Trial summary

Context: A major lack of organ donors is a serious public health problem. It determines a prolonged delay before a transplant can be performed and thus a significant number of deaths of patients waiting for transplantation. Read more about this study

About this study

Official title: Interest of Real Time Measurement of Autonomous Nervous System for the Detection of Brain Death: the MEANS Study

Context: A major lack of organ donors is a serious public health problem. It determines a prolonged delay before a transplant can be performed and thus a significant number of deaths of patients waiting for transplantation. The aim of this project is to reduce the delay of the diagnosis of brain death, and also to improve its diagnosis in the Intensive Care Unit.

The diagnosis of brain death is strictly defined by the law and relies either on two consecutive flat electroencephalograms recorded at an interval of four hours, or on the lack of cerebral circulation during a brain angiography performed after suspecting brain death on the clinical exam. However, in usual practice, it is difficult to have all the needed clinical arguments, and their interpretation can be difficult in the pathological context. This may participate in the delay and the lack of patients potentially donors.

Pre-study: In a pilot study, fifty subjects with severe cerebral lesions, had a continuous ECG recording. The investigators could find that a decrease in autonomic nervous system activity, as measured through the ECG, was correlated to the transition to brain death assessed by cerebral angiography. The loss of cardiac variability was always observed between two cerebral angiographies, one before and the second after brain death. This study allowed the investigators to calculate the threshold values of sympathetic and parasympathetic activities to confirm brain death.

Read the detailed description

Aim: The aim of this second study is to validate prospectively the interest of the analysis in real-time of autonomic nervous system activity to detect brain death.

Benefits expected: Increase the number of organ donors and the number of organs removal available for transplantation.

What participants receive

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

Study groups in NCT00918970
Study groupRoleWhat they receive
SNA groupThis group will have a real-time analysis of autonomic nervous system activity during its intensive care hospitalisation
Clinical groupThis group will have a conventional clinical analysis during its intensive care hospitalisation

What is being measured

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

  1. the delay between the falling down of autonomic nervous system activity and the confirmation of the brain death using cerebral angiography

    Measured: At confirmation of the brain death

Secondary outcomes (1)
  1. the number of patients and the number of organs removed

    Measured: At the end of the study

Questions about this trial

What is this clinical trial studying?

An observational study of Cerebral Hematoma, Traumatic and Intracerebral Hemorrhage, Traumatic, run by Centre Hospitalier Universitaire de Saint Etienne at 3 sites in France.

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 2 inclusion and 6 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: stopped early, as of the sponsor's last update on 15 Jun 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in France. 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 was stopped early (reason given: Angioscanners in excess of the SNA group because of use of thiopental). Results are not available in the source record.

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?

the delay between the falling down of autonomic nervous system activity and the confirmation of the brain death using cerebral angiography (time frame: At confirmation of the brain death). 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 15 Jun 2009.
