Insights

Catheter-related venous thrombosis (CRVT) is significantly associated with a history of venous thrombosis, cancer, infection, and multilumina catheters. These findings aid in clinical diagnosis and prevention strategies for CRVT.

Area of Science:

  • Medical research
  • Clinical epidemiology
  • Thrombosis studies

Background:

  • The risk factors for catheter-related venous thrombosis (CRVT) require further elucidation.
  • Understanding CRVT risk factors is crucial for guiding clinical diagnosis and treatment.
  • This study synthesizes existing evidence to identify key CRVT risk factors.

Purpose of the Study:

  • To identify and quantify the risk factors associated with catheter-related venous thrombosis (CRVT).
  • To provide evidence-based guidance for the clinical management and prevention of CRVT.
  • To pool data from existing studies to establish significant predictors of CRVT.

Main Methods:

  • A systematic literature search was conducted across PubMed, Embase, and Cochrane Library up to July 2021.
  • Studies reporting CRVT risk factors were included; reviews, animal experiments, and incomplete data were excluded.
  • Statistical analysis was performed using STATA 15.1 to pool the data.

Main Results:

  • A history of venous thrombosis (OR=3.75), cancer (OR=1.74), infection (OR=2.13), and multilumina catheters (OR=3.34) were significantly associated with increased CRVT occurrence.
  • No significant correlation was found between CRVT and sex, congenital heart disease, bedridden status, sepsis, mechanical ventilation, anticoagulation therapy, or left-sided insertion.
  • Pooled results provide quantitative estimates (odds ratios and confidence intervals) for identified risk factors.

Conclusions:

  • History of venous thrombosis, cancer, infection, and the use of multilumina catheters are identified as significant risk factors for CRVT.
  • Clinical vigilance and targeted preventive measures are recommended for patients with these risk factors.
  • Further research may explore the interplay of these factors in CRVT development.

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 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 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...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

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.

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
