Cardiovascular Responses to Nor-Epinephrine Before and After Denervation of the Pressoreceptors

Abstract
The doses of norepinephrine after denervation produced responses upon peak blood pressure, pressor response, and duration of pressor response which were all less than the predenervaiion responses to the same dose. The middle doses of the span tested were significantly lower after denervation and the responses to the highest and lowest doses were not significantly altered by denervation. After-fall was not significantly affected by denervation, but min. blood pressure was significantly lower following the highest doses after denervation. After denervation a diminution of pulse pressure and a number of arrythmias were noted following the highest doses.
