About this study

Official title: THE CAT(H) STUDY CATHETER ANALGESIA TRIAL Phenazopyrdine vs. Placebo: a Randomized Controlled Trial A CREST 2010 Project

The primary aim of this randomized clinical trial is to compare the utility of phenazopyridine HCl vs. placebo in reducing catheter-associated discomfort during the post-operative period in the gynecologic patient using mean VAS measurments.

Read the detailed description

This is a randomized clinical trial to determine whether phenazopyridine HCl reduces catheter-related bladder discomfort, using mean VAS scores and overall pain medicine requirements in women catheterized following in-patient gynecologic surgery.

Hypothesis and Aims:

We plan to test the null hypothesis that there is no difference in post-operative pain as measured by VAS pain scores and pain medication requirements in women with a Foley catheter following gynecologic surgery that are given phenazopyridine HCl vs. placebo.

The primary aim of this randomized clinical trial is to compare the utility of phenazopyridine HCl vs. placebo in reducing catheter-associated discomfort during the post-operative period in the gynecologic patient using mean VAS measurements.

Being tested
phenazopyridine HCl, Placebo
Keywords
Phenazopyrdine, post operative bladder catheritization, VAS scores, Bladder pain related to indwelling foley catheters., Bladder irritaion related to indwelling foley catheters.

Study groups in NCT00771173
Study groupRoleWhat they receive
Study Medication GroupActive comparatorParticipants that are randomized to the phenazopyridine HCl group will receive the study medication (200 mg of phenzopyridine HCl orally) after leaving the operating room. We anticipate the first dose to be given after the patient has left the recovery area. We will continue use of study medication until it has been given up to 24 hours after the first VAS collection or catheter removal, whichever occurs first
Receives: Drug: phenazopyridine HCl
Placebo tablet GroupPlacebo comparatorFor participants randomized to the placebo group will follow the same dosing schedule for the study medication, although they will receive an inert placebo tablet.
Receives: Other: Placebo

What is being measured

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

  1. Reduction of Catheter-associated Discomfort During the Post-operative Period in the Gynecologic Patient Using Mean Visual Analogue Scale (VAS) Measurments

    The VAS measures bladder pain on a straight line from 0 to 10 in centimeters, where a mark of zero indicates no pain and a mark of 10 indicates worst possible pain. Mean VAS score was recorded for participants in the active treatment and placebo cohorts.

    Measured: 24 hours

Timeline

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing phenazopyridine HCl in people with Catheter-related Bladder Discomfort, run by Loyola University at 1 site in United States.

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 8 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 29 Sep 2016. 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 United States. 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?

Yes. Results are posted in the registry (first posted 11 Jun 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Reduction of Catheter-associated Discomfort During the Post-operative Period in the Gynecologic Patient Using Mean Visual Analogue Scale (VAS) Measurments (time frame: 24 hours). 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 NCT00771173, 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 29 Sep 2016.
