It is well known that citrate induces ionized hypocalcaemia by the chelating effect during plateletpheresis. However, the kinetics of serum magnesium (Mg) ions has not been well documented. We, therefore, evaluated biochemical changes in healthy donors during plateletpheresis procedure. Ten healthy donors underwent plateletpheresis on continuous cell separator (CS3000, Baxter, Round Lake, IL, USA) and 10 on intermittent flow cell separator (MCS 3p, Hemonetics, Braintree, MA, USA). Serum levels of total and ionized calcium (tCa and iCa, respectively) and Mg (tMg and iMg, respectively) were measured before, during and after the procedures. Although, the fall in tCa (from 2·62 ± 0·12 to 2·36 ± 0·12 mmol L −1 ) and tMg (from 0·89 ± 0·01 to 0·79 ± 0·01 mmol L −1 ) was modest and not significant; drop in iCa (from 1·33 ± 0·1 to 0·84 ± 0·1 mmol L −1 ) and iMg (from 0·53 ± 0·01 to 0·35 ± 0·1 mmol L −1 ) was statistically significant (P < 0·001). There were no significant differences observed between the CS3000 and MCS 3p cell separators regarding the fall in Ca and Mg. None of the donors experienced any adverse reactions during the procedures. In the study, an acute ionized hypocalcaemia and hypomagnesaemia have been observed after the plateletpheresis; therefore, measurement of both the ions may be monitored. However, there is no justification for prophylactic supplementation of either of these elements. [ABSTRACT FROM AUTHOR]
