Summary
Central venous catheters are crucial for acute extracorporeal blood purification in renal and non-renal emergencies. Despite advancements, catheter-related complications like infection and thrombosis remain significant challenges requiring optimal care.
Area of Science:
- Nephrology
- Vascular Access
- Critical Care Medicine
Background:
- Central venous catheters (CVCs) are fundamental for acute extracorporeal blood purification.
- Indications include acute renal failure (ARF), end-stage renal disease (ESRD) decompensation, and various non-renal urgent conditions.
Purpose of the Study:
- To review current knowledge on CVC indications, insertion, care, and limitations.
- To provide guidance for optimal CVC use to minimize complications.
Main Methods:
- Review of existing literature on CVCs for extracorporeal therapies.
- Classification of catheters based on duration of use (temporary vs. permanent).
Main Results:
- CVCs are categorized as temporary (<90 days) or permanent (>90 days) based on material and design.
- Despite technical advances, high rates of catheter-related morbidity, including infection and thrombosis, persist.
Conclusions:
- Optimal CVC selection and meticulous care are essential to reduce complications.
- Further research and adherence to best practices are needed to improve patient outcomes.
