Trial summary

The objective of the study is to compare the effects of 48 hours ketamine infusion versus sufentanil infusion on brain glutamate concentrations measured with microdialysis after traumatic brain injury. We hypothesize that ketamine infusion will decrease high glutamate values faster than sufentanil. Read more about this study

About this study

Official title: Effect of Ketamine Versus Sufentanil on Cerebral Glutamate After Traumatic Brain Injury : a Randomized, Double-blinded, Microdialysis Study

The objective of the study is to compare the effects of 48 hours ketamine infusion versus sufentanil infusion on brain glutamate concentrations measured with microdialysis after traumatic brain injury.

We hypothesize that ketamine infusion will decrease high glutamate values faster than sufentanil.

Read the detailed description

Inclusion of 20 consecutive head trauma patients. Randomization and double-blind to compare the effects of ketamine versus sufentanil on brain glutamate concentrations measured with microdialysis.

Ketamine is an anti-N-methyl-D-aspartate (NMDA) medication. It is supposed to limit excitotoxicity of amino-acids, especially glutamate. Glutamate is known to be elevated in more than 60% of the severe head trauma patients. It induces cortical spreading depression which can aggravate prognosis. It's a daily used medication in anesthesia and intensive care units for sedation and induction of anesthesia. It's the recommended medication for induction of unstable wounded soldiers on the field because of its neutrality on haemodynamic state.

Sufentanil is the reference opioid for sedation in ICU in Europe. It can induce hypotension which is deleterious for cerebral perfusion pressure after brain trauma.

In our unit, patients with severe head injury are monitored by a triple lumen access device including ICP (IntraCerebral Pressure), PtiO2 (oxygen pressure in the brain) and microdialysis. This last monitoring allows measurement of brain parenchymal concentrations of small molecules : glucose, lactate, pyruvate, glutamate, glycerol,.... It's a tool to evaluate the metabolic state of the brain divided into 4 categories : normal, hyperglycolysis, ischemia and metabolic crisis.

Then, we will detail the effects of ketamine on metabolic state of the brain, especially glutamate concentration. Normal values are below 10 micromol/ml. After head trauma it can dramatically increase to values up to 50 or even 100 micromol/ml, with normalization after 24 hours. Ketamine is expected to decrease these high values faster than described in observational studies.

What is being measured

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

  1. brain glutamate concentrations

    To compare the kinetic of brain glutamate concentration decrease during 4 periods of 12 hours between ketamine infusion group (KET) and sufentanil standard infusion group (STD)

    Measured: H0-H12, H12-H24, H24-H36 and H36-H48

Secondary outcomes (4)
  1. metabolic profile

    To compare the brain metabolic profile (normal, ischemic, hyperglycolytic and metabolic crisis) of the patients related to their group of treatment : ketamine (KET) and sufentanil (STD) by measuring brain glucose, brain lactate, brain glycerol concentrations and brain lactate/pyruvate ratio.

    Measured: H0-H12, H12-H24, H24-H36 and H36-H48

  2. Episodes of intracranial hypertension (ICHT) and brain ischemia

    To compare the number of ICHT episodes (ICP>20 mm Hg more than 15 minutes) and to compare the number of ischemic episodes (PtiO2<20 mm Hg more than 15 minutes) between the 2 groups

    Measured: H0-H12, H12-H24, H24-H36 and H36-H48

  3. Therapeutic Intensity Level (TIL)

    To compare the TIL value between the 2 groups. TIL is a score developed to measure the intensity of cares for head trauma patients. Lower scores are meaning less intense cares. It is calculated for 24 hours periods.

    Measured: Days 1 and 2

  4. Glasgow Outcome Scale (GOS) et extended Glasgow Outcome Scale (eGOS)

    To describe the prognosis of the patients of the KETAMINE group versus SUFENTANIL group. GOS is the international validated score for evaluation of the prognosis after head trauma.

    Measured: 6 months and 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ketamine and Sufentanil in people with Head Trauma, run by Pierre-Julien CUNGI at 1 site 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 3 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 5 Sep 2014. 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 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Ambroise MONTCRIOL, MD (0483162358 ext. 0033, ambroise.montcriol@free.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

brain glutamate concentrations (time frame: H0-H12, H12-H24, H24-H36 and H36-H48). 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 NCT02232347, which also lists 13 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 5 Sep 2014.
