Pediatric stroke pathways can expedite diagnosis. Our goal was to understand the similarities and differences between Canadian pediatric stroke protocols with the aim of optimizing AIS management.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0317167121000275_as2\">\n\t    <jats:title>Methods:<\/jats:title>\n\t    <jats:p>We contacted neurologists at all 16 Canadian pediatric hospitals regarding AIS management. Established protocols were analyzed for similarities and differences in eight domains.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0317167121000275_as3\">\n\t    <jats:title>Results:<\/jats:title>\n\t    <jats:p>Response rate was 100%. Seven (44%) centers have an established AIS protocol and two (13%) have a protocol under development. Seven centers do not have a protocol; two redirect patients to adult neurology, five rely on a case-by-case approach for management. Analysis of the seven protocols revealed differences in: 1) IV-tPA dosage: age-dependent 0.75\u20130.9 mg\/kg (<jats:italic>N<\/jats:italic> = 1) versus age-independent 0.9 mg\/kg (<jats:italic>N<\/jats:italic> = 6), with maximum doses of 75 mg (<jats:italic>N<\/jats:italic> = 1) or 90 mg (<jats:italic>N<\/jats:italic> = 6); 2) IV-tPA lower age cut-off: 2 years (<jats:italic>N<\/jats:italic> = 5) versus 3 or 10 years (each <jats:italic>N<\/jats:italic> = 1); 3) IV-tPA exclusion criteria: PedNIHSS score &lt;4 (<jats:italic>N<\/jats:italic> = 3), &lt;5 (<jats:italic>N<\/jats:italic> = 1), &lt;6 (<jats:italic>N<\/jats:italic> = 3); 4) first choice of pre-treatment neuroimaging: computed tomography (CT) (<jats:italic>N<\/jats:italic> = 3), magnetic resonance imaging (MRI) (<jats:italic>N<\/jats:italic> = 2) or either (<jats:italic>N<\/jats:italic> = 2); 5) intra-arterial tPA use (<jats:italic>N<\/jats:italic> = 3) and; 6) mechanical thrombectomy timeframe: &lt;6 hour (<jats:italic>N<\/jats:italic> = 3), &lt;24 hour (<jats:italic>N<\/jats:italic> = 2), unspecified (<jats:italic>N<\/jats:italic> = 2).<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0317167121000275_as4\">\n\t    <jats:title>Conclusions:<\/jats:title>\n\t    <jats:p>Although 44% of Canadian pediatric hospitals have established AIS management pathways, several differences remain among centers. Some criteria (dosage, imaging) reflect adult AIS literature. Canadian expert consensus regarding IV-tPA and endovascular treatment should be established to standardize and implement AIS protocols across Canada.<\/jats:p>\n\t
