About this study

Official title: Effects of Dexmedetomidine on Periprocedural Pain During Radiofrequency Ablation of Liver and Kidney Tumours

The purpose of he study is to evaluate effects of dexmedetomidine on pain during radiofrequency ablation of liver and kidney tumours.

Read the detailed description

Although radiofrequency ablation (RF) is accepted as the best therapeutic choice for patients with early stage hepatocellular carcinoma when liver transplantation or surgical resection are not suitable options, it is still performed only in a few hospitals and experience is so far limited (Goldberg \& Ahmed, 2002; Shiina et al., 2005). In addition, RF ablation is emerging as a viable alternative to surgery for inoperable patients with limited hepatic metastatic disease, especially from colorectal cancer. Although radiofrequency ablation has been accepted as a safe and effective treatment for liver and kidney tumours, there are few studies addressing periprocedural pain.

Thus, the optimal anaesthetic procedure is still to be determined. Currently at our institution RF is performed as monitored sedation procedure using remifentanil infusion supplemented with midazolam boluses, when considered necessary. However, when using remifentanil and midazolam combination it is quite difficult to avoid too deep respiratory depression.

Dexmedetomidine is an α2-adrenoreceptor agonist with sedative, analgesic and anxiolytic effects, and it has more selective α2-adrenergic effect than clonidine. Dexmedetomidine has a great deal of potential in this arena given its analgesic and anxiolytic properties while preserving respiratory drive (Bergese SD et al., 2010).

All patients will receive dexmedetomidine 0.4 µg/kg/hr infusion from the start of procedure. The infusion will be continued during the whole RF procedure.

At the same time all patients will receive remifentanil infusion according to TCI (target controlled infusion) protocol. Plasma concentration target will be set from 0.5 ng/ml and, if necessary, will be increased to achieve a comfortable state of patient (Ramsey Sedation Scale: 2-3).

What is being measured

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

  1. Patient Satisfaction With Sedation Technique

    Rating of how satisfied the patient was with their sedation on a scale of 1-5 with 1 being very dissatisfied and 5 being extremely satisfied

    Measured: After completion of procedure (within 15 minutes)

Secondary outcomes (3)
  1. Vital signs: blood pressure, oxygen saturation, heart rate, breathing rate

    Measured: During procedure and up to 2 hours stay at the post-anesthesia care unit

  2. Ramsey Sedation Scale Score

    Rating of depth of sedation. Scale 1 - 6, 1 being wide awake and 6 being non-responsive

    Measured: During the procedure and up to 2 hours stay at the post-anesthesia care unit

  3. Maximal pain intensity

    The 11-point Numerical Rating Scale (NRS) to assess periprocedural pain. Scale of 0-10, with 0:no pain and 10: pain as bad as it could be

    Measured: During procedure and up to 2 hours stay at the post-anesthesia care unit

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dexmedetomidine in people with Cancer of Kidney and Renal Pelvis and Cancer of Liver, run by Uppsala University Hospital 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 2 inclusion and 6 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 17 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?

Patient Satisfaction With Sedation Technique (time frame: After completion of procedure (within 15 minutes)). 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 17 Dec 2014.
