Welcome back to Niko’s Perioperative.

Because staying curious makes all the difference!

In this episode, we take a dive into the evolving world of Acute Kidney Injury (AKI) in anesthesiology. We explore the monumental changes and advancements that have occurred since the game-changing 2012 KDIGO guidelines were released.

Throughout our conversation, we uncover the potential of cutting-edge biomarkers to revolutionize the early detection and management of AKI, offering us unprecedented insights into this critical condition. We navigate the ongoing controversies in fluid management—debating crystalloids; balanced solutions vs. normal saline, and restrictive vs. liberal fluid strategies—to uncover what the latest research says. We examine the complexities of blood pressure management during surgery, highlighting how individualized care is reshaping our approach to hemodynamic targets. We also debunk common myths surrounding AKI management and prevention. Looking ahead, we explore potential advancements in AKI care, including personalized medicine, the role of biomarkers in risk assessment, and the importance of understanding AKI trajectories.
