  Purpose

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.

Primary Outcome Measures:
  • 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. ] [ Designated as safety issue: No ]
    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).

Arms Assigned Interventions
Experimental: Ondansetron administration group Dietary Supplement: administration of ondanstron and screening of genomic DNA
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).
