Hypothesis
Can delta central venous pressure (δCVP) improve the accuracy of pulse pressure variation (PPV) and stroke volume variation (SVV) in predicting fluid responsiveness?
Conclusion
The study found that using δCVP does not improve the efficacy of SVV and PPV in predicting fluid response.
Supporting Evidence
- Forty-nine patients were monitored to assess fluid responsiveness.
- Eighty-two fluid challenges were performed during the study.
- 33% of patients in group A responded to fluid challenges compared to 36% in group B.
Takeaway
Doctors wanted to see if a new measurement could help them know when patients need more fluids, but it didn't make a difference.
Methodology
Forty-nine fully ventilated patients were monitored postoperatively, and fluid challenges were performed to assess fluid responsiveness.
Limitations
More patients are needed to fully understand the relationship between δCVP and the best cut-off values for SVV and PPV.
Participant Demographics
Fully ventilated patients in sinus rhythm admitted postoperatively to the ICU.
