About this study

Postoperative pain, the great concern for the patients undergoing spine surgery, has led to common use of opioid-based intravenous patient-controlled analgesia (IV-PCA) postoperatively. Opioid-based IV-PCA offers better pain control, which could facilitate early recovery, rehabilitation and increase patient satisfaction. However, its use inevitably increases the incidence of postoperative nausea and vomiting (PONV), another great discomfort, as high as 80% in patients with multiple risk factors.Therefore, there have been consistent efforts to prevent PONV with multimodal therapies such as risk stratification, modification and preventive use of antiemetics.

Of all antiemetics, 5-hydroxytryptamine (5-HT3) antagonist, especially ondansetron, is most commonly used and extensively studied to reduce PONV because of its efficacy and fewer side effects.[8] However, its efficacy is not quite satisfactory when it comes to PONV associated with opioid-based IV-PCA. Recently, there are many reports comparing the antiemetic efficacy between ondansetron and the 2 newly developed 5-HT3 antagonists, ramosetron and palonosetron. Ramosetron is known to have a higher affinity and longer duration of binding to 5-HT3 receptor, therefore exhibits potent and sustained anti-emetic effect than previously developed 5-HT3 antagonists.Palonosetron has a unique allosteric binding to the 5-HT3 receptor, which brings a higher affinity, longer duration of action and longer elimination half-time.According to the previous studies, both ramosetron and palonosetron showed superior antiemetic efficacy for PONV associated with opioid-based IV-PCA to ondansetron as expected by their theoretical advantages. However, it has never been evaluated which one has superior antiemetic efficacy for opioid-based IV-PCA associated PONV. Therefore, in this study, we tried to evaluate the relative antiemetic efficacy of ramosetron and palonosetron in controlling opioid-based IV-PCA related PONV.

What participants receive

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

  • ramosetronDrug

    Ramosetron 0.3 mg was mixed to the PCA. Same dose of drug was administered 10 minutes before the end of surgery according to the allocated group.

  • palonosetronDrug

    palonosetrno 0.075 mg was mixed to the PCA. Same dose of drug was administered 10 minutes before the end of surgery according to the allocated group.

What is being measured

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

  1. verbal numeric scale

    At each time point, frequency and intensity (verbal numeric scale, 0-10, 0: no nausea, 10: maximum) of nausea, frequency of vomiting, rescue antiemetic use were recorded and compared between groups.

    Measured: change of antiemetic efficacy for 5 time points ( postanesthesia care unit, 0-6 h, 6-24 h, 24-48 h, 48-72 h after operation)

Questions about this trial

What is this clinical trial studying?

A study testing ramosetron and palonosetron in people with Postoperative Nausea and Vomiting, run by Yonsei University.

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 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 19 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

verbal numeric scale (time frame: change of antiemetic efficacy for 5 time points ( postanesthesia care unit, 0-6 h, 6-24 h, 24-48 h, 48-72 h after operation)). 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 19 Feb 2014.
