The US military experience with THAM.

Background: Acidosis, a part of the lethal trauma triad, occurs frequently after major combat trauma. Tris-hydroxymethyl aminomethane (THAM) has been used to effectively treat acidosis in injured casualties. No research has been conducted assessing the safety of THAM in the military combat setting.

The THINK (Treatment of Headache with Intranasal Ketamine) Trial: A Randomized Controlled Trial Comparing Intranasal Ketamine with Intravenous Metoclopramide.

Background: Headache is a common chief complaint in the emergency department (ED) setting.

Objectives: To compare analgesia with metoclopramide and diphenhydramine vs. intranasal ketamine among ED patients with primary headache.

An uncommon cause of vision loss: Leber hereditary optic neuropathy.

Leber hereditary optic neuropathy (LHON) is a rare mitochondrial genetic disorder characterized by painless acute or subacute vision loss that develops during adolescence. Clinicians should know how to identify potential LHON and when to refer patients to a neuro-ophthalmologist for diagnosis and treatment. This case highlights the value of a thorough family history in ED patients.

Association between seatbelt sign and internal injuries in the contemporary airbag era: A retrospective cohort study.

Background: Literature predating routine availability of airbags reported an association between seatbelt signs and internal injuries. We measured this association among patients involved in motor vehicle crashes (MVCs) with airbag deployment.

Methods: We conducted a retrospective cohort study by chart review of all MVC patients presenting to our Emergency Department (ED) during 1 January 2008-30 September 2015.

Single Rescuer Ventilation Using a Bag Valve Mask with Removable External Handle: A Randomized Crossover Trial.

Unlabelled: Introduction Ventilation with a bag valve mask (BVM) is a challenging but critical skill for airway management in the prehospital setting. Hypothesis Tidal volumes received during single rescuer ventilation with a modified BVM with supplemental external handle will be higher than those delivered using a standard BVM among health care volunteers in a manikin model.

Methods: This study was a randomized crossover trial of adult health care providers performing ventilation on a manikin.

Single rescuer ventilation using a bag-valve mask with internal handle: a randomized crossover trial.

Objective: To compare tidal volume received during single rescuer ventilation with a modified bag-valve mask (BVM) with integrated internal handle vs standard BVM among healthy volunteers using a manikin model.

Methods: This study was a randomized crossover trial of adult healthcare provider volunteers performing ventilation on a manikin. We randomized participants to perform single rescuer ventilation first using either a modified BVM with integrated internal handle or a standard unmodified BVM.
