About this study

Do no monitor of post-circuit ionized calcium affact the filter life time of continueous renal replacement therapy with regional citrate anticoagulation circuit? A randomized control trial

Read the detailed description

Regional citrate anticoagulation is the gold standard of anticoagulation in patient receiving CRRT. In RCA circuit, there was a monitoring of pre-filter (systemic) ionized calcium and post-filter (circuit) ionized calcium. Pre-filter ionized calcium was monitored for observe the adverse effect of citrate such as hypocalcemia, citrate intoxication. However, post-filter ionized calcium was monitored for adjustment the citrate dose. We find many problem with frequently monitoring of post-ionized calcium such as confusion from markedly abnormal result, how to adjustment the citrate dose ,and increase workload for nurses. We hypothesis that if we can monitoring of post-filter ionized calcium?

Study groupRoleWhat they receive
No monitoring of post filter ionized calciumExperimentalStarting dialysis with continuous renal replacement therapy with regional citrate anticoagulation. Patients will receive standard treatments such as anti-bacterial agents, mechanical ventilator, vasopressors as appropriate. Citrate dose start at 4 mmol/L and no adjustment of citrate dose. Post-filter ionized calcium result will blind for physician. Other laboratory such as pre-filter ionized calcium, electrolyte, ABG, calcium, the ratio of total calcium to systemic ionized calcium will monitor every 8 hour.

Monitoring of post filter ionized calciumPlacebo comparatorStarting dialysis with continuous renal replacement therapy with regional citrate anticoagulation. Patients will receive standard treatments such as anti-bacterial agents, mechanical ventilator, vasopressors as appropriate. Citrate dose start at 4 mmol/L with adjustment of citrate dose to acheive post-filter ionized calcium at 0.25-0.35 mmol/L. Other laboratory such as pre-filter ionized calcium, electrolyte, ABG, calcium, the ratio of total calcium to systemic ionized calcium will monitor every 8 hour.

Questions about this trial

What is this clinical trial studying?

A study testing Regional citrate anticoagulation, Vasopressor and Antibiotic in people with Regional Citrate Anticoagulation and Ionized Calcium, run by Chulalongkorn University at 1 site in Thailand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Filter lifetime in hours (time frame: 72 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04792424, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2022.
