Abstract
Subarachnoid hemorrhage (SAH) is a condition defined by extraverted blood in the subarachnoid space. Blood activates meningeal nociceptors leading to occipital pain and meningism signs.1 Approximately 80% of patients with nontraumatic SAH have ruptured saccular aneurysms.1 If an SAH is left untreated, the patient will have a poor prognosis or will die. Therefore it is imperative that ED staff know how to recognize the early signs and start treatment immediately upon SAH confirmation. For the purpose of this article, SAH will be discussed from an ED perspective to include diagnosis and treatment.
