Obtain blood glucose
ABCD score A: age B: blood C: clinical features D:
Duration of
TIA symptoms
Establish ABC's Airway -Breathing: O2 for SpO2< 94%
Circulation: ECG, BP assessment &
IV/Labs (√BG)

,Posterior stroke There are important differences between
posterior and anterior circulation stroke.
The
differences include the value of screening
instruments, optimum diagnostic
modalities, and
clinical features. The face arm speech test
(FAST),
a widely used prehospital stroke
recognition
screening instrument, is less sensitive for
detecting posterior circulation stroke than
for
anterior circulation stroke
, Symptoms of Posterior Circulation Motor deficits (weakness, clumsiness, or
Stroke paralysis
of any combination of arms and legs, up to
quadriplegia, sometimes changing from
one side
to another in different attacks)
"Crossed" syndromes, consisting of
ipsilateral
cranial nerve dysfunction and contralateral
long
motor or sensory tract dysfunction are
highly
characteristic of posterior circulation stroke
Sensory deficits (numbness, including loss
of
sensation or paraesthesia in any
combination of
extremities, sometimes including all four
limbs or
both sides of the face or mouth)
Homonymous hemianopia-a visual field
defect
affecting either the two right or the two left
halves
of the visual fields of both eyes
Ataxia, imbalance, unsteadiness, or
disequilibrium
Vertigo, with or without nausea and
vomiting
Diplopia as a result of ophthalmoplegia
Dysphagia or dysarthria
Isolated reduced level of consciousness is
not a
typical stroke symptom but can result from
bilateral thalamic or brainstem ischaemia
(especially from rostral basilar artery
