NCT05070182

Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • REE changes

    Changes in REE in patients with brain damage

    Day 0 (upon entry to ICU) up to 30 days

  • MCA changes

    Changes in flow rates in Median Cerebral Artery (MCA) in patients with brain damage

    Day 0 (upon entry to ICU) up to 30 days

  • REE and MCA correlation

    Correlate the REE changes with those in flow rates in MCA

    Day 0 (upon entry to ICU) up to 30 days

Secondary Outcomes (1)

  • Prognostic value of REE

    Day 0 (upon entry to ICU) up to 30 days

Study Arms (1)

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

Diagnostic Test: REE - Resting Energy ExpenditureDiagnostic Test: Transcranial Doppler

Interventions

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.

Patients with brain damage
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.

Patients with brain damage
