Headache Flashcards
Indications for hospital referral in cases of head injury?
loss of consciousness amnesia neurological symptoms evidence of skull fracture worrying mechanism
What are the signs of a basal skull fracture?
Panda eyes
haemotympanum (bruised ear drum)
Bruising over the mastoid (Battle sign)
CSF leakage from nose
NICE ED head scan rules
Loss of consciousness/amnesia >5 mins abnormal drowsiness, GCS <15 3+ discrete episodes of vomiting non-accidental injury post-traumatic seizure basal skull fracture dangerous mechanisms - high speed, fall from >3m slow/asymmetrical pupil reactions
Management of meningitis?
IM Benpen - 1.2mg
IV Abx (Ceftriaxone 2mg/12hrs) + IV Dexamethasone
Investigations in SAH
CT scan to confirm bleed
CT angiography to find source
consider LP if CT negative and suspicion high - blood in CSF is indicative
Management of SAH
Urgent neurosurgery referral
Keep BP >160 to maintain adequate cerebral perfusion
Nimodipine may reduce vasospasm and permanent CNS deficit
Clinical features of a space occupying lesion?
Raised ICP - headache worse on bending/lying/waking/coughing
Papilloedema is a late sign of ^ICP
Seizures, ataxia, cerebellar signs
CN 6 palsy is a false localising sign due to long intracranial course
Management of SoL
Imaging and surgery - CT/MRI +/- biopsy
seizure prophylaxis - phenytoin
opioid analgesic - codeine
^ICP - Dexamethasone, Mannitol
Clinical features of temporal arteritis
Headache, scalp tenderness over temporal artery - inflamed, pulseless, beaded
+/- tongue/jaw claudication
+/- amaurosis fugax - transient uni/bilateral visual loss due to retinal ischaemia
Investigations in temporal arteritis
Bloods - ESR and CRP ^^^, platelets ^, HB low
Temporal artery biopsy to confirm
Management of temporal arteritis
High dose, long term steroids - Prednisolone 40mg, daily
+ Aspirin 75mg daily + PPI cover
Patients may be on steroids for 2 years - relapse common
management of venous sinus thrombosis
elevate head to 30-40 degrees to relieve ^ICP
anticoagulation - LMWH/Heparin –> Warfarin
Decompressive hemicraniotomy may be necessary if ICP rises too high
