"Atropine" AND "Emergency"

Japanese encephalitis virus (JEV) is the leading cause of viral encephalitis worldwide. The emergence of new genotypes of the virus and a high rate of mutation make it necessary to develop alternative treatment strategies against this deadly pathogen. Although the antiviral properties of Atropa belladonna and some of its active components, such as atropine and scopolamine, have been studied, the effect of another important component, hyoscyamine, against JEV infection has not yet been investigated. In this study, we investigated the antiviral effect of hyoscyamine against JEV and its immunomodulatory activity in embryonated chicken eggs...

In this focused update, the American Heart Association provides updated guidance for resuscitation of patients with cardiac arrest, respiratory arrest, and refractory shock due to poisoning. Based on structured evidence reviews, guidelines are provided for the treatment of critical poisoning from benzodiazepines, β-adrenergic receptor antagonists (also known as β-blockers), L-type calcium channel antagonists (commonly called calcium channel blockers), cocaine, cyanide, digoxin and related cardiac glycosides, local anesthetics, methemoglobinemia, opioids, organophosphates and carbamates, sodium channel antagonists (also called sodium channel blockers), and sympathomimetics...

INTRODUCTION: Controversy exists with regard to risk of secondary exposure of health care workers caring for patients who have ingested an organophosphate insecticide. We aim to report clinical effects of staff members caring for an organophosphate poisoned patient. INCIDENT: A 76-year-old male presented to the Emergency Department exhibiting a cholinergic toxidrome requiring atropine, intubation and mechanical ventilation. METHODS: We undertook a retrospective chart review of any Emergency Department presentations for medical assessment in relation to the incident and conducted telephone interviews of any healthcare workers who did not present but were deemed to be closely involved with patient care...

Myopia has significantly risen in East and Southeast Asia, and the pathological outcomes of this condition, such as myopic maculopathy and optic neuropathy linked to high myopia, have emerged as leading causes of irreversible vision loss. Addressing this issue requires strategies to reduce myopia prevalence and prevent progression to high myopia. Encouraging outdoor activities for schoolchildren and reducing near-work and screen time can effectively prevent myopia development, offering a safe intervention that promotes healthier habits...

INTRODUCTION: Although the 2020 American Heart Association (AHA) guidelines recommend that sodium bicarbonate (SB) be avoided during routine cardiopulmonary resuscitation (CPR) a limited number of studies have examined the effects of SB injection during prolonged CPR (>15 min) in prehospital setting. The present study aimed to examine the effects of prehospital SB use during prolonged CPR on patients' outcome. METHODS: In this retrospective cross-sectional study adult patients aged >18 years who experienced a non-traumatic, out-of-hospital cardiac arrest (OHCA) were compared regarding three outcomes, namely return of spontaneous circulation (ROSC), ROSC > 20 minute, and survival to discharge, based on receiving or not-receiving SB during CPR...

Aneurysmal subarachnoid hemorrhage (SAH) is an acute neurologic emergency. We report the case of a 48-year-old male with a massive SAH caused by a ruptured aneurysm of the vertebrobasilar transition. During an urgent craniotomy, due to an aneurysm re-rupture, adenosine was given for flow arrest but no sinus pause was observed. Esmolol was administered and strategies for cerebral protection were implemented. The surgeon was able to clip the aneurysm and the patient was discharged after 78 days without sequelae...

Tropane alkaloids (TAs) have emerged as plant toxins, related to poisoning events. The development of stable antibodies is crucial to ensure the effectiveness of immunological methods in quickly and accurately monitoring these alkaloids. In this study, based on hybridoma, the variable region gene of monoclonal antibody (mAb) was amplified, and the recombinant antibody (rAb) gene sequence (VH-Linker-VL) was successfully constructed and expressed in HEK293F. The obtained rAb has kept the same performance as mAb, and the IC50 of 29 TAs ranged from 0...

BACKGROUND: Functional bradycardia is a challenging condition that affects a healthy population. Ganglionated plexus ablation has emerged as a therapeutic alternative to avoid a pacemaker. OBJECTIVES: The purpose of this study is to evaluate long-term effects of anatomically guided cardiac denervation. METHODS: This is a prospective longitudinal study that included 36 patients with symptomatic functional bradycardia. Electroanatomic reconstruction of both atria was carried out, and the main septal ganglionated plexi were anatomically located and targeted...

