Summary
The Capiox E oxygenator with a single blood pump system performs comparably to double pump systems in cardiopulmonary bypass, showing better fluid balance and oxygenation. This study evaluated its effectiveness in routine cardiac surgery.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Medical Device Technology
Background:
- Cardiopulmonary bypass (CPB) requires efficient oxygenators for patient safety.
- Comparing different oxygenator systems is crucial for optimizing surgical outcomes.
- Previous systems often utilized double pump configurations.
Purpose of the Study:
- To evaluate the performance of the Capiox E oxygenator with a single blood pump.
- To compare its efficacy against Maxima and Ultrox oxygenators using double pump systems.
- To assess blood handling, oxygenation, and fluid balance during CPB.
Main Methods:
- An open randomized prospective study involving 90 patients undergoing myocardial revascularization.
- Patients were divided into six groups based on perfusion mode and oxygenator type.
- Laboratory parameters, fluid balance, and oxygenation were monitored before, during, and after CPB.
Main Results:
- Capiox E groups showed lower net fluid input compared to Ultrox and Maxima.
- The Capiox E/NP group had the lowest net fluid balance (p < 0.05).
- Higher FiO2 values were observed in Capiox E groups, though venous saturation was higher in Ultrox/Maxima groups at CPB end.
Conclusions:
- The Capiox E oxygenator with a single blood pump system is comparable to double pump systems (Maxima, Ultrox) for CPB.
- It demonstrates effective blood handling, oxygenation, and fluid balance in routine cardiac surgery.
- This suggests a viable alternative for cardiopulmonary bypass procedures.
