Although postoperative acute kidney injury (AKI) is a serious complication after cardiac surgery, preventive measures are limited. Despite the known association of preoperative low magnesium levels with cardiac surgery–related atrial fibrillation, the association between preoperative magnesium concentration and postoperative AKI has not been fully elucidated.

In this webinar, Dr. Hee Byung Koh, Department of Internal Medicine, College of Medicine, Institute of Kidney Disease Research, Yonsei University, Seoul, South Korea. will describe the association between preoperative serum ionized magnesium level and the development of AKI after cardiac surgery. He will discuss the need for close monitoring of ionized magnesium levels, both preoperatively and intraoperatively, and the benefits of active magnesium supplementation.
