Propofol, when used as a sedative for FOB, is associated with lower hemodynamic side effects than in patients undergoing FOB with midazolam. In addition, it is well-tolerated by patients with pre-existing pulmonary disease. Even patients without a history of heart disease should be monitored for cardiac arrhythmia while undergoing FOB for pulmonary disease, especially patients with a FEV (1) of less than 50 % of the predicted value.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
