ListOutcomeTime frameDescription
PrimaryChanges in systemic total magnesium concentrationBefore CRRT initiation (baseline) and at 2, 6, 12, 18, 24, 48, and 72 hours after initiation.
Changes in systemic total magnesium concentration (mmol/L), measured using conventional clinical laboratory methods, will be assessed from baseline and over time during continuous renal replacement therapy with regional citrate anticoagulation.
PrimaryChanges in systemic ionized magnesium concentrationBefore CRRT initiation (baseline) and at 2, 6, 12, 18, 24, 48, and 72 hours after initiation.
Changes in systemic ionized magnesium concentration (mmol/L), measured using ion-selective electrode technology, will be assessed from baseline and over time during continuous renal replacement therapy with regional citrate anticoagulation.
PrimaryCitrate-associated changes in magnesium ionizationAt 2, 6, 12, 18, 24, 48, and 72 hours after CRRT initiation.
Changes in the ionized magnesium fraction (ionized magnesium/total magnesium) between systemic and pre-filter blood will be assessed following administration of citrate-containing predilution fluid, accounting for dilution. Ionized magnesium will be measured using ion-selective electrode technology and total magnesium using conventional clinical laboratory methods.
PrimaryMagnesium flux across the extracorporeal filterAt 2, 6, 12, 18, 24, 48, and 72 hours after CRRT initiation.
Magnesium flux across the extracorporeal filter (mmol/h) will be calculated using total and ionized magnesium concentrations in pre-filter and post-filter blood and effluent fluid, accounting for blood flow rates, treatment fluid flow rates and fluid composition. Ionized magnesium will be measured using ion-selective electrode technology and total magnesium using conventional clinical laboratory methods.
PrimaryNet magnesium loss attributable to CRRTAt 2, 6, 12, 18, 24, 48, and 72 hours after CRRT initiation.
Net magnesium loss attributable to CRRT (mmol/h) will be calculated from magnesium removal in the effluent, accounting for magnesium supplied through dialysate and post-filter replacement fluids. Calculations will use the actual treatment fluid composition and flow rates at each sampling time. Ionized magnesium will be measured using ion-selective electrode technology and total magnesium using conventional clinical laboratory methods.
SecondaryChanges in systemic total calcium concentrationBefore CRRT initiation (baseline) and at 2, 6, 12, 18, 24, 48, and 72 hours after initiation.
