About this study

The purpose of the study is to determine whether remifentanil influence the pharyngeal phase of swallowing using using pressure and impedance recordings. The purpose is also to compare remifentanil to morphine and younger to elderly volunteers.

Read the detailed description

Remifentanil and other opioids are widely used as anesthetic sedation during minor surgical procedures and as pain relief in postoperative patients when the patient is spontaneously breathing and the airway is not secured by endotracheal intubation. In a previous study (not yet published) we showed that remifentanil induce pulmonary aspiration in healthy volunteers and the aim of this study is to objectively determine weather remifentanil infusion in healthy volunteers influence the pharyngeal phase of swallowing. The purpose is also compare the effect of remifentanil to morphine and younger volunteers to elderly volunteers. To assess this question we are going to study 24 volunteers, 12 younger and 12 elderly, who are randomised to receive remifentanil infusion with target concentration 3 ng/ml during 30 minutes at one occasion and an injection of morphine (younger: 0.1 mg/kg, elderly 0.07 mg/kg) at the other. The volunteers are asked to swallow 10 ml normal saline several times both before and after opioid administration and pharyngeal motility is parallelly recorded using combined manometry and impedance catheter placed transnasally into to the pharyngo-esophageal segment. Any subjective swallowing difficulties are also recorded.

What is being measured

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

  1. Pressure-Flow Variables measured by combined manometry and impedance system ( ManoScan 360) during pharyngeal swallowing

    Measured: up to 30 minutes after opioidadministration (after start of remifentanil infusion or morphine injection)

Secondary outcomes (1)
  1. Subjective swallowing difficulties measured by 4-point scale

    Measured: Variables are measured before (baseline) and 15 min and 30 minutes after opioidadministration (after start of remifentanil infusion or morphine injection)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Morphine and Remifentanil in people with Pharyngeal Dysfunction and Pharyngeal Swallowing, run by Region Örebro County at 1 site in Sweden.

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 3 inclusion and 7 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 3 Dec 2014. 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 Sweden. 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 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?

Pressure-Flow Variables measured by combined manometry and impedance system ( ManoScan 360) during pharyngeal swallowing (time frame: up to 30 minutes after opioidadministration (after start of remifentanil infusion or morphine injection)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01924234, which also lists 1 linked publication.

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 3 Dec 2014.
