Three-Part Question:
In children with stroke [patient], does thrombolysis [intervention] improve mortality and morbidity [outcome]?
Clinical Scenario:
A 4-year-old boy presents in A&E with sudden onset facial paralysis and hemiplegia. CT scan followed by MR angiogram diagnose stroke as a result of thrombosis to Middle Cerebral Artery (MCA). The GP trainee who has worked in Medicine has seen thrombolysis being used in adult patients with stroke. He wonders whether thrombolysis should be carried out for this child.
Search Strategy:
Primary Sources
A search of EMBASE, MEDLINE and PsycINFO healthcare databases (limits: human, English language and Age groups Infant, Preschool Child, Child, School Child and Adolescent) with no publication year limit identified 70 articles.

Search Details:
The following title and abstract/medical subject headings [MeSH] were used: [stroke OR cerebrovascular accident AND thrombolysis OR thrombolysis therapy OR child mortality OR infant mortality OR newborn mortality OR morbidity]
Secondary Sources
No systemic reviews were identified from a search of the Cochrane Library or the NHS Centre for Reviews and Dissemination. Four clinically appraised topics were identified from Up-to-Date and Turning Research into Practice (TRIP) identified 2 guideline statements from the United States and 1 guideline from the UK.

Outcome:
7 case reports were found.4 children showed marked improvement after commencement of thrombolysis. 2 children had neurological sequelae and 1 child showed no improvement at all with complete MCA infarction.There was no specific recommendation of using thrombolysis in children with stroke from the guidelines published by RCP ( Royal College of Physicians), ACCP ( American College of Chest Physicians) and AHA ( American Heart Asoociation)

Author Commentary:
Thrombolysis is routinely used in adult stroke patients who present early.Currently there is no clear guideline available for the management of acute stroke and secondary prevention in paediatrics.
To evaluate the use of thrombolysis in children with stroke; Amlie-Lefond, C et al have proposed an international multicentre study called TIPS (Thrombolysis in Pediatric Stroke).The study will recruit 48 patients from 30 centres.Perhaps this study will enable to highlight the need for developing a consensus guideline for using thrombolysis in children with stroke.

Bottom Line:
Stroke in children can result in significant morbidity and mortality.Various case reports suggest that thrombolysis is effective in children with stroke.The results from proposed large multicentre trial is going to help the clinicians in deciding the best approach in treating these children.
