Recalcitrant hypoglycemia resolved with 2.5% dextrose containing replacement fluid during hemodiafiltration

Abstract

A 52-year-old African American male was admitted with acute kidney injury (AKI) four days after renal cryotherapy. He was started on continuous veno-venous hemodiafiltration (CVVHDF) immediately but his subsequent course was complicated by recurrent hypoglycemia, poorly responding to conventional therapy. To address the recalcitrant hypoglycemia, we changed the replacement fluid to 5% dextrose in water with 150?mEq/L of sodium bicarbonate, Y-connected with 0.9% sodium chloride at a global rate of 2000?mL/hr, with resolution of refractory hypoglycemia. A modified CVVHDF employing hyperglycemic solution can be a valuable addition in treatment of AKI complicated by severe refractory hypoglycemia.
