The i-gel supraglottic airway device compared to endotracheal intubation as the initial prehospital advanced airway device: A natural experiment during the COVID-19 pandemic.

Objective: Unlike randomized controlled trials, practical real-world studies can offer important information about implementation of prehospital interventions, particularly in community settings where there may be reluctance to adopt new practices. We present the results of a natural experiment that was driven by mandated COVID-19 pandemic-driven shift from endotracheal intubation (ETI) to the i-gel supraglottic airway (SGA) as a primary advanced airway management device in the prehospital setting to reduce emergency medical services (EMS) personnel exposure to potentially infectious secretions. The objective was to compare first-pass success and timing to successful airway placement between ETI and the i-gel SGA under extenuating circumstances.

The A to E (ABCDE) Pit Crew Model: A Novel Approach to Team Based Care of Critical Patients in the Prehospital Setting.

Background: This study aimed to evaluate the effectiveness of a Pit Crew intervention to improve team dynamics and time to performance of critical actions in a prehospital critical care scenario. The primary outcome was successful completion of critical actions and time to completion of these critical actions. Secondary outcomes included effectiveness of communication and overall team functioning.

Evaluation of Glial and Neuronal Blood Biomarkers Compared With Clinical Decision Rules in Assessing the Need for Computed Tomography in Patients With Mild Traumatic Brain Injury.

Importance: In 2018, the combination of glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase (UCH-L1) levels became the first US Food and Drug Administration-approved blood test to detect intracranial lesions after mild to moderate traumatic brain injury (MTBI). How this blood test compares with validated clinical decision rules remains unknown.

Objectives: To compare the performance of GFAP and UCH-L1 levels vs 3 validated clinical decision rules for detecting traumatic intracranial lesions on computed tomography (CT) in patients with MTBI and to evaluate combining biomarkers with clinical decision rules.

Bystander CPR occurrences in out of hospital cardiac arrest between sexes.

Background: Bystander CPR (B-CPR) is known to be a critical action in treating out-of-hospital cardiac arrest (OHCA). Immediate CPR may double a patient's chance of survival. Only 40% of OHCA patients receive B-CPR (Cardiac Arrest Registry to Enhance Survival).

Unnecessary emergency medical services transport associated with alcohol intoxication.

Objective This study investigated medically unnecessary emergency medical services (EMS) transportation by comparing non-intoxicated versus intoxicated patients who did not receive emergency department (ED) treatment but utilized EMS transport. Methods Patients who used EMS but did not receive ED treatment were classified into non-intoxicated and intoxicated groups. Reasons for not receiving ED treatment were categorized according to whether the decision was made by the patient against medical advice or if the decision was based on a physician's evaluation and their recommendations.

Association between EMS Question Bank Completion and Passing Rates on the EMS Certification Examination.

Introduction: A board review question bank was created to assist candidates in their preparation for the 2015 EMS certification examination. We aimed to describe the development of this question bank and evaluate its successes in preparing candidates to obtain EMS subspecialty board certification.

Methods: An online question bank was developed by 13 subject matter experts who participated as item writers, representing eight different EMS fellowship programs.

Trauma Simulation Training Increases Confidence Levels in Prehospital Personnel Performing Life-Saving Interventions in Trauma Patients.

Introduction. Limited evidence is available on simulation training of prehospital care providers, specifically the use of tourniquets and needle decompression. This study focused on whether the confidence level of prehospital personnel performing these skills improved through simulation training.

Evaluation of an off-the-shelf mobile telemedicine model in emergency department wound assessment and management.

We examined the agreement between a videoconference-based evaluation and a bedside evaluation in the management of acute traumatic wounds in an emergency department. Adult and paediatric patients with acute wounds of various severities to the face, trunk and/or extremities presenting to the emergency department within 24 hours of injury were enrolled. Research assistants transmitted video images of the wound to an emergency physician using a laptop computer.

A comparison of tele-education versus conventional lectures in wound care knowledge and skill acquisition.

We conducted a randomized controlled study to compare conventional lectures with tele-education for delivering wound care education. Education was delivered by the two methods simultaneously to two classes. Forty-eight paramedics received a live didactic presentation and 41 paramedics received the same lecture via videoconferencing.

Effects on cytokines and histology by treatment with the ACE inhibitor captopril and the antioxidant retinoic acid in the monocrotaline model of experimentally induced lung fibrosis.

Monocrotaline (MCT), a pyrrolizidine alkaloid extracted from the shrub Crotalaria spectabilis, induces in the lungs of many mammalian species severe hypertension and fibrosis. Previous work with MCT-induced lung disease in rats has shown that some of the steps to progressive fibrosis can be interrupted or decreased by intervention with retinoic acid (RA) or with the angiotensin converting enzyme inhibitor, captopril. This report emphasizes the pathology and cytokines present in lungs of rats in the MCT model of hypertension and fibrosis in 8 treatment groups, six per group: (1) controls, not treated; (2) captopril; (3) RA; (4) combined captopril and RA.
