Insights

Enoxaparin effectively treats arterial thrombosis in infants with congenital heart disease. This study found it safe and efficient, with 91% thrombosis resolution and minimal bleeding complications.

Area of Science:

  • Pediatric Cardiology
  • Neonatal Thrombosis Management
  • Pharmacology

Background:

  • Catheter-related arterial thrombosis is a serious complication in infants with congenital heart disease.
  • Current treatment often involves unfractionated heparin, but alternatives are being explored.

Purpose of the Study:

  • To evaluate the efficacy and safety of enoxaparin in treating catheter-related arterial thrombosis in infants with congenital heart disease.

Main Methods:

  • A prospective observational study was conducted in a pediatric intensive care and cardiology unit.
  • 32 infants (0-12 months) with catheter-related arterial thrombosis received enoxaparin.
  • Dose requirements, thrombosis resolution via Doppler ultrasound, and bleeding complications were assessed.

Main Results:

  • Complete resolution of thrombosis occurred in 91% of infants within a mean of 23 days.
  • Newborns required higher enoxaparin doses than older infants to achieve therapeutic levels.
  • Only one infant (3%) experienced bleeding complications.

Conclusions:

  • Enoxaparin demonstrates high efficacy and safety for treating catheter-related arterial thrombosis in this pediatric population.
  • It may serve as a viable alternative to unfractionated heparin for these patients.

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 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...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

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...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

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...
