About this study

Official title: Randomized Controlled Doubleblind Pilot Study Comparing Analgosedation Concepts During Placement of Regional Anaesthesia With Either Fentanyl, Remifentanil, Clonidine, EMLA-Patch or Placebo in Regard of Pain Reduction.

Aim of the study is to specify the best analgosedation technique during placement of regional anaesthesia from the patients' view.

In this double blind randomized trial the investigators will be testing the application of drugs administered intravenously (fentanyl-bolus, remifentanil-infusion, clonidine-bolus) or transcutaneously (EMLA salve) or placebo (NaCl 0,9% i.v. and skin protection salve).

Read the detailed description

In this doubleblind randomized pilot trial, patients will receive one of five possible combinations to assess which medication leads to the best medication during placement of regional anaesthesia. This assessement includes NRS, patients' satisfaction and wellbeing. The tested substances will be administered intravenously (fentanyl-bolus, remifentanil-infusion, clonidine-bolus) or transcutaneously (EMLA salve). The fifth combination will be the control group with only placebo medication. We expected to get first information for objectifying analgosedation during placement of regional anaesthesia for the conduction of further studies in this field.

Being tested
Fentanyl, Remifentanil, Clonidine, EMLA Cream, Placebo iv

What is being measured

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

  1. Pain intensity during placement of the regional anaesthesia

    Pain assessment during placement of the regional anaesthesia with the Numeric Rating Scale (NRS 1 to 10, with 1=lowest pain score, 10=highest pain score). Lower NRS describes a better outcome.

    Measured: 1 day

Secondary outcomes (2)
  1. Patients' wellbeing

    Wellbeing assessment during placement of the regional anaesthesia with the anaesthesiological questionnaire (ANP anaesthesiological Questionnaire is a self-rating method for the assessment of postoperative complaints, patient wellbeing and satisfaction. The rating scales from 0 to 3, with 0="none" and 3="strongly"). Higher wellbeing values represent a better outcome.

    Measured: 1 day

  2. Complication rate (delirium, allergic reactions, cardiopulmonary decompensation)

    Complications on operation day will be recorded and compared between the treatment groups.

    Measured: Through study completion, an average of 1 day

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Fentanyl, Remifentanil and Clonidine in people with Knee Arthropathy and Hip Arthritis, run by Medical University of Graz at 1 site in Austria.

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 2 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: finished, as of the sponsor's last update on 21 Oct 2019. 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 Austria. 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. Some participants in this study may receive a placebo. 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?

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?

Pain intensity during placement of the regional anaesthesia (time frame: 1 day). 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 21 Oct 2019.
