Counterpulsation catheter fracture: an unexpected hazard
The Annals of Thoracic Surgery
|March 1, 1977
Summary
Intraaortic balloon pump catheters can fracture from chemical damage by acetone during removal. Avoid common hospital chemicals like acetone and ether near polyurethane catheters to prevent this hazard.
Area of Science:
- Cardiovascular Medicine
- Biomaterials Science
Background:
- Intra-aortic balloon pumping (IABP) is a critical mechanical circulatory support device.
- Catheter integrity is paramount for patient safety during IABP procedures.
Observation:
- A previously unrecognized hazard of IABP catheter removal was identified.
- Chemical damage to polyurethane catheters by common hospital agents was observed.
Findings:
- Acetone, a common chemical used during catheter removal, can cause significant chemical damage to polyurethane IABP catheters, leading to fracture.
- Other agents like ether and Vi-Drape spray may also pose a risk.
- Isopropyl alcohol, Betadine, benzoin, and Cidex were found to be safe for contact with these catheters.
Implications:
- Healthcare professionals must be aware of the risk of catheter fracture due to chemical interactions.
- Revised protocols for IABP catheter removal and maintenance are necessary to prevent device failure.
- Material compatibility studies are crucial for medical device development and clinical use.
