Prehospital Flumazenil: Five-Year Review Of Use, Indications, Outcomes, And Adverse Events In Suspected Benzodiazepine Overdose, Cameron G. Hanson, Bryan P. Beaver, Eric Frantz, Thomas Dunn, Stephen Thornton, Isabel Cava, Ryan C. Jacobsen

Student Publications

Introduction: Historically, flumazenil was employed as both a diagnostic aid in unresponsive patients and as an antidote for suspected benzodiazepine overdose in both emergency departments and out-of-hospital settings. However, its prehospital application has been historically constrained by long-standing concerns regarding adverse events, leading many emergency medical service (EMS) systems to restrict or avoid its use. The use of flumazenil in the prehospital setting remains underreported in the literature, despite its inclusion in the treatment protocols of various EMS agencies. We conducted a descriptive analysis of the use of flumazenil by EMS in the out-of-hospital setting across the state of Kansas …

Measuring Maintainable Income Under Natural Capital Depletion: A Dynamic Sustainability-Weighted Cost Of Capital Framework, Khaled Aldhaferi

Journal of King Abdulaziz University: Economics and Administration

Sustainability reporting has improved the visibility of climate, resource, and safety risks, but it still does not provide a measurement mechanism for separating maintainable operating surplus from income generated by depleting finite natural capital. This paper develops Dynamic Sustainability-Weighted Cost of Capital (Dynamic SWACC) as a governed shadow-accounting architecture for estimating sustainability-adjusted maintainable income. The framework begins from the Hicksian capital-maintenance view of income and the El-Serafy user-cost method, derives the user-cost charge from a finite-horizon operating-surplus annuity, and endogenizes the discount rate through auditable state variables: reserve-life constraint intensity, carbon-budget utilization, and operational safety risk. The developed contribution extends …
