As we know “TIME is BRAIN” so early recognition of stroke is vital so BE FAST! Read more
In anybody who there is suspicion of a non-traumatic haemorrhage arrange an urgent CT Head.
All patients need IV access and U&E, FBC, Coag
If CT confirms PICH (not traumatic, not SAH): –
If anticoagulated with warfarin or NOAC discuss with stroke consultant and Haematologist regarding reversal
If not anticoagulated give Tranexamic acid – 1g in 100mls Saline/Glucose over 10 mins followed by 1g in 250mls Saline over 6 hours.
BP needs to be <150/80 – use labetalol (max 400mg – until BP <160 or HR <50) and GTN infusion
Not all patients with intracerebral bleeds need referral to neurosurgery – you could save yourself and your patient a lot of time and effort!
Those to refer:
- GCS 9-12/15 with lobar haemorrhage
- Isolated intraventricual haemorrhage
- Hydrocephalus on presentation
- Rapid deterioration following arrival (gcs drop by 2 points or more in the motor component)
- Cerebellar bleed
Admit those not going to Neurosurgery to HASU at CRH after discussion with Stroke team
When patients present with functional symptoms. It can be difficult to discern whether if it is an actual or functional weakness. And it can be even more difficult to convince the patient. However these tests can not only help you workout what is happening, but also demonstrate function to the patient. Read more

- BioChem: Hypokalaemia, Hypocalcaemia, Hypophosphataemia, Hyponatraemia
We all recognise the importance of ensuring patients with Parkinson’s disease (PD) get their medication, but..
What do you do if the patient can’t swallow?
We will need to work out what alternative routes we could use, for example dispensable via NG or patches, and what dose. For an ED clinical it is most likely beyond us and we need help! However, that may be extremely difficult to get especially Out of Hours
Excellent website that can give you options – select the patients normal regime (initially just one line but you can add as many as needed) and press calculate. It gives you a dispensable and patch dose, which can help the discussion with pharmacy about where we can get it
Bleeding on Dabigatran?
- <C>ABCD – as usual trying to stop bleed
- Bloods: FBC, Clotting, U&E, G&S
- Discuss with Haematologist (esp. if taken within 12-24hr)
- Idarucizumab (PRAXBIND) 5g IV
- Found in Emergency Drug cupboard
- We experienced delay finding as spelt wrong in the catalogue!
Headache is a common presentation to ED and Subarachnoid is the diagnosis we never want to miss. However, working out who needs a scan can be difficult as 50% of patients presenting with a subarachnoid have no neurological deficit.
The Ottawa SAH Rule is a validated tool for deciding who needs as CT scan. The Ottawa team have also done further work to decide which of the patients you do scan need a follow-up LP/CTA and who we could discharge. Read more
Advances in Acute Stroke Intervention
Dr Ian Rennie
Acute Stroke Thrombolysis only recannulates approximately 10% of large vessels.
MR CLEAN trial reduced disablED survivors following stroke from 53% to 29%. NNT <2 (New England Journal of Medicine 2015)
Dawn trial showed treatment up to 24 hours from “last well” can produce significant benefits. (New England Journal of Medicine 2018)
Included almost all patients for thrombectomy with large vessel occlusion who don’t have too much established infarct. No absolute cut off time, image vessels early.
Don’t treat those with a poor baseline function, extensive pmh, in hospital infarcts, established infarct on scan.
Pitfalls and Perils of Acute Neurology
Dr Thomas Peukert
Non orthopaedic cause of myelopathy (it’s not always cauda equina). ..
Think about onset…acute vs gradual
Think about time course…relapsing and remiting, deteriorating, stable, intermittent
If MRI spine is normal..have you imaged the right part of the spine? Is it too early? Have you imaged the right part or the right scan? Is the lesion not visible on MRI?
Is it a lesion in brain?
Is it a problem of neuromucular junction?
Is this a lower motor neuron lesion?
Spontaneous low pressure headache – sudden onset severe headache on standing can be associated with thoracic back pain due to spontaneous leak of csf often in the thoracic spine. Can pull brain downwards that looks like chiari malformation on MRI. Often associated with connective tissue disorders.
The Manchester Arena Major Incident
Mrs. Stella Smith
Patient id was a problem, the patients were carrying fake ID, particularly with transfusion, helped by ED based transfusion team.
Staff response needs to be tiered organisation by a distant member of staff helped.
Handovers needs to include everyone…managers, allied healthcare professionals, etc.
Ballistics and evidence collection training is needed by everyone as clothes, possessions, foreign bodies that are removed are all evidence.
Everyone needs Blast training….look in eyes, ears etc.
Managing a CBRN Incident
Dr Paul Russell
- Detect the incident…
- See. . ..self presenting toxidrome..123+ approach
- Hear ..take a history
- Smell..if it smells bad it is likely to be toxic
- Feel …unusual sensations
Many CBRN agents may have a delayed presentation or delayed detection so events may move on to other departments.
