Read the detailed description

Delirium is an acute brain disorder that involves changes in consciousness, attention, cognition, and perception.The incidence of postoperative delirium (POD) is high among patients undergoing cardiac surgery, ranging from 20 to 50%, and the risk is even higher in the elderly.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PregabalinDrug

    Patients will receive pregabalin capsules (75 mg) every 12 h for 24 hours by nasogastric tube.

  • DexmedetomidineDrug

    Patients will receive a bolus dose of 0.4 μg/kg dexmedetomidine (over a period of 10 to 20 min)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent of delirium treatment

    Measured: 24 hour postoperatively

Secondary outcomes (3)
  1. Level of sedation

    Sedation level will be assessed by using the Ramsey sedation scale.

    Measured: 24 hour postoperatively

  2. Incidence of weaning from mechanical ventilation

    percent of patients who weaned from mechanical ventilation

    Measured: 1 week postoperatively

  3. Length of hospital stay

    Measured: 1 month postoperatively

A Phase 4 study testing Pregabalin and Dexmedetomidine in people with Pregabalin and Delirium Treatment, run by Tanta University at 1 site in Egypt.

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 1 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: looking for participants now, as of the sponsor's last update on 25 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 Islam Morsy, MD (00201093387374, eslam.morsy@med.tanta.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent of delirium treatment (time frame: 24 hour postoperatively). 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?
