Dynamics of ionized magnesium and ionized calcium during recovery from diabetic ketoacidosis managed with conventional treatment.

Serial measurements of ionized magnesium (iMg), ionized calcium (iCa) and pH performed during the management of diabetic ketoacidosis (DKA) in a 10 9/12-year-old female showed a progressive decrease in iMg and iCa to subnormal values which inversely correlated with the increase of pH, suggesting a state of depletion of these cations during conventional DKA management.
