Brief summary
Ramosetron is effective in preventing postoperative nausea and vomiting. Several studies reported that ramosetron is also effective treatment of irritable bowel syndrome. The investigators examine the effect of ramosetron on postoperative bowel motility.
Detailed description
Ramosetron, a new potent and long-acting selective 5-HT3(5-hydroxytryptamine3) receptor anatagonist, is effective for preventing postoperative nausea and vomiting. Also several studies reported that ramosetron is effective treatment of diarrhea-predominant irritable bowel syndrome because it inhibits the accelerated colonic transit, abnormal colonic water transport, defecation abnormality, and the lowered colonic perceptual threshold by corticotrophin-releasing hormone, There is no study about the effect of ramosetron used for preventing postoperative nausea and vomiting on postoperative bowel motility. In this study, the investigators examine the effect of ramosetron on postoperative bowel motility.
Interventions
Administer 2 ml of normal saline iv before induction. Inject ramosetron 0.3 mg iv at the end of surgery. Add ramosetron 0.6 mg to the iv PCA.
Administer dexamethasone 10 mg iv before induction. Inject 2 ml of normal saline iv at the end of surgery. Add 4 ml of normal saline to the iv PCA.
