory complications can ensue, including lung collapse and pneumonia, which are the primary cause for mortality in association with traumatic SCI both during the acute and chronic phases post-injury. Lesions at the level of the cervical or high thoracic spinal cord result in respiratory muscle weakness, which is associated with ineffective cough, mucus retention, and mucus plugging. Despite the fact that pulmonary complications are a major cause of morbidity and mortality in this population, there is a paucity of effective interventions in the SCI population known to improve respiratory muscle strength with pharmacologic interventions receiving little to no attention. The current objective of this study is to determine the effectiveness of 16 weeks of sustained release oral Albuterol to; (1) improve respiratory muscular strength, and (2) improve cough effectiveness.
