About this study
The use of protective ventilation (to maintain normoxia and normocapnia), optimise haemodynamics, diagnose/treat seizures, therapeutic hypotermia etc is recommended for ICU management of patients who have had cardiac arrest and remain in coma after return of spontaneous circulation according to the latest International Guidelines. These actions essentially aim to limit secondary brain injury but despite all therapeutic effort, the cerebral oxygenation may remain inadequate and there is no validated method to avoid such a state in real time.

The use of protective ventilation (to maintain normoxia and normocapnia), optimize hemodynamics, diagnose/treat seizures, therapeutic hypothermia etc is recommended for ICU management of patients who have had cardiac arrest and remain in a coma after the return of spontaneous circulation according to the latest International Guidelines. These actions essentially aim to limit secondary brain injury but despite all therapeutic effort, the cerebral oxygenation may remain inadequate and there is no validated method to avoid such a state in real time.
The objective of this study is to assess the relationship between jugular venous oximetry and neurological outcome of comatose patients after cardiac arrest, evaluated as per the Cerebral Performance Category scale (CPC). Further, the aim is to clarify relations between biomarkers protein S100B, neuron-specific enolase (NSE) and parameters of jugular oximetry for prognostication. An anticipated total of sixty patients will be enrolled in this non-randomised, single-group, double-blind study.
In the course of the study, the authors have decided to stop using BIS monitoring for sedation management. Reason for this decision was very limited reliability of this technique in unparalyzed patients on ICU (muscle artifacts). New aim of sedation was Richmond Agitation Sedation Scale (RASS) -4 or -5, with avoiding shivering and clinically manifested seizures.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
BIS Monitor-guided sedationOther

Measured: 24 months
Serum S100B level
The serum S100B level will be monitored after admission of the patients to ICU
Measured: 24 months
Serum NSE level
The serum NSE level will be monitored after admission of the patient to ICU and 24, 48 and 72 hour after cardiac arrest
Measured: 24 months

Secondary outcomes (1)
Functional status
Functional status defined with using cerebral performance category (CPC) classification will be assessed at time of discharge from the hospital and at 3 months after cardiac arrest
Measured: 24 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The use of protective ventilation (to maintain normoxia and normocapnia), optimise haemodynamics, diagnose/treat seizures, therapeutic hypotermia etc is recommended for ICU management of patients who have had cardiac arrest and remain in coma after return of spontaneous circulation according to the latest International Guidelines. These actions essentially aim to limit secondary brain injury but despite all therapeutic effort, the cerebral oxygenation may remain inadequate and there is no validated method to avoid such a state in real time.

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?

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 29 Mar 2019; AzTrials last refreshed its copy on 8 Nov 2026.
