Comment on the 2023 Guidelines for the Management of Patients With Aneurysmal Subarachnoid Hemorrhage

Aneurysmal subarachnoid hemorrhage can be a devastating disease, with an in-hospital mortality rate of up to 20%. The American Heart Association/American Stroke Association 2023 Aneurysmal Subarachnoid Hemorrhage Guidelines provide a comprehensive update to the 2012 Guidelines based on a systematic review of the intervening evidence. The guidelines are broad in scope, covering prehospital care, aneurysm treatment modality, medical complications, detection and treatment of delayed cerebral ischemia, and recovery. Here, we comment on salient aspects of aneurysmal subarachnoid hemorrhage care, compare these guidelines with the 2023 Neurocritical Care aneurysmal subarachnoid hemorrhage guidelines, and review relevant updates.
