Creating Acute Stroke Services Diagnosing Screening Acute Care pathways Thrombolysis Dr C. Roffe Clinical Lead Shropshire and Staffordshire Heart and Stroke Network

Patient or observer perceives stroke Dial 999 Ambulance reaction Blue-light FAST constructive potential strokes to A&E Fits thrombolysis criteria pre caution A&E Does not fit thrombolysis criteria Immediate appraisal Thrombolysis pathway and CT inside 15 min Stroke pathway and CT inside 1 hour Thrombolysis Admit to ASU inside 4 h of introduction

Diagnosing Stroke and TIA

F A S T Face–Arm–Speech Test F Facial shortcoming: Can the individual grin? Has their mouth or an eye hung? An Arm shortcoming: Can the individual raise both arms? S Speech issues: Can the individual speak clearly and comprehend what you say? T Time to call 999.

ROSIER Recognizing Stroke in the Emergency Room Only check new side effect s Exclude hypo by BM stix Unilateral facial shortcoming? y (1) n (0) Unilateral arm shortcoming? y (1) n (0) Unilateral leg shortcoming? y (1) n (0) Speech unsettling influence ? y (1) n (0) Visual field imperfection? y (1) n (0) Any loss of cognizance or syncope y ( - 1 ) n (0) Any seizures? y ( - 1 ) n (0) Rosier >0 proposes ischaemic stroke and potential thrombolysis case

Stroke or TIA? Side effects still present => Stroke Symptoms gone =>TIA

WHO DEFINITION OF STROKE A NEUROLOGICAL DEFICIT OF Sudden onset With central instead of worldwide brokenness In which, after sufficient examinations, manifestations are attempted to be of non-traumatic vascular root and keep going for >24 hours

Stroke onset Witness? Woke with hemiparesis? Discovered crumpled? Sudden/continuous/stammering

ABCD2 Scoring for every single new Tia Stroke hazard inside 1 week 6% for scores 4-5, 12% for scores >5 Admit all with score 5 or above.

TIA administration Do not permit any TIA patient to leave the division without having controlled the main measurement of antiplatelet ABCD 4 or above concede or guarantee TIA facility arrangement (and Doppler) inside 24 hours. Endarterectomy inside 48 h for patients with symptomatic stenosis ABCD <4 find in TIA center inside 1 week. Endarterectomy inside 14 days for patients with symptomatic stenosis This will decrease strokes inside 1 week by 80%!!!

Role of Paramedics Establish working finding of stroke/TIA Identify potential thrombolysis competitors Prealert A&E if thrombolysis an alternative Establish onset time Bring a witness Airway Breathing Circulation Exclude Hypo BM Prevent yearning Get patient to closest hyper intense stroke focus

Investigations and tests in the early stages

CT Head examine Intracerebral drain Correct strange INR or low platelets instantly Neurosurgical referral Cerebral Infarct Thrombolysis or prompt antiplatelet treatment

Early indications of dead tissue Loss of isolated strip 14.jpg SW, day 1

Early indications of localized necrosis Effacement of sulci SW, day 1

CT angiogram

Diffusion Perfusion CT

Other tests FBC U&E INR Glucose ECG Carotid Doppler

Thrombolysis

Why?

DH A New Ambition for Stroke A conference report for a National Stroke technique Dec 2008 If 10% of stroke patients in the UK were given thrombolysis, 1000 individuals less would be dead or ward in one year. http://www.dh.gov.uk/en/Publicationsandstatistics/Publications/PublicationsPolicyAndGuidance/DH_081062

NINDS trial of rt-PA for intense ischaemic stroke 633 patients enrolled Rt-PA 0.9 mg/kg (10% bolus the rest more than 1 h) given inside 3 hrs of indication onset BP<185/110 Not on warfarin or heparin, platelets and coagulation ordinary Blood glucose 2.7-22 mmol/L No seizure at onset Quasi escalated mind condition Aggressive BP control 16,000 screened to enlist 633 N Engl J Med 1995;333:1581-1587 .

NINDS rt-PA trial 1995 Improvements in reliance (altered Rankin Scale: mRS) Mean Score 2.8 for rt-PA and 3.3 for control : contrast 0.5 mRS points* Number expected to treat to enhance by 1 point is 2* Number expected to treat to enhance by at least 1 focuses is 3** Number expected to treat to make one patient more autonomous =5* Needs No help Wheelchair Dead Normal INDEPENDENT DEPENDENT * My own estimation bases on the first paper ** Saver. Curve Neurol, Jul 2004; 61: 1066 - 1070.

Eligibility Age 80 or underneath Previously fit and free Onset time known and under 3 hours CT rejects drain

Exclusions Recent surgery, biopsies blood vessel cannulation Increased draining danger Past history of intracranial discharge Any CNS pathology other than current stroke Any past stroke in addition to diabetes Stroke inside 3 months Systolic circulatory strain >185

Alteplase (rt-Pa) 0.9 mg/kg body weight 10% as bolus more than 2 min 90% as imbuement more than 1 hour No heparin for 24 hours

Post thrombolysis Care Needs prepared group/ASU Neurological perceptions (NIHSS) Blood weight Observation for intricacies Scan at 24 h Prevent repeat Early Doppler/CTangio in recuperated cases

The intense stroke pathway How would I be able to ensure my patient will do well?

Most inconveniences of stroke create in the initial 24 hours Management in the initial couple of hours majorly affects result and LOS

Important variables for effective early stroke recovery Mobilize ASAP The likelihood of returning home abatements by 20% for every day the patient is not activated Maintain ordinary haemodynamic and biochemical condition Prevent difficulties Keep patient and family educated

1. Exchange to ASU inside 4 h or less of affirmation

2. Forestall Aspiration Swallow screen on landing on ASU Sit up Drowsy patients in recuperation position Antiememtics for hemorrhages and patients who feel tired All individuals from staff have in any event essential information of the finding and administration of gulping issues

3. Avert hypotension and lack of hydration IV saline Sufficient liquids by mouth or ngt

4. Avert pneumonia Mobilization

Mouthcare Dysphagic patients have disabled oral developments bringing about flotsam and jetsam, pooled emissions and tongue covering.

5. Avert healing center procured diseases MRSA/ESBL/C.Difficile Avoid catheters no matter what Hand cleanliness Bed dispersing Appropriate anti-toxins

6. Avert starvation

7. Avoid stagnation and weakening Time does not cure strokes Give no less than 45 min of every treatment required each day 7/7

7. Recognize and treat issues mid 72 hour observing Neurological scores (NIHSS/SSS) Daily expert ward rounds 7/7
