Under pressure: Evaluating the role of intraoperative hemodynamics in postoperative acute kidney injury

In this issue of Journal of Clinical Anesthesia, Wu et al. describe their well-designed randomized trial investigating the impact of targeted mean arterial pressure (MAP) ranges on postoperative acute kidney injury (AKI) [1]. Their study is of pressing concern: postoperative AKI remains a source of shared apprehension among anesthesiologists, surgeons, and nephrologists, for which prevention and treatment strategies are a matter of ongoing debate. The healthcare burden of postoperative AKI is well-described: it is common, costly, and life-threatening.
