Extracorporeal Membrane Oxygenation Evaluated by Transcranial Doppler. (ECMO-DTC)

April 16, 2018 updated by: University Hospital, Toulouse

Extracorporeal Membrane Oxygenation and Cerebral Blood Flow Velocity Evaluated by Transcranial Doppler

To determine how venoarterial extracorporeal membrane oxygenation (ECMO) affects cerebral blood flow velocity (CBFV) measured by transcranial doppler (TCD), to determine whether specific changes in cerebral blood flow velocity may be associated with neurologic injury and to determine modifications of CBFV after withdrawal of ECMO.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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

Venoarterial Extracorporeal membrane oxygenation (ECMO) is used in adult with refractory cardiac failure as a life-saving measure. Adults treated with ECMO survived to hospital discharge in 21,8% to 65,4% of cases. Neurologic complications such as intracranial hemorrhage, anoxia and ischemia are major causes of death and long-term disability in ECMO patients (7% to 14%). Current neurological monitoring techniques are insufficient to predict which critically ill patient receiving ECMO therapy will suffer from neurologic injury. Even after a clinical suspicion of neurologic injury, diagnosis can be difficult. TCD is commonly used to monitor the CBFV of traumatic brain injury. There are no reports that evaluate CBFV of patients requiring ECMO therapy. Patient will have to do both echocardiography and TCD to evaluate cardiac output and CBFV. We will repeat these dopplers every 24 hours until ECMO withdrawal and one day after explantation.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
30

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • adult patient who receiving ECMO therapy

Exclusion Criteria:

  • cervico-encephalic vasculopathy
  • lacked an acoustic window allowing for adequate TCD examination
  • stroke in medical past.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Patient treated with ECMO
Patient treated with ECMO will have Examination : a TCD and Trans-Thoracic Echocardiography (TTE)
Other: Examination : a TCD and Trans-Thoracic Echocardiography

Examination that involves the completion of a TCD and an TTE (Trans-Thoracic Echocardiography) :

  • To reports clinical parameters at the time of the examination : ECG data: sinus rhythm, atrial or ventricular arrhythmia, state of consciousness, heart rate, O2 saturation
  • To review of pharmacological parameters at the time of the examination : presence of sedation; presence, type and dose of catecholamines.
  • To collect biological data from the day of the examination : Partial Pressure of O2, PaCO2 (partial pressure) and hematocrit
  • To collect possible additional examinations : brain scan, EEG. These are non-invasive exams that do not require patient displacement. Only the samples taken by the medical team as part of the treatment will be analyzed.
Other Names:
  • Examination that involves a TCD and an TTE

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cerebral blood flow velocities evolution
Time Frame: 24 hours
Cerebral blood flow velocities evolution over the time
24 hours
The correlation of Cerebral blood flow velocities with the variation of the cardiac output and ECMO flow.
Time Frame: 24 hours
The correlation with the variation of the cardiac output and ECMO flow.
24 hours

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.
Outcome Measure
Measure Description
Time Frame
Relation between acute neurologic injury and variation of CBFV
Time Frame: 24 hours
Relation between acute neurologic injury and variation of CBFV detected by TCD.
24 hours
Modification of the CBFV detected by TCD after the withdrawal of the ECMO.
Time Frame: 24 hours
