Intraoperative Renal Regional Oxygen Desaturation Can Be a Predictor for Acute Kidney Injury after Cardiac Surgery

Objective To evaluate the usefulness of renal regional oxygen saturation (renal rSO2 ) in predicting the risk of acute kidney injury (AKI) after cardiac surgery.

Description
Summary:Objective To evaluate the usefulness of renal regional oxygen saturation (renal rSO2 ) in predicting the risk of acute kidney injury (AKI) after cardiac surgery. Design A prospective observational study. Setting Tertiary care university hospital. Participants One hundred patients undergoing cardiac surgery. Interventions Renal rSO2 was monitored continuously by near-infrared spectroscopy (NIRS) throughout the anesthetic period. Measurements and Main Results Postoperative AKI was defined using the Risk, Injury, Failure, Loss, and End-stage (RIFLE) criteria. Of 95 patients who were included in the final analysis, 34 patients developed AKI after surgery. Recorded renal rSO2 data were used to calculate the total duration of the time when renal rSO2 was below the threshold values of 70%, 65%, 60%, 55%, and 50%. The total periods when the renal rSO2 level was below each of the threshold values were significantly longer in patients with AKI than in those without AKI (p = 0.001 or p
