Slide2 l.jpg

Patient or bystander recognizes stroke

Dial 999

Ambulance response

Blue-light FAST positive potential strokes to A&E

Fits thrombolysis criteria pre alert A&E

Does not fit thrombolysis criteria

Immediate assessment

Thrombolysis pathway and CT within 15 min

Stroke pathway and CT within 1 hour

Thrombolysis

Admit to ASU within 4 h of presentation



F a s t l.jpg
F A S T

Face–Arm–Speech Test

F Facial weakness: Can the person smile? Has their mouth or an eye drooped?

A Arm weakness: Can the person raise both arms?

S Speech problems: Can the person speak clearly and understand what you say?

T Time to call 999.

ROSIERRecognizing Stroke in the Emergency Room

Only count new symptoms

Exclude hypo by BM stix

Unilateral facial weakness? y (1) n (0)Unilateral arm weakness? y (1) n (0) Unilateral leg weakness? y (1) n (0) Speech disturbance ? y (1) n (0) Visual field defect? y (1) n (0) Any loss of consciousness or syncope y (-1) n (0) Any seizures? y (-1) n (0)

Rosier >0 suggests ischaemic stroke and potential thrombolysis case


Stroke or tia l.jpg
Stroke or TIA?

  • Symptoms still present => Stroke

  • Symptoms gone =>TIA


Who definition of stroke l.jpg
WHO DEFINITION OF STROKE

A NEUROLOGICAL DEFICIT OF

  • Sudden onset

  • With focal rather than global dysfunction

  • In which, after adequate investigations, symptoms are presumed to be of non-traumatic vascular origin

  • and last for >24 hours


Stroke onset l.jpg
Stroke onset

  • Witness?

  • Woke with hemiparesis?

  • Found collapsed?

  • Sudden/gradual/ stuttering


Abcd2 scoring for all new tias l.jpg
ABCD2 Scoring for all new TIAs

Stroke risk within 1 week 6% for scores 4-5, 12% for scores >5

Admit all with score 5 or above.


Tia management l.jpg
TIA management

  • Do not allow any TIA patient to leave the department without having administered the first dose of antiplatelet

  • ABCD 4 or above admit or ensure TIA clinic appointment (and Doppler) within 24 hours.

  • Endarterectomy within 48 h for patients with symptomatic stenosis

  • ABCD <4 see in TIA clinic within 1 week. Endarterectomy within 14 days for patients with symptomatic stenosis

    This will reduce strokes within 1 week by 80%!!!


Role of paramedics l.jpg
Role of Paramedics

  • Establish working diagnosis of stroke/TIA

  • Identify potential thrombolysis candidates

  • Prealert A&E if thrombolysis an option

  • Establish onset time

  • Bring a witness

  • Airway Breathing Circulation

  • Exclude Hypo BM

  • Prevent aspiration

  • Get patient to nearest hyper acute stroke centre



Ct head scan l.jpg
CT Head scan

  • Intracerebral haemorrhage

  • Correct abnormal INR or low platelets immediately

  • Neurosurgical referral

  • Cerebral Infarct

  • Thrombolysis or

  • immediate antiplatelet treatment

DH A New Ambition for StrokeA consultation document for a National Stroke strategy Dec 2008

If 10% of stroke patients in the UK were given thrombolysis, 1000 people less would be dead or dependent in one year.

Ninds trial of rt pa for acute ischaemic stroke l.jpg
NINDS trial of rt-PA for acute ischaemic stroke

  • 633 patients recruited

  • Rt-PA 0.9 mg/kg (10% bolus the rest over 1 h) given within 3 hrs of symptom onset

  • BP<185/110

  • Not on warfarin or heparin, platelets and coagulation normal

  • Blood glucose 2.7-22 mmol/L

  • No seizure at onset

    Quasi intensive care environment

    Aggressive BP control

    16,000 screened to recruit 633

    N Engl J Med 1995;333:1581-1587.

Most complications of stroke develop in the first 24 hours

Management in the first few hours has a major effect on outcome and LOS


Important factors for successful early stroke rehabilitation l.jpg
Important factors for successful early stroke rehabilitation

  • Mobilise ASAP

    The probability of returning home decreases by 20% for each

    day the patient is not mobilized

  • Maintain normal haemodynamic and biochemical environment

  • Prevent complications

  • Keep patient and family informed



2 prevent aspiration l.jpg
2. Prevent Aspiration

  • Swallow screen on arrival on ASU

  • Sit up

  • Drowsy patients in recovery position

  • Antiememtics for haemorrhages and patients who feel sick

  • All members of staff have at least basic knowledge of the diagnosis and management of swallowing problems


3 prevent hypotension and dehydration l.jpg
3. Prevent hypotension and dehydration

  • IV saline

  • Sufficient fluids by mouth or ngt

Mobilization


Mouthcare l.jpg

Dysphagic patients have impaired oral movements resulting in debris, pooled secretions and

tongue coating.


5 prevent hospital acquired infections mrsa esbl c difficile l.jpg
5. Prevent hospital acquired infectionsMRSA/ ESBL/ C.Difficile

Avoid catheters at all costs

Hand hygiene

Bed spacing

Appropriate antibiotics



7 prevent stagnation and deterioration l.jpg
7. Prevent stagnation and deterioration

  • Time does not cure strokes

  • Give at least 45 min of each therapy needed every day 7/7


7 detect and treat problems early l.jpg
7. Detect and treat problems early

  • 72 hour monitoring

  • Neurological scores (NIHSS/SSS)

  • Daily consultant ward rounds 7/7
