Rapid fluid resuscitation with central venous catheters
Annals of Emergency Medicine
|March 1, 1983
Summary
Central venous catheters can effectively deliver fluids rapidly to hypovolemic patients. Specific introducer catheters demonstrated superior flow rates compared to peripheral options.
Area of Science:
- Medical Devices
- Emergency Medicine
- Critical Care
Background:
- Hypovolemia requires rapid fluid resuscitation.
- Central venous catheters are potential tools for rapid fluid administration.
Purpose of the Study:
- To evaluate the efficacy of central venous catheters for rapid fluid administration in hypovolemic patients.
- To compare the maximum flow rates of various central and peripheral catheters using water and blood products.
Main Methods:
- Comparative analysis of maximum flow rates for different central and peripheral catheters.
- Testing with water and blood products.
- Evaluation of factors influencing flow rates, such as pressure infusion cuffs and blood warmers.
Main Results:
- USCI 8 and 9 French introducers exhibited the fastest flow rates (P < .05).
- A 12-inch IV extension tubing showed slightly lower flow rates than introducers (P < .05).
- The Deseret Subclavian Jugular Catheter demonstrated significantly slower flow rates.
Conclusions:
- Central venous catheters can serve as effective adjuncts for rapid fluid resuscitation.
- Catheter size and type significantly impact fluid administration rates.
- Factors like pressure infusion and warming can influence flow dynamics.
