Renal Failure Clinical Trial
— ValiVexusOfficial title:
External Validation of the VExUS Score for the Prediction of Acute Renal Failure in Cardiac Surgery
Acute renal failure is a frequent complication associated with significant morbidity and mortality in postoperative cardiac surgery. The VExUS (Venous Excess UltraSound grading system) score was created to qualitatively assess this venous congestion, based on ultrasound data from patients obtained post operatively in cardiac surgery. These data included: inferior vena cava diameter, Doppler flow of the suprahepatic veins, portal trunk and renal veins. This score is predictive of the onset of acute renal failure in the first 3 days after surgery. The VExUS score has not been validated in an external and prospective way in cardiac surgery.

Primary | Association between the change in ultrasound data collected in the VExUS score and postoperative acute renal failure (defined by a creatininemia increase by 26.5 µmol/L in 48 hours). | correlation between operator in term of VExUS staging (VExUS score will be assessed at day 1, 2 and 3 after the surgery, in intensive care unit. | From date of randomization until date of post-operative acute renal failure (detected by daily creatininemia), assessed up to a variable period of time estimated to 2 weeks. | |
Primary | Association between the change in ultrasound data collected in the VExUS score and postoperative acute renal failure. | Specificity of the VExUS score to predict an acute kidney failure will be evaluated | From date of randomization until date of post-operative acute renal failure (detected by daily creatininemia), assessed up to a variable period of time estimated to 2 weeks | |
Secondary | Correlation between the VExUS score and a postoperative acute renal failure | Use of a multivariable COX regression to evaluate the correlation between the VExUS score measured at day 1, 2 and 3 and a post-operative acute renal failure during the stay in intensive care unit | 3 days | |
Secondary | Diagnostic performances of the VExUS Score for postoperative acute renal failure | Sensitivity, NPV, PPV | 3 days | |
Secondary | Correlation between central venous pressure (CVP) and postoperative acute renal failure. If a statistical association is present, diagnostic performance (Sensitivity, Specificity, NPV, PPV) of the value | Central venous pressure (CVP). The values will be taken during the ultrasound scans at Day 0, Day 1 and Day 2. The units of pressure are mmHg. A value greater than 12mmHg will be considered high, a lower value as not high. The CVP is measured by a central venous line. | 3 days | |
Secondary | Correlation between daily fluid balance and postoperative acute renal failure. If a statistical association is present, diagnostic performance (Sensitivity, Specificity, NPV, PPV) of the value | Water balance: 24-hour input-output balance, in millilitres, collected daily. Values measured at Day 0, Day 1, Day 2 | 3 days | |
Secondary | Correlation between daily fluid balance and postoperative acute renal failure. If a statistical association is present, diagnostic performance (Sensitivity, Specificity, NPV, PPV) of the value | Water balance: including the weight in Kg compared to the reference weight established during the anaesthetic consultation.
