Trial summary

The purpose of this study is to compare the analgesic efficacy and side effects induced by administration of two different infusion rates of remifentanil, 0,05 mcg/ Kg/ min versus 0,1mcg/ Kg/ min, in order to determine which one is the most appropriate analgesic treatment to face extracorporeal shock wave lithotripsy.

About this study

Official title: Total Intravenous Anaesthesia Using Remifentanil In Extracorporeal Shock Wave Lithotripsy (ESWL). Comparison of Two Dosages.

The purpose of this study is to compare the analgesic efficacy and side effects induced by administration of two different infusion rates of remifentanil, 0,05 mcg/ Kg/ min versus 0,1mcg/ Kg/ min, in order to determine which one is the most appropriate analgesic treatment to face extracorporeal shock wave lithotripsy.

Read the detailed description

Remifentanil is an ultra-short-acting oppioid, which is quickly metabolized by unspecific blood and tissue esterases . This feature vouches for a predictable pharmacokinetics and makes this drug suitable for administration in continuous intravenous infusion in order to achieve patient conscious sedation during non-invasive surgical procedures. Remifentanil could be particularly useful in day surgery setting, thanks also to its faster elimination than other oppioids. This property ensure a swift recovery from conscious sedation, reducing the period of time during which patient remains in recovery room and decreasing also the incidence of side effects, like PONV and respiratory depression. Conscious sedation with remifentanil can provide patient comfort and cooperation during surgical procedure, since the verbal contact with the patient is kept up. Extracorporeal shock wave lithotripsy (ESWL) is a non-invasive procedure, contemplated as the first-line treatment for renal and upper ureteral stones, if stone diameter is ranged from 5 to 20 mm . It can grind calculi into fine particles, that are expelled through micturition. Although many studies have been published in regard to continuous intravenous infusion of remifentanil, a small number of them focuses on which is the most appropriate infusion rate for ESWL procedure.

What participants receive

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

  • RemifentanilDrug

    Remifentanil is an ultra-short-acting oppioid, which is quickly metabolized by unspecific blood and tissue esterases

  • RemifentanilDrug

    GROUP A (N = 114): patients assigned to this group received Remifentanil at infusion rate of 0.05 mcg / kg / min I.V. ; GROUP B (N = 114): in this group Remifentanil was administered at infusion rate of 0,1 mcg / kg / min I.V. Remifentanil was administered intravenously throughout ESWL procedure.

What is being measured

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

  1. VAS score

    Before the beginning of ESWL and at the end of the treatment patient were asked to point out the intensity of pain they were feeling on an 11-points visual analog scale (VAS), ranged from 0 "no pain" to 10 "worst pain".

    Measured: Vas score was monitored up to the end of surgery, for about forty minutes

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Remifentanil in people with Kidney Calculi, run by University of Roma La Sapienza at 1 site in Italy.

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 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 17 Oct 2011. 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 Italy. 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?

VAS score (time frame: Vas score was monitored up to the end of surgery, for about forty minutes). 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 NCT01452880, 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 17 Oct 2011.
