Today, Dr. Monica Gray, Dr. Pradip Kamat, and Dr. Rahul Damania discuss two real-life pediatric cases of hyponatremia in the PICU. They talk through a case of a six-month-old baby with severe sodium depletion and a teenager dealing with cancer-related hyponatremia. The team breaks down the pathophysiology, walks us through the diagnostic workups, and discusses the careful management needed for these cases. They emphasize the importance of correcting sodium levels gradually and addressing the root cause of the problem. They share practical tips for intensivists and highlight why staying vigilant and following evidence-based care is so crucial when managing critically ill kids with electrolyte disturbances. Tune in to hear more!

Show Highlights:
