About this study

Official title: A Randomized Placebo-Controlled Study of Whether Pre-operative Pregabalin 300 mg Will Improve Pain Control in Patients Undergoing Laparoscopic Roux-en-Y Gastric Bypass (Bariatric Surgery)

Randomized clinical trial to evaluate whether a single pre-operative dose of Pregabalin will alleviate post-operative pain and decrease post-operative analgesic requirements in morbidly obese patients undergoing laparoscopic gastric bypass surgery.

Read the detailed description

Pregabalin is a popular adjunct for relieving neuropathic pain in diabetics. There have been multiple studies evaluating its use in pre and post-operative pain control in various surgeries. Post-operative pain control is a challenging problem in bariatric patients due to the high doses of narcotic required, related to the high body mass, and the danger of concomitant respiratory depression. In the obese patient, the goal of postoperative pain management is provision of comfort, early mobilization and improved respiratory function, without causing inadequate pain control, respiratory compromise or increased nausea.

Methods: A Randomized Controlled Trial, whereby patients undergoing Laparoscopic Roux-en-Y gastric bypass will be administered a single pre-operative dose of Pregabalin or a placebo. We plan to follow their immediate post-operative course in the hospital, with regard to the following primary endpoints:

  • Post-operative analgesic requirements
  • Post-operative pain scale (rated 0-10)
  • Episodes of vomiting
  • Post-operative antiemetic requirement
  • Length of stay
Being tested
Pregabalin, Placebo (for Pregabalin)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Pregabalin in people with Post-operative Pain, run by Legacy Health System 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 1 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 14 Jul 2022. 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 6 Jun 2022). 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?

Post-operative Pain Medication Requirements (time frame: Morphine milligram equivalent opioid requirements on post op days zero, 1, and 2.). 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 14 Jul 2022.
