  • Cutting Edge Acute Ischemic Stroke Management. Emergency medicine clinics of North America Urdaneta, A. E., Bhalla, P. 2019; 37 (3): 365–79


    Acute ischemic stroke (AIS) is a medical emergency that requires prompt recognition and streamlined work-up to ensure that time-dependent therapies are initiated to achieve the best outcomes. This article discusses frequently missed AIS in the emergency department, the role of various imagining modalities in the work-up of AIS, updates on the use of intravenous thrombolytics and endovascular therapy for AIS, pearls on supportive care management of AIS, and prehospital and hospital process improvements to shorten door-to-needle time.

  • Radiographic and Clinical Predictors of Cardiac Dysfunction Following Isolated Traumatic Brain Injury JOURNAL OF INTENSIVE CARE MEDICINE Urdaneta, A. E., Fink, K. R., Krishnamoorthy, V., Rowhani-Rahbar, A., Vavilala, M. S. 2017; 32 (2): 151-157


    Although cardiac dysfunction after traumatic brain injury (TBI) has been described, there is little data regarding the association of radiographic severity and particular lesions of TBI with the development of cardiac dysfunction. We hypothesize that the Rotterdam or Marshall scores and particular TBI lesions are associated with the development of cardiac dysfunction after isolated TBI.We performed a retrospective cohort study. Adult patients with isolated TBI who underwent echocardiography between 2003 and 2010 were included. A board-certified neuroradiologist assessed the first computed tomography head, assigning the Rotterdam and Marshall scores and the type of TBI. Cardiac dysfunction was defined as either systolic or all cause based on the first echocardiogram after TBI. Demographic, radiological, and clinical variables were used in our analysis.A total of 139 patients were identified, with 20 having isolated systolic dysfunction. The Marshall and Rotterdam scores were not associated with the development of cardiac dysfunction. Only head Abbreviated Injury Scale was found to be an independent predictor of systolic cardiac dysfunction (relative risk: 2.70, 95% confidence interval: 1.19-6.13; P = .02).No specific radiographic variable was found to be an independent predictor of cardiac dysfunction. Further study into clinical or radiological features that would warrant an echocardiogram is warranted, as it may direct patient management.

    Cervical spine injury (CSI) studies have identified different factors contributing to CSI, but none compares the incidence and pattern of injury of patients arriving at the Emergency Department (ED) by private vehicle (PV).We compared the characteristics and injury patterns in CSI patients who were transported to the ED via Emergency Medical Services (EMS) versus PV.We conducted a three-hospital retrospective review of patients with CSI from January 1, 2000 to December 31, 2007. We excluded transfers and follow-up visits. Using a standardized data collection form, we reviewed demographics, mode of transport, mechanism of injury, imaging results, injury type and level, and neurologic deficits. Means and proportions were compared using t-tests and chi-squared as appropriate.Of 1174 charts identified, 718 met all study criteria; 671 arrived by EMS and 47 by PV. There was no difference between groups in age or gender. Ground-level fall was more likely in PV patients (32%, 95% confidence interval [CI] 20-46% vs. 6%, 95% CI 4-9%), whereas motor vehicle collision was less likely (32%, 95% CI 20-46% vs. 67%, 95% CI 63-70%). PV patients more often sustained a stable injury (66%, 95% CI 52-78% vs. 40%, 95% CI 36-44%), and were more often triaged to a lower-acuity area (25%, 95% CI 15-40% vs. 4%, 95% CI 3-6%). The incidence of neurologic deficit was similar (32%, 95% CI 20-46% vs. 24%, 95% CI 21-28%), though more PV patients had spinal cord injury without radiographic abnormality (21%, 95% CI 12-35% vs. 5%, 95% CI 4-7%).A small proportion of patients with CSI present to the ED by PV. Although most had stable injuries, a surprising number had unstable injuries with neurologic deficits, and were triaged to lower-acuity areas in the ED.
