Heat Stroke in Emergency Department: Diagnosis and Management

Background: Heat stroke is a severe health concern with the potential for multi-organ failure, necessitating rapid and effective management. With rising global temperatures, there is increasing concern regarding the vulnerability of populations in high-heat areas, notably in Saudi Arabia, especially during the annual Hajj pilgrimage. Objective: This paper aims to review the epidemiology, evaluation and management techniques of heat stroke, emphasizing the situation during Hajj pilgrimages in Saudi Arabia, and to outline the best practices for emergency management. Methodology: A comprehensive review of literature and studies related to heat stroke, both globally and specific to Saudi Arabia, was undertaken. An in-depth analysis of emergency management, including initial assessment, cooling methods, organ support, medication, and prevention strategies, was conducted. Results: Heat stroke remains a significant cause of emergency department visits, with specific groups, such as men and the elderly, being more susceptible. During the Hajj in 2016, 267 patients were diagnosed with heat-related illnesses, with heatstroke accounting for 29% of these cases. With the threat of global warming, studies indicate a potential tenfold increase in heat stroke risk with a 2°C rise in temperatures. Swift and comprehensive cooling is pivotal for recovery. Management emphasizes rapid recognition, assessment, and varied cooling methods, along with targeted treatments for organ dysfunctions. Prevention strategies play a vital role, given the higher efficacy and practicality over treating organ dysfunctions. Conclusion: Heat stroke is a pressing health challenge, particularly in high-risk environments like Saudi Arabia during the Hajj pilgrimage. While effective emergency management protocols exist, an emphasis on prevention is crucial. It is imperative to incorporate a comprehensive approach to address both the immediate threat and long-term risks of heat stroke, especially with the looming challenge of global warming

Acute Subdural Hematoma Management in the Emergency Department

Acute subdural hematoma (ASDH) is a serious and potentially life-threatening condition that requires prompt and effective management in the emergency department (ED). This review article aims to provide an overview of the current evidence-based management strategies for ASDH in the ED setting. The article begins by discussing the pathophysiology of ASDH, emphasizing the rapid accumulation of blood between the dura mater and the arachnoid membrane following a traumatic brain injury. This can lead to increased intracranial pressure and potentially fatal brain herniation if not promptly addressed. The review then outlines the initial assessment and resuscitation of patients with suspected ASDH in the ED. The article then delves into the specific management strategies for ASDH in the ED, including the role of neurosurgical consultation, and the potential need for emergent surgical intervention to evacuate the hematoma and relieve pressure on the brain. In conclusion, this review article provides a comprehensive overview of the current evidence-based management of ASDH in the ED, emphasizing the importance of prompt recognition, accurate diagnosis, and timely intervention to optimize patient outcomes

CARDIOGENIC PULMONARY EDEMA IN CRITICAL CARE

The pathobiology and classification of pulmonary edoema are more complex than the previous dichotomy of hydrostatic vs. permeability. The mechanisms of alveolar fluid clearance and the factors that influence the clearance rate are being studied thoroughly in order to develop therapeutic strategies. Patients require early oxygenation and ventilation stabilization, preferably with high-flow nasal cannula oxygen or noninvasive ventilation, while the diagnostic cause is quickly sought with echocardiography and other testing. Treatments must begin as soon as possible while evaluation continues and requires multimodal intervention. Diuretics, possibly morphine, and frequently nitrates, are used to treat cardiogenic pulmonary edema. This review summarizes current knowledge of the pathophysiology, causes, and treatment of cardiogenic pulmonary edema

Nonsteroidal Anti-inflammatory Drug (NSAID) Toxicity in Emergency Room

Nonsteroidal anti-inflammatory medicines, collectively referred to as NSAIDs in academic context, exhibit chemical diversity while concurrently manifesting comparable therapeutic and harmful effects. All pharmaceutical substances under this particular category function by diminishing inflammation, alleviating pain, and reducing fever by means of inhibiting enzymes responsible for the creation of endoperoxides, often referred to as cyclooxygenase (COX) enzymes. The two cyclooxygenase isozymes, COX-1 and COX-2, are responsible for the conversion of arachidonic acid into its endoperoxide metabolites. These metabolites include prostacyclin, prostaglandins, and thromboxane, each exhibiting a wide range of biological activities such as inflammation, regulation of smooth muscle tone, and promotion of thrombosis. The COX-1 enzyme is consistently produced and is recognized as the main provider of prostanoids required for maintaining physiological balance, such as safeguarding the stomach epithelium. In contrast, the COX-2 enzyme is capable of being induced, leading to a substantial increase in the synthesis of prostanoids in circumstances characterized by stress and inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) may induce toxicity via the same pharmacological mechanisms that contribute to their therapeutic efficacy. This review aims to discuss NSAIDs toxicity in details, its symptoms, and possible management in the emergency room

BLOOD TRANSFUSION REACTION IN EMERGENCY DEPARTMENT

Early detection, rapid cessation of the transfusion, early consultation with the hematologic and ICU departments, and fluid resuscitation are all necessary for the initial management of blood transfusion reactions. It is crucial that doctors stay current with the literature, are knowledgeable of the pathophysiology, early therapy, and hazards of each type of transfusion reaction because blood transfusions can result in major adverse consequences. Immune-mediated transfusion responses frequently result from a mismatch or incompatibility between the recipient and the transfused substance. Monitoring the patient's respiration rate, blood pressure, temperature, and pulse rate is necessary. Abnormal clinical characteristics, such as fever, rashes, or angioedema, should also be constantly evaluated
