Insights

Thromboembolism (TE) is a significant complication in children with sarcoma, particularly those with central venous line (CVL) dysfunction. Early identification of risk factors is crucial for managing TE in pediatric sarcoma patients.

Area of Science:

  • Pediatric Oncology
  • Hematology
  • Epidemiology

Background:

  • Thromboembolism (TE) is a serious complication in adult cancer patients.
  • Cancer is a known risk factor for TE in children, but data on pediatric solid tumors is limited.
  • Understanding TE epidemiology in pediatric sarcoma is crucial.

Purpose of the Study:

  • To determine the prevalence and epidemiology of TE in pediatric sarcoma patients.
  • To identify risk factors associated with TE in this population.

Main Methods:

  • Retrospective review of hospital records for children (<=18 years) with sarcoma.
  • Data collected included demographics, sarcoma diagnosis/therapy, and TE diagnosis/management.
  • Statistical analysis using Fisher's exact t-test.

Main Results:

  • 14.3% of pediatric sarcoma patients developed symptomatic TE.
  • Patients with central venous line (CVL) dysfunction had a significantly higher risk (55.5% vs. 8.2%).
  • Higher TE prevalence was observed in older patients, those with metastatic disease, and Ewing sarcoma.

Conclusions:

  • TE is a significant complication in children with sarcoma, especially those with CVL dysfunction.
  • Patients with CVL dysfunction require careful evaluation for TE.
  • Further large prospective studies are needed to define TE epidemiology and risk factors in pediatric sarcoma.

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...

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 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 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...

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...

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,...
