Randomized Controlled Trial Comparative Study Clinical Trial[Effect of concurrent use of ondansetron hydrochloride and dexamethasone against nausea and vomiting in lung cancer patients receiving cisplatin].
We examined the efficacy of concurrent use of ondansetron hydrochloride and dexamethasone, and the effective dose of dexamethasone against nausea and vomiting in lung cancer patients receiving chemotherapy including single high dose cisplatin. The study was carried out on total of 44 courses of chemotherapy in either initial onset or recurrence of lung cancer. The patients were given 4 mg of ondansetron injection on the day of cisplatin injection (Day 1), and 4 mg/day of ondansetron tablet for Days 2 to 4. ⋯ However, control of emesis was unfavorable in female patients on Day 1 and was still unfavorable even though dexamethasone was combined from Day 2. We considered from the above results that 10 mg/day of concurrent dexamethasone is sufficient in suppression of delayed emesis on Day 2. However, in order to improve nausea or food intake, or to suppress emesis in patients who are highly likely to show unfavorable control for Day 2 and onward, 20 mg/day should also be effective.

Randomized Controlled Trial Multicenter Study Clinical TrialOral granisetron as prophylaxis for nausea and vomiting during fluorescein angiography. A multicentre, double-blind, randomised, parallel group, placebo-controlled study.
Prophylaxis with oral Granisetron was assessed in patients undergoing fluorescein angiography (FAG) in order to evaluate its efficacy in reducing patients' discomfort due to nausea and vomiting (4% > 20%) and to ensure completion of the investigation. ⋯ The results suggest that Granisetron may be indicated as prophylaxis in patients undergoing FAG in order to prevent or control emesis, improve patients' comfort and ensure successful outcome of the investigation.

Randomized Controlled Trial Comparative Study Clinical TrialSingle-dose tropisetron for preventing postoperative nausea and vomiting after breast surgery.
In this randomized, double-blind, placebo-controlled study, we compared the efficacy of tropisetron 5 mg with tropisetron 2 mg for the prevention of postoperative nausea and vomiting (PONV) after breast surgery. One hundred forty-eight female patients were randomized to receive either tropisetron 5 mg (n = 49), tropisetron 2 mg (n = 49), or saline (n = 50) before the induction of anesthesia with thiopental and morphine. Anesthesia was maintained with nitrous oxide and isoflurane. Postoperative analgesia was provided by patient-controlled analgesia with i.v. morphine. The incidence of PONV, the pain score, and the analgesic requirement were recorded for 48 h. There was no difference among groups in patient characteristics, risk factors for PONV, morphine consumption, or side effects. During the first 6 h postoperatively, the incidence of PONV after tropisetron 2 mg and 5 mg were similar and were superior to placebo (P < 0.001). After 6 h, the incidence of PONV increased significantly in patients who had received tropisetron 2 mg (P = 0.01) and was greater than that in patients who had received tropisetron 5 mg (P = 0.001). We conclude that single-dose tropisetron 5 mg is more effective than tropisetron 2 mg in the prevention of PONV after breast surgery. ⋯ Breast surgery is associated with a high incidence of postoperative nausea and vomiting. A single dose of i.v. tropisetron 5 mg is well tolerated and decreases the number of vomiting and nausea episodes after surgery.

Randomized Controlled Trial Clinical TrialAcupressure for intrathecal narcotic-induced nausea and vomiting after caesarean section.
In this randomized double-blind trial we investigated the effect of acupressure on the incidence of nausea and vomiting after caesarean section under spinal anaesthesia with added intrathecal morphine. Parturients wore either acupressure or placebo wristbands during surgery and postoperatively for at least 10 h. ⋯ However, in the sub-group of parturients who gave a previous history of postoperative nausea or vomiting, there was a statistically significant reduction in both postoperative nausea and vomiting/retching in the acupressure group. Further investigations are needed to see whether acupressure may be an effective non-pharmacological, non-invasive treatment for a common problem in this sub-group of patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Antiemetic activity of propofol after sevoflurane and desflurane anesthesia for outpatient laparoscopic cholecystectomy.
Controversy exists regarding the effectiveness of propofol to prevent postoperative nausea and vomiting. This prospective, randomized, single-blinded study was designed to evaluate the antiemetic effectiveness of 0.5 mg/kg propofol when administered intravenously after sevoflurane- compared with desflurane-based anesthesia. ⋯ A subhypnotic intravenous dose of propofol (0.5 mg/kg) administered at the end of outpatient laparoscopic cholecystectomy procedures was more effective in preventing postoperative nausea and vomiting after a sevoflurane-based (compared with a desflurane-based) anesthetic.
