About this study
Official title: Resting Energy Needs in Brain Dead Patients
The study will examine the resting energy need (REE) in patients suffering from brain damage. For the measurement of REE will be used a metabolic computer (which with continuous recording of breath-to-breath volume (Vt), respiratory rate (RR) of ventilation per minute volume (MV) ), of inhaled and exhaled gases (O2 and CO2) has the ability to calculate the values of VO2, VCO2 and with the help of equations the values of REE and RQ.
Read the detailed description
This is a retrospective observational study concerning patients suffering from brain damage.
All the patients suffering from brain damage are monitored in order to examine their resting energy needs (REE). For the measurement of REE the metabolic computer (Medical Graphics, Ultima CCM, Minneapolis, USA) is used.
The main purpose of this study is to reveal the (REE) changing in patients with brain death semiology and examine if the REE changes could be related to the outcome of a patient with intracranial pathology. Moreover the study will examine if the changes in REE measurement are related to changes in flow velocities in the midbrain.
Any measurement shall be preceded by calibration of the metabolic computer pneumotachograph with a 3-liter syringe with an acceptable error of less than 9 ml / lit. The metabolic unit is calibrated for VO2 measurements with two calibration cylinders containing 21% and 12% O2 and for VCO2 measurements with calibration gases containing 5% and 0% CO2 respectively.
The measurement of flow velocities in the middle cerebral artery will be done with the transcranial Doppler using a low frequency (2 MHz) ultrasound head After their final diagnosis (brain death or not) the patients' characteristics will be compared according to the categorization as "brain dead" or not.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
REE - Resting Energy ExpenditureDiagnostic test
REEs represent 60-70% of the needs for a sedentary person and 50% of physically active people.
For the measurement of REE will be used the metabolic computer (Medical Graphics, Ultima CCM, Minneapolis, USA), which with continuous recording of breath-to-breath volume (Vt), respiratory rate (RR) of ventilation per minute volume (MV) ), of inhaled and exhaled gases (O2 and CO2) has the ability to calculate the values of VO2, VCO2 and with the help of equations the values of REE and RQ.
All patients in the study will be monitored with the metabolic computer. Their measurements will be recorded every day during their stay in the ICU.
Transcranial DopplerDiagnostic test
The measurement of flow velocities in the middle cerebral artery will be done with the transcranial Doppler using a low frequency (2 MHz) ultrasound head.
All patients entering the study will be examined with the TCD every day during their stay in the ICU.
| Study group | Role | What they receive |
|---|---|---|
| Patients with brain damage | ICU patients with brain damage (due to cardiac arrest, intracranial hemorrhage or traumatic brain injury). and GCS upon entry <=8.
All patients will be examined with a transcranial doppler (TCD) and a metabolic computer (for the measurements of REE) After the final diagnosis the patients' characteristics will be compared according to if they were brain dead or not Receives: Diagnostic Test: REE - Resting Energy Expenditure; Diagnostic Test: Transcranial Doppler |

Questions about this trial
What is this clinical trial studying?
An observational study of Brain Death and Brain Injuries, run by Aristotle University Of Thessaloniki at 1 site in Greece.
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 3 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 7 Oct 2021. 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 Greece. 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?
REE changes (time frame: Day 0 (upon entry to ICU) up to 30 days). 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?
On the ClinicalTrials.gov record for NCT05070182, which also lists 4 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 7 Oct 2021.
