Accuracy of methods to estimate ionized and “corrected” serum calcium concentrations in critically ill multiple trauma patients receiving specialized nutrition support

Abstract: Aberrations in calcium homeostasis are frequent (27%) in postresuscitative critically ill multiple trauma patients. Methods for predicting hypocalcemia lack sensitivity and are often associated with an unacceptable rate of false negatives. Predictive methods for estimating ionized or corrected serum concentrations should not be used. Direct measurement of serum iCa concentration is indicated for assessing calcium status for this population.

“…Approximately 40% is bound to serum proteins, principally albumin, and the remainder is bound to anions such as phosphate. Because the binding of calcium to proteins is affected by pH, ionized calcium in blood is commonly corrected to a standard pH (12). The ionized calcium was pH adjusted.…”
