Acute kidney injury appears to be strongly associated with survival in patients undergoing open surgery for aortic dissection, according to a study from Taiwan. Age above 70, cardiogenic shock, preoperative ventilator use, operation at midnight, and longer bypass time also predicted mortality. Hypertension, sepsis, and lower limb malperfusion were independent predictors of acute kidney injury in the analysis.
