About this study

Official title: A Prospective, Randomized Clinical Trial Comparing Blood Product Use and Bleeding Events During and After Endoscopic or Neurosurgical Procedures in Patients With Cirrhosis and Coagulopathy: Rotational Thromboelastography (ROTEM) Versus Conventional Therapy

A prospective, randomized clinical trial comparing blood product use and bleeding events during and after endoscopic or neurosurgical procedures in patients with cirrhosis and coagulopathy: Rotational Thromboelastometry (ROTEM) vs. conventional therapy (SCARLET).

Read the detailed description

Orthotopic liver transplantation (OLT) can be associated with significant bleeding requiring multiple blood product transfusions, especially in patients with severe liver dysfunction. Rotational thromboelastometry (ROTEM) is a point-of-care device that has been used successfully to monitor coagulation on whole blood samples during OLT. Whether it allows blood loss and transfusion to be reduced during OLT remains controversial. ROTEM or conventional coagulation tests were used in this study to guide transfusion of platelets, cryoprecipitate, and fresh frozen plasma (FFP) during OLT. Patient characteristics as well as pre- and post- transplant laboratory data were collected. Intra-operative blood loss, type and amount of blood products transfused, and cost were compared between the two groups.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ROTEMDevice

    Assess coagulopathy with ROTEM device compared to conventional laboratory tests. ROTEM will be used on all patients, however, determination of blood products used will be based on patient's randomization group.

  • Conventional TherapyOther

    Assess coagulopathy with conventional laboratory tests (PT/INR, Hemoglobin, Platelet count). Conventional laboratory tests will be obtained on all subjects, however, determination of blood products used will be based on patient's randomization group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Intra-operative Blood Loss

    Total amount of pre-procedure blood products transfused in patients undergoing endoscopy and neurosurgical procedures.

    Measured: Patients will be evaluated for the duration of their transfusion (no greater than 24 hour span).

Secondary outcomes (1)
  1. Number of Participants With Bleeding Events

    Duration of hospitalization is patient dependent, and is not affected by study interventions. Bleeding events (such as post-procedure bleeding, signs/symptoms of bleeding, or active hemorrhage) will be evaluated by chart review for the duration of each subject's hospitalization (up to a maximum of 6 months).

    Measured: Patients will be assessed for bleeding events from time of consent in the hospital to the time of discharge from the hospitalization (up to a maximum of 6 months).

Questions about this trial

What is this clinical trial studying?

A study testing ROTEM and Conventional Therapy in people with Cirrhosis and Coagulopathy, run by Ohio State University.

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 4 inclusion and 4 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 22 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 22 Jan 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Intra-operative Blood Loss (time frame: Patients will be evaluated for the duration of their transfusion (no greater than 24 hour span).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Jan 2021.
