Beschrijving
Inclusion Criteria:
A. Aged 18 to 80 years, inclusive, male or female; B. Diagnosed with acute kidney injury or chronic kidney disease stage 5, and assessed by a physician as requiring continuous renal replacement therapy (CRRT); C. Citrate metabolism disorder, including liver failure (acute liver failure, acute-on-chronic liver failure, or decompensated cirrhosis), and/or microcirculation disorder (mean arterial pressure <65 mmHg requiring vasopressor therapy and lactate ≥2 mmol/L); D. The investigator determines that the patient can have a stable vascular access established (the access must be capable of providing a constant and effective blood flow rate >150 ml/min); E. The study participant (subject) and their legal guardian are able to understand the study purpose and provide written informed consent.
Exclusion Criteria:
A. Received regional citrate anticoagulation therapy within the previous 72 hours; B. Expected to require additional non-protocol calcium supplementation during CRRT due to disease-related needs; C. Requiring arterial-venous reversal of the extracorporeal circuit during CRRT due to poor flow; D. Requiring concurrent peritoneal dialysis during the trial period; E. Participated in or is currently participating in another clinical trial within 1 month prior to the date of signing the informed consent form; F. Expected survival time less than 72 hours; G. Any other conditions that, in the investigator's judgment, make the patient unsuitable for participation in the clinical trial.

Experimenteel: Two-stage
|
The two-stage calcium supplementation refers to: the first stage after the initiation of CRRT, the amount of calcium supplementation includes the calcium clearance from the extracorporeal circuit and the accumulated calcium citrate in the body; when the blood citrate concentration reaches a steady state, the second stage begins, at which point the accumulated calcium is stable and only the calcium clearance from the extracorporeal circuit needs to be supplemented.

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Intervention rate of iCa
Tijdsspanne: From 1 hour post-CRRT initiation to the end of CRRT
|
During the CRRT iCa is measured at pre-set time points.
If the iCa concentration is either <0.95 or >1.35 mmol/L in the body, or <0.25 or >0.4 mmol/L in the extracorporeal circuit, it is defined as "iCa requiring intervention".
If both intracorporeal and extracorporeal iCa require intervention at the same time point, it is counted as two interventions.
Finally, the intervention rate of iCa is calculated.
