Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Difference in syndecan 1 plasma concentration (in ng/mL) between pre- and postoperative measurements as a marker for acute glycocalyx damage. Time points: Preoperative (day 0): baseline blood sampling (5 mL + 2 mL citrate plasma); Postoperative (<1h): blood sampling (5 mL + 2 mL) 24h postoperative: blood sampling (5 mL + 2 mL); | — |
Secondary
| Measure | Time frame |
|---|---|
| Concentrations of all markers (syndecan-1, heparan sulfate, hyaluronic acid, thrombomodulin, angiopoietin-2, MMP-2, MMP-9) at all three time points; postoperative organ function (SOFA score); complication rates; length of hospital stay; perioperative vital signs and laboratory values; exploratory analyses of correlations between biomarkers, clinical outcomes, and perioperative parameters. Time points: Preoperative (day 0): baseline blood sampling (5 mL + 2 mL citrate plasma); Postoperative (<1h): blood sampling (5 mL + 2 mL) 24h postoperative: blood sampling (5 mL + 2 mL); | — |
