Paradoxical Agitation and Masseter Spasm During Propofol Procedural Sedation: A Case Report.

Introduction: Propofol is an anesthetic agent commonly used in emergency department (ED) procedural sedation. It is often preferred in orthopedic procedures because of its muscle-relaxing properties. Rarely, however, it can induce agitation and muscle hypertonicity.

Comparison of Camera-Acquired Vital Signs to Conventional Vital Signs in a Space-Analog Environment.

Introduction: Vital sign acquisition is a key component of modern medical care. In wilderness and space medical settings, vital sign acquisition can be a difficult process because of limitations on available personnel or lack of access to the patient. Camera-acquired vital signs could address each of these difficulties.

Evaluation of N95 respirator ultraviolet decontamination and clinical reuse with quantitative fit testing.

The supply of N95 respirators has been severely strained by the coronavirus disease 2019 (COVID-19) pandemic. We used quantitative fit-testing to evaluate 16 participants and 45 respirators through up to 4 rounds of ultraviolet decontamination and clinical reuse. The mean fit-test failure rate was 29.

Simulation Training for In-Flight Medical Emergencies Improves Provider Knowledge and Confidence.

In-flight medical emergencies require healthcare providers to operate in confined spaces with limited resources and delayed access to definitive care. These emergencies are common, with an estimated frequency of 1 per 100 to 1000 flights. Despite this, training for medical response in these environments is limited.

Emergency department provider and facility variation in opioid prescriptions for discharged patients.

Study Objective: To study the variation in opioid prescribing among emergency physicians and facilities for discharged adult ED patients.

Methods: We conducted a retrospective analysis of ED visits from five U.S.

Horner's Syndrome after Scalene Block and Carotid Dissection.

Background: Horner's syndrome refers to the clinical triad of ptosis, miosis, and anhidrosis resulting from disruption of the ocular and facial sympathetic pathways. A myriad of etiologies can lead to Horner's syndrome; awareness of the underlying anatomy can assist physicians in identifying potential causes and initiating appropriate care.

Case Report: Two patients presented to our Nashville-area hospital in 2014.

Ozone Uptake During Inspiratory Flow in a Model of the Larynx, Trachea and Primary Bronchial Bifurcation.

Three-dimensional simulations of the transport and uptake of a reactive gas such as O(3) were compared between an idealized model of the larynx, trachea, and first bifurcation and a second "control" model in which the larynx was replaced by an equivalent, cylindrical, tube segment. The Navier-Stokes equations, Spalart-Allmaras turbulence equation, and convection-diffusion equation were implemented at conditions reflecting inhalation into an adult human lung. Simulation results were used to analyze axial velocity, turbulent viscosity, local fractional uptake, and regional uptake.
