Insights

Central venous line (CVL) dysfunction in children with cancer is linked to increased risks of thromboembolism (TE) and infection. This study aims to prospectively evaluate these associations to improve patient outcomes.

Area of Science:

  • Pediatric Oncology
  • Hematology
  • Vascular Access Devices

Background:

  • Central venous line (CVL) dysfunction is a frequent complication in pediatric cancer patients, often associated with thromboembolism (TE) and infection.
  • Existing research suggests a link between CVL dysfunction, TE, and infection, but prospective studies are lacking.
  • CVL dysfunction has been correlated with reduced overall survival in children with cancer.

Purpose of the Study:

  • To prospectively evaluate the clinical significance of CVL dysfunction in children with cancer.
  • To determine if CVL dysfunction predicts symptomatic TE in this population.
  • To assess the impact of CVL dysfunction on infection rates and patient survival (overall survival and event-free survival).

Main Methods:

  • A prospective, analytical cohort study involving children (≤ 18 years) with non-central nervous system cancers and CVLs.
  • Data collected from five tertiary care pediatric oncology centers in Ontario.
  • Primary outcome: symptomatic TE. Secondary outcomes: infection, cancer recurrence, and all-cause mortality. Analysis via regression.

Main Results:

  • This section is not available in the provided abstract.

Conclusions:

  • CVL dysfunction is hypothesized to increase TE risk through coagulation system activation.
  • CVL dysfunction may promote infection by harboring occult clots, serving as a microbial focus.
  • Identifying high-risk children can inform trials for prophylactic therapies to reduce TE and infection, ultimately improving outcomes.

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...

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,...
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.
Assessment of the Cardiovascular System III: Palpation01:27

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
