Three Anticoagulation Strategies for Hemodialysis in Patients at Risk of Hemorrhage: a Multicenter Randomized Trial

The aim of our study is to assess three anticoagulation strategies for intermittent hemodialysis(IHD) in patients at risk of hemorrhage. A registry of consecutive hemodialysis patients with high risk of hemorrhage was conducted at the Guangdong General Hospital, the First Affiliated Hospital of Guangzhou University of Chinese Medicine, the Second Affiliated Hospital of Guangzhou Medicine University or Guangzhou Hospital of Chinese Medicine, between Sep 10, 2017 and June 30th,2018. In this multi-center prospective and randomized study, participants were randomly divided into three groups during IHD according to different anticoagulation, including with regular saline flushes, one stage regional citrate anticoagulation (RCA) and two-stage RCA.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Briefly, there are two parts in this study. The first part of the study is to compare two-stage RCA with one stage RCA during IHD, and the second part is to compare two-stage RCA with regular saline flushes, with estimated total procedures, 78 and 48, respectively. The primary outcome was measured as therapy interruption based on visible serious circuit clotting or persistent alarms such as venous pressure (> 200 mmHg) or TMP(transmembrane pressures) (> 300 mmHg). The secondary outcomes included circuit survival time, the total clotting score of ECC(extracorporeal circuit ) and urea clearance (Kt/V and URR). The total clotting score was the sum of the clotting scores for the venous expansion chamber, arterial expansion chamber, and dialyzer.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
