Cardiogenic shock is difficult to diagnose due to diverse presentations, overlap with other shock states (i.e. sepsis), poorly understood pathophysiology, complex and multifactorial causes, and varied hemodynamic parameters. Despite advances in interventions, mortality in patients with cardiogenic shock remains high. Emergency clinicians must be ready to recognize and start appropriate therapy for cardiogenic shock early. ⋯ The emergency clinician should use the clinical examination, laboratory studies, electrocardiogram, and point-of-care ultrasound to aid in the identification of cardiogenic shock. Cardiogenic shock has the potential for significant morbidity and mortality if not recognized early.

The emergent evaluation of children with suspected traumatic cervical spine injuries (CSI) remains a challenge. Pediatric clinical pathways have been developed to stratify the risk of CSI and guide computed tomography (CT) utilization. The cost-effectiveness of their application has not been evaluated. Our objective was to examine the cost-effectiveness of three common strategies for the evaluation of children with suspected CSI after blunt injury. ⋯ A strategy using a clinical pathway to first stratify risk before further diagnostic testing was less costly and more effective than either performing CT scanning or screening cervical radiographs on all patients.
