When should Nihss be performed?
A NIHSS score should be done and documented within 12 hours of hospital arrival for patients who do not receive a reperfusion therapy.
What levels must be measured before initiating stroke treatment?
Patients with suspected acute stroke should have a rapid initial evaluation for airway, breathing and circulation [Evidence Level A].
What is the American Heart Association’s goal for door to CT time in the majority of patients who present to the ED with stroke like symptoms?
The goal of the stroke team, emergency physician, or other experts should be to assess the individual with suspected stroke within 10 minutes of arrival in the emergency department (ED). The CT scan should be completed within 10-25 minutes of the individual’s arrival in the ED and should be read within 45 minutes.
What are the recommended time frames for treatment of acute ischemic stroke?
All eligible patients with disabling ischemic stroke should be offered intravenous alteplase [Evidence Level A]. Eligible patients are those who can receive intravenous alteplase within 4.5 hours of the onset of stroke symptoms [Evidence Level A].
Why is the NIHSS important?
The NIHSS score is important for patients because it determines the course of action and treatment following a stroke. First, healthcare staff apply the NIHSS score as soon as possible after the onset of symptoms—which would typically be in the emergency department of a hospital.
What are stroke protocols?
A CT stroke protocol is obtained in the emergency setting to rapidly diagnose and quantify patients presenting with probable ischemic strokes and to enable appropriate urgent management (e.g. endovascular clot retrieval or intravenous thrombolysis).
What is door to CT time?
Goal time for door to CT is 25 minutes. Average time for door to CT is currently 30 minutes. 40% of stroke code activations are within goal time for door to CT metric.
How do you read CT perfusion?
The key to interpreting CT perfusion in the setting of acute ischemic stroke is understanding and identifying the infarct core and the ischemic penumbra, as a patient with a small core and a large penumbra is most likely to benefit from reperfusion therapies.
What is tPA protocol?
Administer within 30 minutes of hospital arrival. Adults greater than or equal to 67 kg get 100 mg total dosage administered as a 15 mg IV bolus, followed by 50 mg IV infused over 30 minutes, and then 35 mg IV infused over the next 60 minutes.
Why must tPA be given within 3 hours?
The timing of treatment is important, because giving a strong blood thinner like tPA during a stroke can cause bleeding inside the brain. The longer a patient waits to get treatment, the more likely it is that the risks of treatment will outweigh the benefits.
