Emergency endotracheal intubation-related cardiac arrest (CA) is not well documented. This study compares the clinical features and outcomes of intubation-related CA and other causes of inhospital CA. ⋯ Endotracheal intubation-related CA occurred higher than commonly recognized, and patient outcomes were not better than other causes of CA. These data highlight the importance of efforts to prevent intubation-related CA. However, further prospective larger study will be required to generalize this result.

The inferior vena cava (IVC) parameters, including its diameter and collapsibility index have been evaluated for fluid status for over 30 years, but little is known about the impacts of patient characteristics on IVC parameters. The purpose of this study was to explore the relationships between individual patient characteristics and IVC parameters in healthy Chinese adult volunteers. ⋯ The percentage collapse of IVC and the IVCmax are not substantially influenced by patient characteristics. In contrast, the IVC/Ao index is more susceptible to patient characteristics than IVC.

Our objectives were to determine the frequency of patient transfers to a tertiary care emergency department (Tertiary ED) due to a lack of radiology services in rural hospital EDs (Rural EDs), and examine the community and patient attributes that are associated with these transfers. ⋯ Lack of radiology services in Rural EDs leads to numerous patient transfers to the Tertiary ED each year. A disproportionate number of these transfer patients are African American. These transfers place additional financial and social burdens on patients and their families. This study discusses these findings and alternative diagnostic options (ie, telemedicine and ultrasound video transfer) to address the lack of radiology services available in Rural EDs. The use of these alternate diagnostic options will likely reduce the number of patient transfers to Tertiary EDs.

Cerebral oximetry with cerebral blood volume index in detecting pediatric stroke in a pediatric ED.
Despite pediatric stroke awareness and pediatric stroke activation systems, recognition and imaging delays along with activation inconsistency still occur. Reliable objective pediatric stroke detection tools are needed to improve detection and activations. Regional cerebral oxygen saturation (rcso2) with cerebral blood volume index (CBVI) can detect abnormal cerebral physiology. ⋯ Cerebral oximetry and CBVI detected abnormal cerebral physiology, stroke location, and type (hemorrhagic or ischemic). Rcso2 side differences greater than 10 or rcso2 readings less than 50% had a 100% positive predictive value for stroke. Cerebral oximetry has shown potential as a detection tool for stroke location and type in a pediatric stroke alert and nonalert stroke patients. Using cerebral oximetry by the nonneurologist, we found that the patient's rcso2 side difference greater than 10 or one or both sides having less than 50% rcso2 readings suggests abnormal hemispheric pathology and expedites the patient's diagnosis, neuroresuscitation, and radiologic imaging.

The aim of this study was to assess the outcomes, incidental findings, recommendations, and adherence to recommendations on computed tomography angiography (CTA) studies obtained in the emergency department (ED) to evaluate for aortic dissection. ⋯ Computed tomography angiography is useful in detecting aortic pathology. However, emergency physicians should be aware of the potential for clinically significant incidental findings and recommendations. Adherence to recommendations was limited, and future research could investigate mechanisms to improve compliance.
