Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

Management

Evaluation Goal: Evaluation done within 60 mins of patient's arrival Check vitals ABCs Rapid Hx - time of onset, time of arrival at the ED, medications (especially anticoagulants) Rapid physical exam - neuro exam, NIHSS Activate stroke team Stat fingerstick Labs EKG, troponin, CXR NPO Obtain stroke protocol

Rule out DD Seizure, syncope, migraine, hypoglycemia
