Evaluation of central venous catheter thrombogenicity
Acta Anaesthesiologica Scandinavica. Supplementum
|January 1, 1985
Summary
This study compared central venous catheter thrombogenicity. Polyurethane catheters showed the highest thrombogenicity, while hydromer-coated polyurethane and silicone catheters were least thrombogenic, indicating material choice impacts clot formation.
Area of Science:
- Biomaterials Science
- Medical Device Engineering
- Thrombosis Research
Background:
- Central venous catheters (CVCs) are crucial in medical care but can induce thrombogenicity.
- Understanding the thrombotic potential of different CVC materials is vital for patient safety and device design.
- Existing research lacks comprehensive comparative analysis of various CVC materials' thrombogenicity.
Purpose of the Study:
- To evaluate and compare the thrombogenicity of different central venous catheter materials.
- To determine the extent of platelet deposition and clot formation on various catheter surfaces.
- To correlate in vitro and in vivo findings to identify the least thrombogenic CVC materials.
Main Methods:
- Conducted four studies assessing thrombogenicity of catheter materials.
- Utilized in vitro and in vivo (canine models) experiments measuring platelet deposition using 51-chromium and indium labeling.
- Quantitatively analyzed clot volume and fibrin sheath formation after 2-4 weeks of catheter implantation in canine arteries and veins.
Main Results:
- Polyurethane (PU) emerged as the most thrombogenic material.
- Polyurethane coated with hydromer demonstrated the least thrombogenicity.
- Silicone exhibited the second-lowest thrombogenicity among the tested materials.
Conclusions:
- Catheter material significantly influences thrombogenicity.
- Hydromer-coated polyurethane offers a promising low-thrombogenicity alternative for CVCs.
- Findings provide valuable data for selecting safer CVC materials in clinical practice.

01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

01:28Cardiac 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...
01:30Venous 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...
01:20Venous 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...
01:29Venous 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...
01:30Venous 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,...
