Abstract 17: Stroke Alerts in Hospitalized Children
Stroke(2018)
摘要
Introduction: At our institution, the pediatric stroke alert activations started in April 2011 to allow for rapid evaluation and imaging of children presenting within 48 hours with acute stroke symptoms. In a previously published paper, stroke alerts initiated in the pediatric emergency department confirmed strokes in 25% of children. The purpose of this study was to characterize pediatric stroke alerts in hospitalized children. Methods: Demographic and clinical information was obtained from a quality improvement database and medical records for patients (28 days -20 years) at a single institution. Stroke alerts were activated after hospital admission from April 2011 through December 2016. A stroke alert activation means that a neurology resident sees the patient within 15 minutes and MRI is acutely made available. All values were assessed with descriptive statistics. Results: There were 56 in-hospital stroke alerts (mean age 7.5 y, SD 6.1y, 52% male) over 5.75 years. Stroke was the final diagnosis for 25 (45%) children, 72% ischemic, 28% hemorrhage (Figure 1). Other diagnoses included other neurological urgencies including seizure (21%), posterior reversible encephalopathy syndrome (9%), transient ischemic attack (5%) and acute demyelinating encephalomyelitis (4%). Of 25 actual strokes, 68% were stroke alerts initiated by the pediatric ICU or pediatric cardiac ICU. Rapid imaging was completed in 91% of stroke alerts; MRI brain was the 1 st image in 55%. Nine of 25 children with stroke died (36%); 4 secondary to the stroke and the remainder were critically ill prior to stroke diagnosis. Conclusions: Pediatric in-hospital stroke alerts were confirmed stroke in 45% of children, while 38% were other neurological conditions requiring urgent neurologic evaluation. The high frequency of stroke and other serious illnesses in already hospitalized children demonstrates the importance of rapid evaluation via a pediatric stroke alert protocol when stroke is suspected.
