Postoperative nausea and vomiting after general anesthesia is one of the common anesthetic complications. If the patient is discharged from the hospital after surgery, proper treatment may be delayed or impossible if nausea and vomiting occurred. Thus, it is necessary to prevent these symptoms beforehand. Patients who underwent day-surgery will be treated with prophylactic ramosetron orally disintegrating tablets to determine whether the frequency of nausea and vomiting is decreased when the patient returned home after discharge.
