Environmentally sustainable emergency medicine.

Emergency clinicians worldwide are demonstrating increasing concern about the effect of climate change on the health of the populations they serve. The movement for sustainable healthcare is being driven by the need to address the climate emergency. Globally, healthcare contributes significantly to carbon emissions, and the healthcare sector has an important role to play in contributing to decarbonisation of the global economy. In this article, we consider the implications for emergency medicine of climate change, and suggest ways to improve environmental sustainability within emergency departments. We identify examples of sustainable clinical practice, as well as outlining research proposals to address the knowledge gap that currently exists in the area of provision of environmentally sustainable emergency care.

Fournier Gangrene: A Review for Emergency Clinicians.

BACKGROUND: Fournier gangrene (FG) is a rare, life-threatening infection that can result in significant morbidity and mortality, with many patients requiring emergency department (ED) management for complications and stabilization. OBJECTIVE: This narrative review provides an evidence-based summary of the current data for the emergency medicine evaluation and management of FG. DISCUSSION: Although originally thought to be an idiopathic process, FG has been shown to have a strong association for male patients with advanced age and comorbidities affecting microvascular circulation and immune system function, most commonly those with diabetes or alcohol use disorder. However, it can also affect patients without risk factors. The initial infectious nidus is usually located in the genitourinary tract, gastrointestinal tract, or perineum. FG is a mixed infection of aerobic and anaerobic bacterial flora. The development and progression of gangrene is often fulminant and can rapidly cause multiple organ failure and death, although patients may present subacutely with findings similar to cellulitis. Laboratory studies, as well as imaging including point-of-care ultrasound, conventional radiography, and computed tomography are important diagnostic adjuncts, though negative results cannot exclude diagnosis. Treatment includes emergent surgical debridement of all necrotic tissue, broad-spectrum antibiotics, and resuscitation with intravenous fluids and vasoactive medications. CONCLUSIONS: FG requires a high clinical level of suspicion, combined with knowledge of anatomy, risk factors, and etiology for an accurate diagnosis. Although FG remains a clinical diagnosis, relevant laboratory and radiography investigations can serve as useful adjuncts to expedite surgical management, hemodynamic resuscitation, and antibiotic administration.

Intoxicación por monóxido de carbono: una patología poco valorada en urgencias / Carbon monoxide poisoning: an undervalued event in the emergency department

La intoxicación aguda por monóxido de carbono (CO) es una urgencia médica que, de no tratarse oportunamente, puede dejar considerables secuelas neurológicas o incluso provocar la muerte del paciente. El cuadro clínico depende de la intensidad de la exposición a este gas y varía según el grado de afectación de los distintos órganos involucrados. La administración de oxígeno normobárico (NBO) es el tratamiento utilizado en la mayoría de los servicios de urgencias hasta la resolución de los síntomas y la normalización de los niveles de carboxihemoglobina (COHb), siendo dados de alta los pacientes en la práctica común sin seguimiento posterior. Presentamos el caso de un paciente que acude a urgencias por síncope y nos cuestionamos si la utilización de oxigeno hiperbárico (HBO) frente a (NBO) disminuye las secuelas neurológicas, así como la existencia de indicaciones con evidencia científica para su uso (AU)

Carbon monoxide (CO) poisoning is a medical emergency, which if not treated properly could leave considerable neurological sequelae or even cause the death of the patient. The signs and symptoms depend on the intensity of the exposure to the gas and vary according to the degree to which the different organs are affected. Administration of normobaric oxygen (NBO) is the treatment used in most emergency services. This gas is administered until symptoms are resolved and carboxyhemoglobin (COHb) levels have returned to normal. The patient is then discharged with no subsequent follow-up. We present the case of a patient who came to the emergency department due to syncope. We ask ourselves whether the use of hyperbaric oxygen (HBO) compared to NBO decreases neurological sequelae, and if there is scientific evidence for its use in this indication (AU)

The globalization of emergency medicine and its importance for public health.

Emergency medicine (EM) is a global discipline that provides secondary disease prevention and is also a tool for primary prevention. It is a horizontally integrated system of emergency care consisting of access to EM care; provision of EM care in the community and during transportation of patients; and provision of care at the receiving facility or hospital emergency department. EM can offer many tools to improve public health. These tools include primary disease prevention; interventions for addressing substance abuse and interpersonal violence; education about safety practices; epidemiological surveillance; enrolment of patients in clinical research trials focusing on acute interventions; education and clinical training of health-care providers; and participation in local and regional responses to natural and man-made disasters. Public health advocates and health policy-makers can benefit from the opportunities of EM and can help overcome its challenges. Advocating the establishment and recognition of the specialty of EM worldwide can result in benefits for health-care education, help in incorporating the full scope of EM care into the system of public health, and expand the capabilities of EM for primary and secondary prevention for the benefit of the health of the public.

Treating the world without leaving your ED: opportunities to deliver culturally competent care.

When asked about cultural sensitivity, well-meaning, highly educated, and competent physicians admit that while they desire to be culturally sensitive, it is not usually a conscious element of their professional interactions. When it is conscious, they sometimes feel at a disadvantage in their knowledge base or experience. Often physicians are familiar with certain cultural practices but do not know what those practices represent in the lives of their patients; how they produce, exacerbate, or ameliorate illness; and how to function in the patient's best interest within this milieu. In acute clinical encounters, language discordance is by far the most obvious cultural obstacle to providing care. However, increasing exposure to cultural minority populations demonstrates that beyond language, a host of other factors contribute in both obvious and subtle ways to suboptimal care. This report explores some of the challenges faced by immigrant patients and their treating physicians during clinical encounters. It examines the roots of miscommunication and dissatisfaction stemming from cultural differences and expectations and suggests ways to minimize their negative effects.

Emergency medicine in the new South Africa.

A description of recent developments in emergency medicine and prehospital care in the new South Africa is detailed. As South Africa creates a new integrated health care system with equal access for all citizens, expansion of emergency care services to previously disadvantaged populations is occurring. To illustrate current disparities, a comparison of 2 regional systems of emergency medicine is included. The challenges involved and possible future directions in this effort are discussed.

Emergency medicine expeditions to the developing world: the Loma Linda University experience in Papua New Guinea.

Emergency physicians (EPs) are increasingly participating in international medicine in regions that are chronically medically underserved. In August 1994, a ten-member emergency medicine team from the Loma Linda University School of Medicine staffed a 70-bed bush hospital in the primitive highlands of Papua New Guinea, providing both outpatient and inpatient medical care. Typhoid fever, malaria, polio, and numerous other infectious diseases were encountered. Rampant local tribal warfare resulted in regular penetrating injuries from arrows, spears, and machetes. The expedition was judged highly successful, in that 1) substantial medical service was provided to tribespeople accustomed to minimal care, 2) education was provided to local health care providers, and 3) team participants became adept at managing medical conditions uncommon in industrialized societies, and gained valuable ethical and utilitarian perspectives regarding health care delivery in underserved areas. In this article the objectives, organization, and experiences of the team members are described. This information may encourage other EPs to participate in medical expeditions to the developing world, and to provide general principles to assist in their organization and implementation.
