About this study
This is a prospective, randomized, single blinded, controlled clinical trial designed to compare the clinical effects of sedation with dexmedetomidine versus propofol in patients undergoing cardiac surgery.
Read the detailed description
The study will include adult patients of both sexes scheduled for elective cardiac surgery with the use of cardiopulmonary bypass (including coronary artery bypass grafting, valve repair/replacement, and combined).
The patients included in the study will be randomized in 1:1 ratio using computer generated numbers into two groups. The first group of patients, upon arrival to the intensive care unit will be sedated with continuous dexmedetomidine infusion in doses 0.2-0.7 mcg/kg/h. Dexmedetomidine infusion will be discontinued before weaning from mechanical ventilation and extubation. The second group of patients, upon arrival to the intensive care unit will be sedated with continuous propofol infusion in doses 1-2 mg/kg/h. Propofol infusion will also be discontinued before weaning from mechanical ventilation and extubation.
Sedation level will be assessed using Richmond Agitation and Sedation Scale (RASS) every two hours. Postoperative analgesia will be managed according to protocol (opioid analgesics, non-steroid anti-inflammatory drugs, paracetamol), with pain level assessment using visual analog scale (0 - no pain; 10 - unbearable pain).
The following data will be registered: age, sex, body mass index (BMI), hemoglobin, heart rate, and LVEF. Among the postoperative parameters, the following will registered: duration of mechanical ventilation (in hours), extubation time, ICU and hospital length of stay (in days), postoperative hemoglobin, blood product transfusion rates, occurrence of atrial fibrillation and assessment of delirium. Assessment of delirium will be performed using the confusion assessment method for intensive care unit (CAM-ICU) every 12 hours during five postoperative days.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a prospective, randomized, single blinded, controlled clinical trial designed to compare the clinical effects of sedation with dexmedetomidine versus propofol in patients undergoing cardiac surgery.
Detailed description
The study will include adult patients of both sexes scheduled for elective cardiac surgery with the use of cardiopulmonary bypass (including coronary artery bypass grafting, valve repair/replacement, and combined).

The first group of patients, upon arrival to the intensive care unit will be sedated with continuous dexmedetomidine infusion in doses 0.2-0.7 mcg/kg/h.

The second group of patients, upon arrival to the intensive care unit will be sedated with continuous propofol infusion in doses 1-2 mg/kg/h. Propofol infusion will also be discontinued before weaning from mechanical ventilation and extubation.

Postoperative analgesia will be managed according to protocol (opioid analgesics, non-steroid anti-inflammatory drugs, paracetamol), with pain level assessment using visual analog scale (0 - no pain; 10 - unbearable pain).
The following data will be registered: age, sex, body mass index (BMI), hemoglobin, heart rate, and LVEF. Among the postoperative parameters, the following will registered: duration of mechanical ventilation (in hours), extubation time, ICU and hospital length of stay (in days), postoperative hemoglobin, blood product transfusion rates, occurrence of atrial fibrillation and assessment of delirium. Assessment of delirium will be performed using the confusion assessment method for intensive care unit (CAM-ICU) every 12 hours during five postoperative days.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Dexmedetomidine and Propofol in people with Intensive Care Unit Delirium, run by University of Novi Sad at 1 site in Serbia.
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 2 inclusion and 8 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: looking for participants now, as of the sponsor's last update on 4 Dec 2024. 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 Serbia. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mihaela Preveden, MD (+381214805702, mihaela.detki@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Occurrence of postoperative delirium (time frame: 5 days). 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 4 Dec 2024; AzTrials last refreshed its copy on 8 Nov 2026.
