Cardiovascular and catecholamine responses to endotracheal intubation may differ according to the time elapsed and the level of injury in patients with complete spinal cord injury.
We examined whether nitrous oxide modifies the cardiovascular response to endotracheal intubation because it activates the sympathetic nervous system. Nitrous oxide attenuated the pressor response, whereas it augmented the norepinephrine response to laryngoscopy and endotracheal intubation.
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.
