Introduction: The initial management of penetrating ocular injuries is a major sight-threatening problem for both civilian and military medicine. A novel device (Eye-Aid) temporarily tamponades leakage from such injuries while being easy to remove upon arrival to specialized ophthalmologic care. Eye-Aid consists of a protective eye shield with an adhesive backing that connects to a portable canister containing rapidly deployable thermoresponsive foam.

A self-expanding, intraperitoneal deployed, thermoreversible foam has been developed that can be easily administered by a medic in austere settings to temporarily tamponade noncompressible torso hemorrhage. The purpose of this study was to assess the long-term safety and physical characteristics of using Fast Onset Abdominal Management (FOAM; Critical Innovations LLC) in swine.

We sought to determine how resident clinical experience changes based on training level in relation to the patient acuity levels, chief complaints, and dispositions.
Methods: We performed a retrospective chart review of patients seen at a safety-net, academic hospital in Los Angeles from July 1, 2015, to June 30, 2016.
Objective: To compare the efficacy of buccally absorbed prochlorperazine (BAP) to intravenous prochlorperazine (IVP) for the abortive treatment of migraine headaches.
Methods: Randomized double-blind trial. Eighty subjects aged 18-65 presenting with migraines to the ED of a safety-net, urban hospital.
Background: Subdissociative-dose ketamine (SDDK) is used to treat acute pain. We sought to determine if SDDK is effective in relieving acute exacerbations of chronic pain.
Methods: This study was a randomized double-blind placebo-controlled trial conducted May 2017 to June 2018 at a public teaching hospital (ClinicalTrials.
Early, non-clinical studies support the use of hydroxocobalamin to treat sepsis-induced hypotension, but there is no translational, large animal model. The objective of this study was to compare survival in a sepsis model where large swine had endotoxaemia induced with lipopolysaccharide (LPS) and were treated with intravenous hydroxocobalamin (HOC), noradrenaline (NA), or saline. Thirty swine (45-55 kg) were anaesthetized, intubated, and instrumented with continuous femoral and pulmonary artery pressure monitoring.

Pacidose® is an oral medication delivery device that consists of a syringe attached to a tunneled pacifier. This study aimed to determine caregiver and nurse satisfaction and success rate of the Pacidose in the administration of acetaminophen to infants in the pediatric emergency department (ED).

Objective: The purpose of this study is to determine the effectiveness of a simulation-based sexual assault response course for resident physicians at an institution without an on-site SANE program.
Methods: Educational intervention study of 12 emergency medicine residents using a low-fidelity hybrid simulation model.
Objectives: Easily administrated cyanide antidotes are needed for first responders, military troops, and emergency department staff after cyanide exposure in mass casualty incidents or due to smoke inhalation during fires involving many victims. Hydroxocobalamin has proven to be an effective antidote, but cannot be given intramuscularly because the volume of diluent needed is too large. Thus, intraosseous (IO) infusion may be an alternative, as it is simple and has been recommended for the administration of other resuscitation drugs.

Study Objective: Determine the efficacy of intravenous lidocaine when compared to ketorolac for the treatment of acute radicular low back pain.
Methods: Randomized double-blind study of 41 patients aged 18-55 years presenting with acute radicular low back pain.
Study Objective: Hydroxocobalamin is a Food and Drug Administration-approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model.

Methods: The authors performed a multicenter, prospective cohort study involving five emergency departments (EDs) participating in the ToxIC Research Network. Data were collected from May 2009 to December 2011.
Background: Patients sustaining rattlesnake envenomation often develop thrombocytopenia, the etiology of which is not clear. Laboratory studies have demonstrated that venom from several species, including the Mojave rattlesnake (Crotalus scutulatus scutulatus), can inhibit platelet aggregation. In humans, administration of crotaline Fab antivenom has been shown to result in transient improvement of platelet levels; however, it is not known whether platelet aggregation also improves after antivenom administration.

Methods: A retrospective chart review was performed at a tertiary care university-based urban ED located approximately 290 km from the primary site of destruction secondary to an earthquake measuring 9.0 on the Richter Scale and the resulting tsunami.
Background: The rapid development of ascites in a patient without known liver disease is an uncommon occurrence in the Emergency Department. Initial stabilization may include therapeutic peritoneal lavage to reduce diaphragmatic pressure and halt the progression of respiratory compromise. In the absence of liver disease, the differential diagnosis should include a search for malignancy, which has been reported to account for up to 10% of all cases of newly diagnosed ascites.

Methods: Swine were intubated, anesthetized, and instrumented with central arterial and venous lines and a pulmonary artery catheter. Animals (n=36) were randomly assigned to one of 3 groups: hydroxocobalamin alone (150 mg/kg), sodium thiosulfate alone (413 mg/kg), or hydroxocobalamin (150 mg/kg)+sodium thiosulfate (413 mg/kg) and monitored for 60 minutes after the start of antidotal infusion.
Background: Envenomation by crotaline snakes (rattlesnake, cottonmouth, copperhead) is a complex, potentially lethal condition affecting thousands of people in the United States each year. Treatment of crotaline envenomation is not standardized, and significant variation in practice exists.
Methods: A geographically diverse panel of experts was convened for the purpose of deriving an evidence-informed unified treatment algorithm.
Study Objective: In 2005, the Food and Drug Administration approved deferasirox as an oral iron chelating agent for chronic iron overload. To determine usefulness in management of acute iron ingestion, we study the effect of orally administered deferasirox in healthy human adults.
Methods: A double-blinded, placebo-controlled, randomized, crossover study of 8 healthy human volunteers was conducted.
Background: Acute respiratory infection remains a common presentation to Emergency Departments. Oxygen saturations (Sao(2)) may be useful in determining which febrile infants require chest x-rays (CXR) in investigation for bacterial pneumonia (PNA). This study aimed to determine whether Sao(2) is clinically useful in excluding bacterial PNA in febrile infants <24 months.
