1 Non-invasive measurement of renal perfusion and oxygen metabolism to predict postoperative acute kidney injury in neonates and infants after cardiopulmonary bypass surgery  F. Neunhoeffer, M. Wiest, K. Sandner, H. Renk, E. Heimberg, C. Haller, M. Kumpf, C. Schlensak, M.

4 Fig 3 Postoperative renal regional oxygen saturation ( r S O 2 ), microcirculation (rFlow), renal oxygen consumption (aRMRO2), and renal resistance index (RRI) in patients after surgical repair without acute kidney injury (AKI; Group 1), patients after surgical repair who developed AKI (Group 2), patients with surgical palliation without AKI (Group 3), and patients with surgical palliation who developed AKI (Group 4). *P-values <0.05 were considered statistically significant. The y-axis does not start at zero; the absolute differences may therefore appear larger than they really are.
