About this study

Official title: Comparison of Activated Coagulation Time Between Hemochron Jr and ACT Plus During Cardiac Surgery for Patient Using Acute Normovolemic Hemodilution

This study aimed to compare 2 activated clotting time analysers (Hemochron Jr vs. ACT Plus).

Read the detailed description

Measurement of activated clotting time (ACT) is a standard method for anticoagulation monitoring. Especially in cardiac surgery, heparin is usually used as anticoagulant and protamine is used to reverse anticoagulation effect at the end of surgery. ACT method defines the time until a clot is formed in a test tube after triggering of internal pathway coagulation using blood activating agents (eg. kaolin).

Acute normovolemic hemodilution (ANH) consists of withdrawing patient's blood volume early in the operative period and concurrent infusion of crystalloid or colloid to maintain intravascular volume, and is used in cardiac surgery. ANH is known to affect hemostasis in some studies.

Assuming that accurate monitoring of coagulation therapy is important to prevent both thrombotic and hemorrhagic complications, we compared ACT results from 2 analysers (Hemochron Jr and ACT Plus) in patients undergoing cardiac surgery using ANH.

Questions about this trial

What is this clinical trial studying?

A study testing Hemochron and ACT Plus in people with Cardiac Disease, run by Hallym University Medical Center at 1 site in South Korea.

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 1 inclusion and 3 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 29 Jun 2015. 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 South Korea. 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. 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?

Comparison of activated coagulation time between Hemochron Jr and ACT Plus (time frame: During cardiac surgeris (within 8 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 NCT02484157, which also lists 4 linked publications.

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 29 Jun 2015.