UNLABELLED: Nerium oleander is a plant containing cardiac glycosides, and intoxication with its leaves is a medical emergency. We report the case of a 73-year-old man who took a decoction of oleander leaves for a reckless purpose. Upon arrival in the emergency room, he presented an altered state of consciousness, drooling and vomiting. He was bradycardic with intermittent third-degree atrioventricular block and typical downsloping ST-segment depression related to glycosides toxicity. Despite initial treatment with atropine, isoprenaline and repeated bolus of digoxin-specific antibody (Fab) fragments, symptoms were persistent 12 hours after admission...

AUDIENCE: Emergency medicine residents, internal medicine residents, family medicine residents, community physicians, pediatricians, toxicology fellows. INTRODUCTION: There are over 600 compounds which contain anticholinergic properties.1 Medications with anticholinergic properties include antihistamines, atropine, tricyclic antidepressants, antipsychotics, topical mydriatics, antispasmodics, sleep aids, and cold preparations. 1-4 Plants that possess anticholinergic properties such as jimson weed, and street drugs cut with anticholinergics such as scopolamine are sources of accidental or intentional ingestion...

Background Organophosphorus (OP) compound poisoning is the most common toxicological medical emergency in India, where the majority of the population lives on agriculture. The Peradeniya Organophosphorus Poisoning (POP) scale can be a simple and effective system to determine the need for ventilatory support early in the course of admission. The objective of this study was to evaluate the prognostic value of the clinical parameters of the POP scale in predicting the severity of organophosphorus compound poisoning, by comparing early predicted patient prognosis evaluated by the POP scale on admission with the patient outcome...

UNLABELLED: Mad honey contains grayanotoxin, which is commonly derived from the nectar of a few Rhododendron species. It is commonly used by natives of the Himalayas in the belief of its medicinal use. CASE PRESENTATION: The authors report a case of 62 years old male with mad honey poisoning who was presented to the emergency department with loss of consciousness and had bradycardia and hypotension on arrival. The patient received intravenous fluids, atropine, and vasopressor support and was closely monitored in the coronary care unit for 48 h...

Cardiovascular changes following lumbar spine surgery in a prone position are exceedingly rare. Over the past 20 years, a total of six cases have been published where patients experienced varying degrees of bradycardia, hypotension, and asystole, which could be attributed to intraoperative dural manipulation. As such, there is emerging evidence for a potential neural-mediated spinal-cardiac reflex. The authors report their experience of negative chronotropy during an elective lumbar spine surgery that coincided with dural manipulation and review the available literature...

The effectiveness of pharmacologic management of cardiac arrest patients is widely debated; however, several studies published in the past 5 years have begun to clarify some of these issues. This article covers the current state of evidence for the effectiveness of the vasopressor epinephrine and the combination of vasopressin-steroids-epinephrine and antiarrhythmic medications amiodarone and lidocaine and reviews the role of other medications such as calcium, sodium bicarbonate, magnesium, and atropine in cardiac arrest care...

Disseminated intravascular coagulopathy (DIC) is infrequently associated with COVID-19 infection. COVID-19 infection can predispose to thrombotic events through inflammation and microvascular injury. DIC is rarely associated with coronary artery disease, especially myocardial infarction (MI). In this case report, we present an uncommon case of a patient with concurrent DIC and MI in the setting of COVID-19 infection. A 73-year-old male patient with no known cardiovascular risk factor presented with syncope...

PURPOSE: This is the second article in a 2-part series reviewing the pathophysiology and treatment considerations for arrhythmias. Part 1 of the series discussed aspects related to treating atrial arrhythmias. Here in part 2, the pathophysiology of ventricular arrhythmias and bradyarrhythmias and current evidence on treatment approaches are reviewed. SUMMARY: Ventricular arrhythmias can arise suddenly and are a common cause of sudden cardiac death. Several antiarrhythmics may be effective in management of ventricular arrhythmias, but there is robust evidence to support the use of only a few of these agents, and such evidence was largely derived from trials involving patients with out-of-hospital cardiac arrest...

PURPOSE: Rapid-sequence intubation (RSI) is the process of administering a sedative and neuromuscular blocking agent (NMBA) in rapid succession to facilitate endotracheal intubation. It is the most common and preferred method for intubation of patients presenting to the emergency department (ED). The selection and use of medications to facilitate RSI is critical for success. The purpose of this review is to describe pharmacotherapies used during the RSI process, discuss current clinical controversies in RSI medication selection, and review pharmacotherapy considerations for alternative intubation methods...

The recreational and medicinal uses of cannabis are increasing worldwide. Given the recent legalization of marijuana in some regions of the United States, the use of edible formulations has become increasingly popular, especially among the elderly. These new formulations can be up to 10 times more potent than previously available preparations and have been associated with a variety of cardiovascular adverse effects. Here, we present a case of an elderly male who presented with dizziness and altered mental status...