Protect yourself, collegues and environment
Decontamination should happen at scene however it often doesn’t happen.
Decontamination. ..remove clothes, blot dont rub with paper, wet decontaminate if needed.
Critical Care Research Update
Dr Rob MacSweeney
Polar trial – prehospital cooling for tbi and maintained for 7 days…no difference between 2 groups. Increased adverse events in cooled patients.
Eurotherm 3235 cooling raised icp patients caused harm, trial stopped early.
Rescueicp a decompressive craniectomy for icp>25mmhg, better icp control and more adverse events and no improvement in outcome
Paramedic2 adrenaline in shock refractory out of hospital cardiac arrest – adrenaline restarts heart and marginally improves survival but survivors had severe neurological impairment.
ALPS trial – Amiodarone, lidocaine, placebo in out of hospital cardiac arrest more likely to survive with drugs than placebo.
Eolia trial – ecmo for ARDS significantly improves survival at 60 days.
Florali – high flow nasal cannula oxygen vs face mask oxygen and niv for preoxygenation in patients with hypoxic respiratory failure needing RSI. Nasal Cannuale is best.
Beam trial boogie vs stylet for intubation with McGrath. ..boogie more likely to get 1st attempt intubation without complications.
IRIS trial – cricoid pressure vs sham pressure, no benefit from cricoid pressure.
Ideal-icu – when to start renal replacement therapy in severe sepsis induced renal failure at 12 hrs vs 48 hrs. ..no difference but very high mortality anyway.
Bicar-icu – bicarbonate for severe acidosis…some benefit of giving bicarbonate in severe acidosis.
Smart trial -Saline vs balanced crystolloid (Hartmans) for fluid resucitation in ICU, more adverse kidney events with saline.
Salt-ED Saline vs Hartmans in ED…no difference in hospital free days.
Adrenal trial -hydrocortisone vs placebo in Septic shock, reduced 90 mortality and reduced icu days with steroids.
Andromeda trial – shock treatment guided by peripheral perfusion vs Lactate guided resucitation …outcome better with perheral perfusion guided resucitation.
Censer trial – early noradrenaline in Septic shock reduces mortality
Tracheostomy Emergency Care – Dr Brendan McGarth
Needs to distinguish Tracheostomy from laryngectomy as a laryngectomy has no connection to the upper airway however a tracheostomy may have a connection so gives you 2 options for an airway.
Trachostomy problems commonly seen in the ED:-

The Impact of Dental Presentations to the ED — Chetan Trivedi
Facial imaging his a high dose of radiation to senative tissues in often young people therefore careful examination is required prior tor Xrays.
Predictors of radiological abnormality in facial trauma-
Tenderness over maxillary
Step deformity in maxillary
Sensory loss over site of injury
Change in bite
Abnormal eye signs
Predictors of radiological abnormality in mandibular trauma-
Restricted or painful mouth opening
Tenderness over mandible
Sensory loss over site of injury
Change in bite/painful bite
Try to assess carefully prior or to imaging
Acute Ophthalmology— Felipe Dhawahir-Scala
Viral conjunctivitis all have preauricular or submandibular lymphadenopathy, highly contagious.
Do not give chloramphenicol to contact lens wearers use something with a broader spectrum.
Urgent conditions (reasons to get an ophthalmologist out of bed) —
Acute angle closure glaucoma -red painful eye, semi dilated pupil, – start iv acetazolamide immediately
Orbital cellulitis – eye doesn’t move, colour vision loss, fever, chemosis, proptosis -start Ciprofloxacin and clarithromycin orally, image and call ophthalmology.
Vertigo – Peter Johns
Concerning features- new or sustained headache or neck pain it’s a stroke or vertebral artery dissection until we prove it isn’t.
A central cause …Unable to walk or stand unaided, Weakness in limbs, the Deadly d’s… dysarthria, diplopia, dysphagia, dysarthria, dysphoria.
Short episodes of Vertigo (spinning/dizziness) on getting up/rolling over in bed, no spontaneous or gaze provoked nystagmus.
(End gaze nystagmus so normal variant, look to 30 degrees only.)
Need dix-hallpike testing likely BPPV – posterior canal BPPV.
Treat with Epley manoeuvre.
Horizontal Canal BPPV – Dix-hallpike manoeuvre is negative and they are less clear which side they turn to to get dizzy.
Spontaneous or gaze provoked nystagmus for days, nausea and vomiting and gait disturbance likely to be Vestibular neuronitis.
Test using HINTS plus Exam– nystagmus, test of skew, head impulse test, hearing loss. All components have a central or peripheral result for each component. If all 4 are peripheral results then it is a acute Vestibular neuroitis
Vestibular migraine – 30% never get headache, can last hours or days.
More common in women, perimenopausal, often get photophobia, phonophobia, nausea, vomiting and other typical migraine symptoms.
