Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44334   clinical trials with a EudraCT protocol, of which   7366   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    In this study we primarily aimed at evaluating the influence of magnesium sulphate injection on the brain concentrations of propofol required to achieve a State Entropy value between 50-60, which corresponds to the recommended depth of anesthesia.
    The primary endpoint will be the target concentration of Propofol TCI to achieve a state entropy value between 50-60.
    E.2.2Secondary objectives of the trial
    Secondary end points were PPI by pupillometry with "AlgiScan®" monitoring, before endotracheal intubation and with a State Entropy of 50-60, then every 5 min between endotracheal intubation and surgical incision; the PRD during laryngoscopy maintained for 30 sec, surgical incision and 10min after surgical incision.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Patients aged 18–95 years, American Society of Anesthesiologists Physical Status I–III, scheduled for elective thyroidectomy at CHU of Liège.
    E.4Principal exclusion criteria
    Participants will be excluded if they had a heart failure with left ventricular ejection fraction < 35%, renal insufficiency (creatinine clearance < 40 mL/min), neuromuscular diseases or atrioventricular block.
    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint will be the target concentration of Propofol TCI to achieve a state entropy value between 50-60.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The target concentration of Propofol (TCI) to achieve a state entropy value between 50-60 (primary endpoint). State Entropy and Response Entropy values before anesthesia and then every 2.5 minutes until 10 min after surgical incision.
    E.5.2Secondary end point(s)
    Secondary endpoints were the evaluation of
    PPI before endotracheal intubation, PRD during laryngoscopy and surgical incision, morphine consumption in the recovery room and total morphine consumption at day-1, incidence of side effects related to morphine consumption at day-1, such as postoperative nausea and vomiting.
    E.5.2.1Timepoint(s) of evaluation of this end point
    Before endotracheal intubation, PRD during laryngoscopy and surgical incision.
    Morphine consumption in the recovery room and total morphine consumption at day-1, incidence of side effects related to morphine consumption at day-1, such as postoperative nausea and vomiting.

    The originality of our study is that it is the first randomized superiority trial concerning magnesium sulfate infusion regarding its hypnotic component. If the hypothesis proves to be true, we could improve the hypnotic drugs sparing during total intravenous general anesthesia for total thyroidectomy.
