Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

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...
Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
Venous Thrombosis IV: Nursing Management01:30

Venous Thrombosis IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Summary

Pediatric thromboembolic disease, including arterial and venous thromboembolism, requires greater awareness. Improved recognition and management of deep venous thrombosis and pulmonary embolism in critically ill children can enhance outcomes.

Area of Science:

  • Pediatric critical care medicine
  • Hematology
  • Vascular medicine

Background:

  • Thromboembolic disease, encompassing arterial and venous thromboembolism, deep venous thrombosis, and pulmonary embolism, presents significant risks in children.
  • Risk factors for thrombosis are particularly concerning in the pediatric intensive care unit (PICU) setting.

Purpose of the Study:

  • To review the epidemiology of pediatric thromboembolic events.
  • To identify risk factors for thrombosis in critically ill children.
  • To summarize diagnostic techniques and current management/prevention strategies for pediatric thromboembolic disease.

Main Methods:

  • Comprehensive literature review utilizing PubMed with keywords related to thromboembolism.
  • Inclusion of both pediatric and adult studies, with a focus on critically ill patients.
  • Synthesis of available data, including adult and institutional experience, due to limited pediatric-specific research.

Main Results:

  • Data on pediatric thromboembolism, including epidemiology and risk factors, were compiled.
  • Diagnostic modalities for arterial/venous thromboembolism were assessed.
  • Current recommendations for management and prevention were summarized, often referencing adult data when pediatric data were scarce.

Conclusions:

  • There is a critical need to increase awareness among pediatric intensivists regarding the recognition and management of thromboembolic disease in children.
  • Enhanced understanding and timely intervention are essential to improve outcomes for life-threatening thromboembolic events in critically ill children.
