    Pediatric stroke is a rare disorder with a paucity of evidence-based treatment options, and can result in significant morbidity and mortality. In contrast to adult acute ischemic stroke, where the use of recombinant tissue plasminogen activator (rt-PA) has been studied in several large, randomized clinical trials, no high-level evidence exists for the use of thrombolytics in children with stroke. We report a case of a 15-year-old girl who suffered an acute ischemic stroke and had a dramatic improvement in symptoms following the administration of intravenous rt-PA.

    Objective: The Canadian Emergency Cardiac Care Coalition, the American Heart Association and similar groups have established a benchmark for the administration of thrombolytics in acute myocardial infarction (AMI) care as a door-to-needle (DTN) time of 30 minutes or less. Previous research suggests that this goal is not being achieved in Canada. The purpose of this study was to determine whether the target DTN time of 30 minutes or less for thrombolysis could be met in 2 rural Ontario emergency departments (EDs).
    Methods: We conducted a retrospective chart review and obtained descriptive data for each case, including demographic information and the Canadian Emergency Department Triage and Acuity Scale (CTAS) score. Visit timeline data were also collected and included the time during which patients saw a physician, had an electrocardiogram (ECG), received thrombolytic therapy and were discharged from the ED. Relevant time intervals, such as the median DTN time, were calculated.
    Results: A total of 454 charts were reviewed for patients with a diagnosis of AMI who were seen between 1996 and 2007. The final sample consisted of 101 patients who received thrombolytics (63% men) whose median age was 67 years and median CTAS score was Level II (Emergent). The median door-to-ECG time was 6 minutes, door-to-physician time was 8 minutes and DTN time was 27 minutes; 58% of patients received thrombolytics within 30 minutes.
    Conclusion: A DTN time of 30 minutes or less is achievable in rural EDs.

  • Neurologically normal survival after fibrinolysis during prolonged cardiac arrest: case report and discussion
    January 2003 5 1

    Cardiac arrest secondary to pulmonary embolism is a devastating condition with a high mortality rate. It is currently unclear whether fibrinolysis (thrombolysis) is beneficial in this setting. We report the case of a 28-year-old woman with a pulmonary embolism who developed return of pulses following the administration of tissue plasminogen activator after 38 minutes of pulseless electrical activity cardiac arrest. She went on to make a full neurologic and cardiopulmonary recovery. This case is discussed with reference to the current literature on the subject.
