Why the study?
Does intravenous propranolol alter cardiovascular and renin-angiotensin system responses during sodium nitroprusside-induced hypotension in anesthetized patients?
Does intravenous propranolol alter cardiovascular and renin-angiotensin system responses during sodium nitroprusside-induced hypotension in anesthetized patients?
Propranolol administration during sodium nitroprusside-induced hypotension blunts reflex tachycardia and increased cardiac output, while also inhibiting renin release.

May blunt reflex tachycardia and renin release during nitroprusside hypotension; hypothesis-generating and should not yet change practice.
Marshall et al. (1981) studied this question.
