Blood Transfusion and Apheresis: Impact on Ionized Magnesium and Ionized Calcium
Blood Transfusion and Apheresis:
Impact on Ionized Magnesium and Ionized Calcium
Blood transfusion and apheresis protocols can be life-saving for critically ill patients by removing toxins, medications, destructive antibodies, or clotting factors from peripheral blood. However, blood levels of ionized magnesium (iMg) may drop as much as 60% at the end of an apheresis procedure. In addition, citrate used as an anticoagulant will bind with calcium, inducing hypocalcemia in many cases. In the current presentation, Dr. Sanford will discuss concerns around apheresis and transfusion procedures including the symptoms observed when magnesium or calcium are depleted and the effects of supplementation. She will also review the factors in different patient populations that influence the type of replacement fluid chosen, the necessity to monitor both iMg and iCa in these patients, and the importance of supplementing according to their ionized levels.

The importance of measuring ionized magnesium
in critically ill patients
Hypomagnesemia (low levels of magnesium) is associated with several clinical conditions, ranging from cardiovascular disease to transplantation and sepsis. Traditionally, total magnesium (tMg) measured in the laboratory is used to identify patients with hypomagnesemia. However, various studies have shown the clinical significance of using iMg, the biologically active form of magnesium, to correctly identify patients with hypomagnesemia. Dr. Naveen Bangia will review the clinical literature around the utility of measuring iMg in various clinical settings.
