Abstract

Changes in ionized calcium (iCa) concentration seem to occur in newborns when the calcium supply from the mother is disconnected at birth, and a related hypocalcemia is produced. Thus, measurement of iCa is of particular importance in newborns. The aim of this study was to compare two methods of iCa measurement. We collected 50 samples from newborns in which we obtained values of iCa using both the direct and the indirect measurement. There is a significant correlation between iCa values obtained from Omni C and those obtained from the calculated method
