About this study
Official title: Assessment of the echOpen Ultra-portable Ultrasound Device in Daily Use by Clinicians. Part I: Identification of Effusion and Detection of Basilic Vein
In recent years, portable and ultra-portable ultrasound devices are increasingly used by the non radiologists, notably cardiologists or obstetrician gynecologist, at the patient's bedside to visualize and measure anatomical structures and fluid and provide the clinical examination with additional signs allowing quicker and more confident clinical decisions.
This innovative approach is slowed down by the accessibility of these miniaturized devices, the price of which remains high.

The echOpen device includes an ultra-portable ultrasound probe and a mobile application that allows the image to be displayed on a smartphone via a WIFI protocol.
The objective of the clinical investigation is to show that the echOpen device, using three frequencies 3.5 Mhz, 5.0 Mhz and 7.5 Mhz, allows identifying the semiological signs or anatomical structures of interest located at several depths of the body, with a performance similar to other devices routinely used in clinical departments.
Read the detailed description
The echOpen device includes an ultrasound probe and a mobile application. The mechanical probe emits at three ultrasound frequencies, 3.5 Mhz, 5.0 Mhz and 7.5 Mhz, which allows the exploration of the interior of the body at different depths in a non-invasive and non-irradiating manner.
Thus, the purpose of the echOpen device is, on one hand, to guide the diagnosis during the clinical examination and, on the other hand, to identify anatomical structures in order to assist in management.
The objective of the clinical investigation is to demonstrate that the echOpen device is able to identify semiological signs and localize anatomical structures at different depths of the body, with a performance not inferior to that of other ultrasound devices, routinely employed in hospital clinical departments.
The signs of interest (i.e. search for an intra-abdominal (3.5 Mhz) and pleural (5.0 Mhz) effusion) were chosen for their clinical usefulness (their presence during the clinical examination constitutes an argument for orientation and/or severity) and for their prevalence in the study population.
The identification of anatomical structure of interest (i.e. detection of basilic vein (7.5Mhz)) was chosen because it is a gesture frequently used when taking in charge of a patient hospitalized in the selected departments.
An ultrasound probe in use in the hospital clinical departments where the investigation takes place will be employed as a comparator to judge the performance of the echOpen device.
This clinical investigation is part of a CE marking procedure.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EchOpen ultra-portable ultrasound deviceDevice
Depending on the clinical picture, patients are examined to detect the presence or absence of pleural effusion, or intra-abdominal effusion, or to localize the basilic vein
Ultrasound device routinely used in the department.Device
Patients who were first examined with the EchOpen ultra-portable ultrasound device, are secondarily examined with an ultrasound probe used routinely in the department.
Standard ultrasound examination by an independent referent radiologistProcedure or surgery
In a case of discordance between the assessments made with echOpen and the usual ultrasound device, an independent referent radiologist will use a standard ultrasound machine to constitute the gold standard (GS) rating
| Study group | Role | What they receive |
|---|---|---|
| Patients benefitting ultrasound examination | Experimental | This is the only arm of the study. Patients with an indicative clinical picture that leads the clinician to resort to the use of an ultrasound to potentially support the diagnosis will be examined to verify the presence of pleural effusion or intra-abdominal effusion, or to identify basilic vein. The patients will be assessed first with the echOpen device and second witn an ultrasound routinely used in the department.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

A study testing EchOpen ultra-portable ultrasound device, Ultrasound device routinely used in the department. and Standard ultrasound examination by an independent referent radiologist in people with Pleural Effusion and Abdominal Effusion, run by Assistance Publique - Hôpitaux de Paris at 4 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 5 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: finished, as of the sponsor's last update on 8 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Presence of Pleural effusion (time frame: Day 0). The study lists 3 primary outcomes in all. 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 8 Dec 2022.
