Insights

Children in pediatric intensive care units (PICUs) face a significant risk of venous thromboembolism (VTE). Central venous catheters (CVCs) are the primary risk factor, leading to increased mortality and longer ICU stays.

Area of Science:

  • Pediatric Critical Care Medicine
  • Hematology
  • Vascular Medicine

Background:

  • Venous thromboembolism (VTE) is a serious complication in critically ill children.
  • Understanding VTE incidence and risk factors in pediatric intensive care units (PICUs) is crucial for patient management.

Purpose of the Study:

  • To determine the incidence and identify risk factors for VTE in children admitted to PICUs.
  • To compare characteristics and outcomes of VTE patients with non-VTE patients.

Main Methods:

  • Prospective observational study conducted in 11 US tertiary care PICUs.
  • Enrolled children with radiographically confirmed VTE over a 6-month period.
  • Collected demographic, patient-related, and outcome data; compared with all PICU admissions.

Main Results:

  • Sixty-six VTE events occurred in 62 of 6653 PICU admissions (0.74% incidence).
  • Strongest risk factors identified: central venous catheter (CVC) use (OR 6.9) and mechanical ventilation (OR 2.8).
  • VTE patients were younger, sicker (higher PIM2 score), had longer ICU stays, and experienced higher mortality (10.2% vs. 2.6%).

Conclusions:

  • Children in PICUs have a substantial risk of VTE.
  • CVC presence is the most significant risk factor for VTE in this population.
  • VTE is associated with poorer outcomes, including increased mortality and prolonged ICU admission.

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 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 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,...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
Pulmonary Embolism I: Introduction01:19

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: 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...
