Central venous catheter use. Part 2: infectious complications

Area of Science:

• Medical Microbiology
• Infectious Diseases
• Critical Care Medicine

Background:

• Central venous catheters (CVCs) are increasingly utilized in intensive care units (ICUs) and general wards.
• Catheter-related infections are a frequent complication, leading to increased morbidity, mortality, and prolonged hospital stays.
• Risk factors include patient conditions (e.g., malignancy, neutropenia, shock) and treatment factors (e.g., total parenteral nutrition, ICU admission, intubation).

Purpose of the Study:

• To identify key risk factors for central venous catheter colonization and bloodstream infections.
• To evaluate the impact of catheter care, indwelling time, and emerging technologies on infection rates.
• To emphasize the need for comprehensive strategies to reduce CVC-associated infections.

Main Methods:

• Review of existing literature on risk factors and prevention strategies for CVC infections.
• Analysis of patient-related and treatment-related factors contributing to catheter colonization and infection.
• Evaluation of the role of catheter care, dressing types, thrombus formation, and prophylactic measures.

Main Results:

• Prolonged catheter dwell time, lack of aseptic technique during insertion, and frequent catheter manipulation increase infection risk.
• Catheter care quality is paramount; polyurethane dressings may increase colonization risk compared to gauze.
• Thrombus formation elevates infection risk, potentially mitigated by low-dose anticoagulants; antibiotic-impregnated CVCs show promise.

Conclusions:

• Reducing central venous catheter infection rates necessitates a multifaceted approach.
• Strict adherence to guidelines and protocols for CVC insertion, care, and maintenance is crucial.
• Implementation of evidence-based strategies in ICUs and other healthcare settings is essential for patient safety.
