Key result
Monitoring of the Q-oTc interval during plateletpheresis correlated significantly with free calcium levels (r = 0.592, p < 0.001) but could not substitute for direct measurement.

Direct calcium measurement remains necessary during plateletpheresis; this observational correlation leaves open whether refined ECG metrics could substitute.

Does ECG monitoring predict free calcium levels during reinfusion of citrate anticoagulated blood in subjects undergoing plateletpheresis?
Effect estimate: r = 0.592
p-value: p=< .001
Monitoring of the ECG cannot substitute for direct measurement of free calcium in citrate-induced hypocalcemia during plateletpheresis.
Ladenson et al. (1978) conducted an observational in Citrate-induced hypocalcemia during plateletpheresis (n=12). Reinfusion of citrate anticoagulated blood was evaluated on Correlation between free calcium (Ca F) and Q-oTc interval (r = 0.592, p=< .001). Monitoring of the Q-oTc interval during plateletpheresis correlated significantly with free calcium levels (r = 0.592, p < 0.001) but could not substitute for direct measurement.
