About this study

Official title: The Effect of Premedication With Melatonin on Postoperative Recovery From Bariatric Surgery: a Prospective Randomised Controlled Cohort Study

Melatonin has sedative, hypnotic and analgesic properties that make it a good premedication agent before anesthesia and surgery.

In this study the investigators intend to randomise 60 patients undergoing bariatric surgery into two groups. The participants will receive either melatonin or placebo on the evening prior to the surgery, and the same agent two hours before the surgery.

The patients recovery from the surgery and anesthesia will be assessed using the Q0R15 questionnaire. The patients will be asked to take the questionnaire once in the pre-operative clinic, again after the second melatonin or placebo pill before entering the operating room, and once more on the first post-operative day.

Read the detailed description

Melatonin has sedative, hypnotic, analgesic, antiinflammatory, and chronobiologic properties that make it a good premedication agent before anesthesia and surgery. Patients undergoing surgery in our establishment usually receive benzodiazepines as premedicants to reduce anxiety before the surgery. For bariatric patients benzodiazepines are usually avoided due to side effects which could be deleterious in obese patients.

In this study the investigators intend to randomise 60 patients undergoing bariatric surgery into two groups. The participants will receive either melatonin or placebo on the evening prior to the surgery, and the same agent two hours before the surgery.

The patients recovery from the surgery and anesthesia will be assessed using the Q0R15 questionnaire. The patients will be asked to take the questionnaire once in the pre-operative clinic, again after the second melatonin or placebo pill before entering the operating room, and once more on the first post-operative day.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Melatonin in people with Recovery From Bariatric Surgery, run by Sheba Medical Center at 1 site in Israel.

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 27 Apr 2017. 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 Israel. 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?

Quality of recovery after surgery (time frame: First post operative day). 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 NCT02424071, which also lists 4 linked publications.

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 27 Apr 2017.
