Q

How can we treat raised intracranial pressure?

Think conservative measures first, then medical and surgical

A
  1. Keep neck straight (helps drainage)
  2. Head tilt (helps drainage)
  3. Hyperventilation(reduces CO2, which has a vasodilator effect)
  4. Sedation (Barbiturate coma with phenobarbitone reduces metabolic demands)
  5. Fluids (maintain osmolarity and volume, prevent cerebral oedema)
  6. Mannitol (osmotic diuretic, draws water from the brain to reduce oedema)
  7. Decompressive craniectomy
  8. CSF drain

Q

What is the acute treatment pathway for migraine?

A

We treat the symptoms: Pain, N&V

  1. Aspirin 900mg dispersible or Paracetamol 1g If patient has N&V (signs of gastric paresis)
  2. Antiemetic: Domperidone, prochlorperazine or metoclopramide (improves medication absorption)
  3. Tristan: one dose of sumatriptan, zolmitriptan (CI = TIA, IHD, MI, HTN)

Q

What is the treatment pathway for bacterial meningitis?

A

1st line= Ceftriaxone, CT head and steroids

  1. Antibiotic: Ceftriaxone or cefotaxime (3rd generation cephalosporin)
    Or: benzylpenicillin if in GP setting
  2. CT head (exclude encephalitis)
  3. Add Dexamethasone

Other:
4. If patient is over 60 add amoxicillin

  1. If meningitis is Penicillin resistant = vancomycin or rifampicin
  2. If patient is allergic to penicillin or cephalosporin: chloramphenicol with dexamethasone
  3. If patient is over 60 and allergic to penicillin or cephalosporin: add co-trimoxazole

Q

What is the treatment pathway for giant cell arteritis?

Only one pathway

A

Oral prednisolone:

2. GCA = 40 to 60 mg daily
Ophthalmology referral

  1. Assess response within 48 hours
  2. Start aspirin 75 mg daily
  3. Start a PPI - omeprazole 20mg

6.Advise the person:

Treat with one drug only and build up dose slowly until maximum dose reached or seizures controlled.

18
Q

What is the treatment for focal onset seizures?

A

(First line) Carbamazepine or lamotrigine

Treat with one drug only and build up dose slowly until maximum dose reached or seizures controlled.

Treat with one drug only and build up dose slowly until maximum dose reached or seizures controlled.

20
Q

What is the treatment for myoclonic seizures?

A

(First line) sodium valproate.

Treat with one drug only and build up dose slowly until maximum dose reached or seizures controlled.

21
Q

What is the treatment for atonic or tonic seizures?

A

(First line) sodium valproate or lamotrigine.

Treat with one drug only and build up dose slowly until maximum dose reached or seizures controlled.

22
Q

When can anti-epileptic medication be started immediately?

A

Only if risk of recurrence is high:
Structural brain lesion
Focal CNS deficit
Unequivocal epileptiform EEG

23
Q

How long must a patient be seizure free before they can drive again?

A

One year

They must inform the DVLA immediately

25
Q

Do you normally monitor anti-epileptic medication blood levels?

A

No

Only circumstances requiring testing:
Non-adherence
Suspected toxicity
Adjustment of phenytoin dose
Management of interactions (other drugs)
Status epilepticus
Organ failure
