About this study

Official title: Perianal Nerval Block in Proctological Interventions: a Prospective Randomized Double Blinded Study

The aim of this study is to evaluate whether a local perianal block performed during a proctological intervention can reduce the postoperative pain.

Read the detailed description

The aim of this study is to evaluate whether a local perianal block performed during a proctological intervention can reduce the postoperative pain.

All patients will undergo surgery under general or spinal anesthesia. At the end of the surgery, the surgeon will perform a perianal block using the local anesthetic or the placebo upon randomisation. The experimental group will receive a local anesthetics and the control group a normal saline injection. All injections will be perianal, peripheral to the external anal sphincter.

Being tested
Placebo 40 mL Saline 0.9%, 40 mL Ropivacain 0.5%
Medical subject headings
Fissure in Ano, Hemorrhoids

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing 40 mL Ropivacain 0.5% in people with Perianal Fistula and Fissure in Ano, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

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 10 Jul 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 Switzerland. 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?

Postoperative Pain (time frame: 24 hours post-surgery). 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 NCT03405922, 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 10 Jul 2019.
