Insights

This review updates emergency clinicians on Coronavirus disease 2019 (COVID-19) presentation and evaluation. It covers variants like Delta and Omicron, common symptoms, severe complications, and diagnostic tools for effective patient management.

Area of Science:

  • Emergency Medicine
  • Infectious Diseases
  • Virology

Background:

  • Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, has led to global morbidity and mortality.
  • New variants, including Delta and Omicron, exhibit increased infectivity and impact patient outcomes.
  • While most COVID-19 cases are mild, a significant number of patients, particularly older individuals and those with comorbidities, experience critical illness.

Purpose of the Study:

  • To provide emergency clinicians with a focused update on the clinical presentation of COVID-19.
  • To outline current evaluation strategies for patients with COVID-19 in emergency settings.
  • To highlight key diagnostic and prognostic tools relevant to emergency care.

Main Methods:

  • Review of current literature on COVID-19 presentation and evaluation.
  • Focus on emergency department (ED) specific diagnostic and prognostic approaches.
  • Inclusion of information on various SARS-CoV-2 variants and their clinical implications.

Main Results:

  • Common symptoms include upper respiratory issues, fever, and sensory changes.
  • Extrapulmonary complications can affect cardiovascular, neurologic, gastrointestinal, and dermatologic systems.
  • ED evaluation involves targeted COVID-19 testing, end-organ injury assessment, and judicious use of imaging (radiography, CT, ultrasound).

Conclusions:

  • Emergency clinicians require up-to-date knowledge on COVID-19 presentation and evaluation.
  • Risk scores can aid prognostication but should complement clinical judgment.
  • Comprehensive assessment is crucial for managing diverse COVID-19 presentations and complications.

Introduction Cardiac Emergencies

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
