Central vs peripheral venous catheters in critically ill patients
Chest
|December 1, 1986
Summary
Centrally inserted central catheters show lower morbidity than peripheral intravenous catheters in intensive care units. Maintaining high-level insertion technique supervision is crucial for central catheter safety.
Area of Science:
- Critical Care Medicine
- Vascular Access Devices
- Infection Control
Background:
- Intravenous (IV) catheters are essential in intensive care units (ICUs).
- Catheter-related complications, including phlebitis and infections, pose significant risks.
- Optimizing IV catheter use requires understanding insertion site and type impact on morbidity.
Purpose of the Study:
- To compare morbidity associated with different types of IV catheters.
- To identify insertion sites with the least complications.
- To determine reasons and timing for catheter removal.
Main Methods:
- Prospective study of 2,209 intravenous catheters in a multidisciplinary ICU.
- Vigorous supervision of insertion techniques.
- Identical care protocols for central and peripheral catheters.
- Data collection on catheter removal, insertion sites, and complications.
Main Results:
- Overt phlebitis was 14 times more common with peripheral catheters (353/1,024) than centrally inserted central catheters (18/713).
- Centrally inserted central catheters had a longer average dwell time (6.2 days) compared to peripheral catheters (2.9 days).
- Pneumothorax occurred in 7/713 central catheterizations; suppurative thrombophlebitis in 3/1,496 peripheral/peripherally inserted central catheterizations.
Conclusions:
- Centrally inserted central catheters are associated with lower overall morbidity in critically ill patients compared to peripheral IV catheters.
- Peripherally inserted central catheters represent an intermediate option regarding morbidity.
- High-level supervision of insertion techniques is vital for minimizing central catheterization complications.
