Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

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...

Pulmonary Embolism III: Nursing Management

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

The Periodic Table and Organismal Elements

Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally-occurring, and fewer still are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.The Periodic Table Provides Information about...

Summary

A man intentionally injected mercury intravenously, leading to lung opacities. Treatment with chelating agents and hemodialysis was initiated, but he later developed respiratory symptoms and pleural effusion.

Area of Science:

  • Toxicology
  • Internal Medicine
  • Emergency Medicine

Background:

  • Intravenous mercury administration is rare, often linked to accidental or intentional self-harm.
  • This case involves a suicide attempt via direct injection into the cubital vein.

Observation:

  • The patient presented with alcohol intoxication, localized arm cellulitis, and signs of injection.
  • Initial chest X-ray showed widespread metallic opacities in both lungs, indicating mercury emboli.
  • No immediate respiratory distress was noted.

Findings:

  • The patient received dimercaprol (a chelating agent) and underwent hemodialysis.
  • A month post-initial treatment, the patient developed respiratory symptoms.
  • Follow-up chest X-ray revealed a right pleural effusion, suggesting delayed complications.

Implications:

  • This case highlights the severe systemic consequences of intravenous mercury injection.
  • Prompt medical intervention, including chelation and dialysis, is crucial.
  • Delayed pulmonary complications like pleural effusion can occur, necessitating ongoing monitoring.
