Post Operative Nausea and VomitingNCT01657786
Association of 5-HT3 Receptor Gene Polymorphism With the Efficiency of Ondansetron for Postoperative Nausea and Vomiting
A study testing administration of ondanstron and screening of genomic DNA in people with Post Operative Nausea and Vomiting, run by Yonsei University at 1 site in South Korea.
Trial summary
Postoperative nausea and vomiting (PONV) is a common and distressing complication in patients undergoing general anesthesia. However, although 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists have significantly reduced PONV, it is reported that over 35% of patients treated with ondansetron experience PONV.

About this study
Postoperative nausea and vomiting (PONV) is a common and distressing complication in patients undergoing general anesthesia. However, although 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists have significantly reduced PONV, it is reported that over 35% of patients treated with ondansetron experience PONV. Though the cause of failure in ondansetron treatment is not clear, the investigators assumed that polymorphism in the 5-HT3 receptor gene would contribute to such inter-individual variation. In this study, the investigators examine whether the polymorphisms of 5-HT3 receptor gene affect the efficacy of ondansetron to prevent PONV in patients undergoing general anesthesia for laparoscopic surgery.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
administration of ondanstron and screening of genomic DNADietary supplement
Thirty minutes before the end of surgery, ondansetron 0.1 mg/kg is administered intravenously. We assess an episode of PONV at first 2 h and 2-24 h after surgery. Genomic DNA was prepared and screened. The incidence of PONV is compared among genotypes in 5-HT3 receptor gene polymorphisms (5-HT3a: S253N; 5-HT3b: Y129S, -100_-102delAAG).

What is being measured
The primary outcome is the main question the study is designed to answer.
The relationship between the incidence of PONV after ondansetron administration and genotypes in 5-HT3 receptor gene polymorphisms ((5-HT3a: S253N; 5-HT3b: Y129S, -100_-102delAAG)
The incidence of PONV after ondansetron administration is compared among genotypes in 5-HT3 receptor gene polymorphisms (5-HT3a: S253N; 5-HT3b: Y129S, -100_-102delAAG).
Measured: at first 2 h and 2-24 h after surgery.

Where is the study taking place?
The record lists 1 site in South Korea. 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. 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?
The relationship between the incidence of PONV after ondansetron administration and genotypes in 5-HT3 receptor gene polymorphisms ((5-HT3a: S253N; 5-HT3b: Y129S, -100_-102delAAG) (time frame: at first 2 h and 2-24 h after surgery.). 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 6 Aug 2012.
