Neurology Ix and Mx Flashcards
Ischaemic Stroke 1st Line Investigations
1st line:
• CT → to determine whether its an ishaemic or haemorrhagic stroke
• MRI
• Bloods + glucose
• Blood clotting → if patient is on warfarin and to exclude haemophilia or coagulopathy
• 24h ECG → look for AF
Ischaemic Stroke 2nd Line Investigations
2nd line:
• CXR → may show enlarged left atrium
• Echocardiogram → look for a cardiac source of emboli e.g. endocarditis, or mural thrombus due to AF
• Carotid Doppler US → for stenosis >70% is significant
Ischaemic Stroke Management
- ABCD approach → protect the airway
* Thrombolysis if onset of symptoms was
Haemorrhagic stroke Management
- ABCD approach
- Take them off anticoagulants if on them
- Nimodipine
- CT angiopraphy
TIA Investigations
- Bloods + glucose + lipids
- ESR + CRP
- CT
- CXR
- ECG
- Carotid Doppler US +- angiopraphy
- Echocardiogram
TIA Management
- ABCD approach
- Cautiously lower BP
- Clopidogrel
- Put on warfarin if caused by cardiac emboli
- Carotid endarterectomy if > 70% stenosis at the origin of the carotid artery and operative risk is good.
Menningitis Investigations
- FBC + glucose + coagulation screen
- U&Es
- LFTs
- CRP
- Blood culture
- Throat swabs
- Rectal swab
- Serology e.g. EBV, or HIV
- CT scan
- Lumbar puncture → after it if confirmed there is no raised Intercranial pressure
- Send CSF for MC&S, gram stain, protein, glucose, virology and lactate.
- CXR to look for signs of TB
Menningitis Management
- Start Abx immediately
- Once organism is isolated, seek urgent microbiological advice.
- Look for signs of disease causing the meningitis
- If ICP raised → seek neurosurgeon advice
- Prophylaxis → discuss with public health. Give Abx (rifampicin or ciprofloxacin) to household contacts and anyone who may have kissed the patients mouth.
