Effect of electrode size in phrenic nerve CMAP
| Resumo: | Phrenic nerve (PN) investigation is a simple and safe non-invasive diagnostic tool widely utilized in assessing respiratory failure in patients with neuromuscular disorders [10]. In amyotrophic lateral sclerosis (ALS), PN amplitude has been shown to correlate with forced vital capacity, serving as a predictor of hypoventilation and survival. In intensive care units (ICU), PNI study can also provide valuable information regarding diaphragmatic function in critically ill patients. Additionally, reduced PN amplitude is associated with poor outcomes in Guillain-Barré syndrome. After Bolton, several technical aspects of PN CMAP recording have been discussed previously in the literature. Resman-Gaspersc and Podnar and Maranhão et al. have discussed the influence of the stimulation site, while Younis et al. have compared different recording sites. |
