10 Questions
What is the primary concern when a patient with ischemic stroke is admitted to the emergency department?
Stabilizing the patient's vital signs and treating hypoglycemia
What is the significance of a 'hypodense area' on a CT brain scan in the context of ischemic stroke?
It confirms the presence of an ischemic stroke
What is the primary goal of thrombolytic therapy in the treatment of acute ischemic stroke?
To restore blood flow to the affected area of the brain
What is the significance of the 3.5-hour window in the context of thrombolytic therapy for acute ischemic stroke?
It is the maximum time allowed for administering thrombolytic therapy
What is the name of the medication used in thrombolytic therapy for acute ischemic stroke?
All of the above
What is the primary advantage of Tenecteplase over other thrombolytic agents?
It can be administered at a lower dose and is more cost-effective
What is the primary indication for performing an MRI perfusion and diffusion study in patients with acute ischemic stroke?
To assess the penumbra and determine the potential for thrombolytic therapy
What is the primary outcome of a CT brain scan that is 'free' in the context of acute ischemic stroke?
It rules out hemorrhage
What is the significance of the 'brain is time' concept in the context of acute ischemic stroke?
It highlights the need for rapid diagnosis and treatment of ischemic stroke
What is the primary goal of the 'TTT' approach in the management of acute ischemic stroke?
To rapidly diagnose and treat ischemic stroke, while also providing supportive care
Study Notes
Stroke Rehabilitation
- Physiotherapist plays a crucial role in rehabilitation after the first few days of stroke
- Medical TTT (Thrombolytic Therapy) and lifestyle changes are essential for prevention
- Prevention of stroke requires control of thrombus formation and medical TTT
Types of Stroke
- Ischemic stroke: characterized by a hypodense area in CT brain scans
- Hemorrhagic stroke: characterized by white color in CT scans
CT Brain Scans
- CT brain scan is essential to determine the type of stroke
- Ischemic stroke appears as a hypodense area in CT scans
- Hemorrhagic stroke appears as a white color in CT scans
TTT of Acute Ischemic Stroke
- TTT consists of maintenance of vital signs, specific TTT, and nursing care
- Thrombolytic therapy is administered within 3.5 hours of stroke onset
- Two types of thrombolytic therapy: Tissue plasminogen activating factor (TPA) and Tenecteplase
- TPA is commonly used in Egypt
- Tenecteplase is administered directly IV and is more cost-effective
- Advanced imaging techniques (MRI perfusion and diffusion) are used to identify penumbra area
- Thrombolytic therapy is administered if the patient is within the 3-4.5 hour window
Initial Assessment
- Initial assessment includes venous access, Ryle's tube insertion, and urinary catheterization
- Check for airway, breathing, and circulation (ABCs) before CT scan
- CT brain scan is essential to determine the type of stroke
