CCUS had an uncertain effect on duration of mechanical ventilation (MD, 1.14 d fewer; 95% CI, 3.35 d fewer to 1.07 d more; very low certainty), ICU length of stay (LOS) (MD, 0.01 d fewer; 95% CI, 1.12 d fewer to 1.09 d more; very low certainty), the need for vasopressors (RR, 0.39; 95% CI, 0.10-1.62; very low certainty), acute kidney injury (AKI) (RR, 0.94; 95% CI, 0.32-2.72; very low certainty), and the need for renal replacement therapy (RRT) (RR, 0.79; 95% CI, 0.17-3.66; very low certainty).</p><p><strong>Conclusions: </strong>In acutely ill adult patients, CCUS for the use of targeted volume management may reduce mortality and fluid balance up to 72 hours after admission.

Plasma iohexol concentrations were determined by high-performance liquid chromatography and mGFRiohexol was calculated.

There was a strong positive correlation between mGFRiohexol determined with high and low doses of iohexol in patients with normal or high mGFRiohexol (coefficient of determination [R2] = 0.88; p < 0.001) and between mGFRiohexol and uClcr (R2 = 0.87; p < 0.001). eGFRcr overestimated mGFRiohexol and eGFRcys underestimated mGFRiohexol.</p><p><strong>Conclusions: </strong>mGFRiohexol after contrast-enhanced CT compares well with mGFRiohexol after standard low-dose iohexol respectively uClcr.
