Association of 5-HT3 Receptor Gene Polymorphism With the Efficiency of Ondansetron for Postoperative Nausea and Vomiting
August 3, 2012 updated by: Yonsei University
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.

Intervention / Treatment |
---|---|
Experimental: Ondansetron administration group
|
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).
