Fiberoptic bronchoscopy can result in cough, laryngospasm, and/or bronchospasm.
Propofol and ketamine suppress N-methyl-d-aspartate receptors and thus can suppress coughing.
Ketamine and propofol did not decrease post-FOB cough during emergence.
Ketamine, greater than propofol, decreased emergence agitation.
Ketamine lengthened recovery time in children undergoing FOB.
