Cardiothoracic & vascular anesthesia
The impact of urine flow on urine oxygen partial pressure monitoring during cardiac surgery
Authors' conclusion
PuO2 measurements were acquired with enough temporal resolution to demonstrate real-time PuO2 monitoring during CPB and the post-CPB period.
Study context
- Population
- Cardiac surgery patients monitored with a novel urinary oxygen monitoring system
- Participants
- 86 patients
- Exposure
- pre-CPB vs cardiopulmonary bypass (CPB) vs post-CPB
- Outcome
- Ability to make real-time intraoperative PuO2 measurements (valid data, given adequate urine flow ≥0.5 ml/kg/hr)
Main finding
As reported in the abstract
Patients included with valid PuO2 data (≤70% data discarded)
CPB vs pre-CPB: P < 0.001 · post-CPB vs pre-CPB: P < 0.001
Observational data: associations, not effects.
Further findings
| Outcome | CPB | post-CPB |
|---|---|---|
| Intervals of discarded data <3 minutes | 96% | 98% |
Median length of discarded data intervals
- Median length <25 s during all periods
- < 25 s
- No significant difference in group median length of discarded data intervals between acute kidney injury (AKI) and non-AKI patients
