Abstract
The cough assessment is fundamental in the weaning process as it gives information on the possibility to expel food and secretion from the airways. The majority of persons suffering from severe acquired brain injury (ABI) are not able to cough voluntarily due to severe motor deficits. In the present study, we evaluated the cough reflex in ABI patients using a new method based on a capsaicin spray stimulation test. 100 Healthy controls demographically matched with 50 ABI patients were included in this study. Clinical observations demonstrated robust cough response in both healthy controls and ABI patients, as well as the safety and tolerability of capsaicin spray stimulation. ABI patients with dysphagia were characterized by slower and delayed cough responses. Further studies are needed to validate this feasible, less-invasive, and simple-to-comprehend technique in inducing cough reflex. According to this preliminary evidence, we believe that this test might be translated into a simple and effective treatment to improve cough strength training reflexive cough modulation in ABI patients.
