Does not support routine prophylactic autonomic blockade after subarachnoid hemorrhage; leaves open targeted trials in high-arrhythmia-risk subgroups.
Does the prophylactic administration of autonomic blockers alter outcomes in patients with subarachnoid hemorrhage?

Marion et al. (1986) studied this question.
