Summary
Large-bore catheters are vital for intensive treatments but carry risks like infection and thrombosis. Minimizing catheter handling during procedures can help reduce these serious complications.
Area of Science:
- Medical Devices
- Vascular Access
- Patient Safety
Background:
- Large-bore catheters are crucial for intensive medical treatments, including extracorporeal detoxification.
- Increased use of these catheters correlates with a rise in complications such as infection, sepsis, and thrombosis.
Purpose of the Study:
- To investigate the frequency of complications associated with large-bore catheters in hospitalized patients.
- To analyze complication rates based on insertion site and study period.
Main Methods:
- Retrospective analysis of two studies (1979-1990 and 1996-2001) involving 1672 and 182 patients, respectively.
- Examination of complication data from 2626 large-bore and 332 acute catheters.
- Categorization of complications including infection, thrombosis, bleeding, and procedural issues.
Main Results:
- Overall complication rates were 27.7% in the first study and 32.2% in the second study.
- Higher complication rates were observed with subclavian vein catheterization (43.5% and 60.6%) compared to internal jugular vein (23.8% and 20%).
- Common complications included failed punctures, arterial puncture, abscess, septicemia, bleeding, thrombosis, and material defects.
Conclusions:
- Large-bore catheter use is associated with significant complication rates.
- Insertion site (subclavian vs. internal jugular) impacts complication frequency.
- Minimizing catheter handling during hemodialysis or apheresis may reduce complication rates.
