The introduction of serotonin antagonists as antiemetics for prophylaxis of chemotherapy-induced nausea and vomiting represented a major step toward better patient tolerance and adherence to this type of treatment. Several published trials compared different serotonin antagonists without demonstrating clear superiority of any one of them. Because most of these trials compared ondansetron with granisetron, the authors conducted a meta-analysis to determine if the current data available show any therapeutic difference between them. ⋯ The authors conclude that both granisetron and ondansetron have similar antiemetic efficacy for prophylaxis of chemotherapy-induced nausea and vomiting. Because the number of comparative studies that addressed the delayed nausea and vomiting scenarios is low, further RCTs are still needed to confirm these results.

Meta AnalysisComplementary and alternative medicine in the management of pain, dyspnea, and nausea and vomiting near the end of life. A systematic review.
To review the evidence for efficacy of complementary and alternative medicine (CAM) modalities in treating pain, dyspnea, and nausea and vomiting in patients near the end of life, original articles were evaluated following a search through MEDLINE, CancerLIT, AIDSLINE, PsycLIT, CINAHL, and Social Work Abstracts databases. Search terms included alternative medicine, palliative care, pain, dyspnea, and nausea. Two independent reviewers extracted data, including study design, subjects, sample size, age, response rate, CAM modality, and outcomes. ⋯ Because of publication bias, trials on CAM modalities may not be found on routine literature searches. Despite the paucity of controlled trials, there are data to support the use of some CAM modalities in terminally ill patients. This review generated evidence-based recommendations and identified areas for future research.

Meta Analysis
Efficacy of 5-HT3 receptor antagonists in radiotherapy-induced nausea and vomiting: a quantitative systematic review.
5-HT3 receptor antagonists are used to treat radiation-induced sickness. The purpose of this study was to define anti-emetic efficacy and potential for harm of these drugs in radiotherapy. A systematic search, critical appraisal and quantitative analysis of relevant data using the number-needed-to-treat or harm (NNT/H) were conducted. ⋯ The evidence for nausea was less clear. There was no evidence that these drugs are of any benefit beyond 24 h. There was evidence that they produce specific adverse effects.

Meta AnalysisRationale for the use of a single fixed intravenous dolasetron dose for the prevention of cisplatin-induced nausea and vomiting. Pooled analysis of 14 clinical trials.
Dolasetron mesilate is a selective 5-HT3 receptor antagonist that prevents chemotherapy-induced and postoperative nausea and vomiting. For the majority of patients in intravenous dolasetron trials for chemotherapy-induced nausea and vomiting, dosing has been based on body weight (mg/kg). The approved weight-based dose is 1.8 mg/kg based on results of controlled clinical trials. ⋯ Fixed-dose groups were established at doses of 50, 75, 100, 125, 150, and 200 mg. Doses less than or equal to the midpoint between two dose groups were included in the lower dose group. Pooled results showed that the 100 mg intravenous dolasetron dose group (who received actual doses of 88-112 mg) produced the highest rate (53%) of complete response (0 emetic episodes and no rescue medication in the 24-h period following initiation of chemotherapy).

Meta Analysis Comparative Study
A meta-analysis of nausea and vomiting following maintenance of anaesthesia with propofol or inhalational agents.
A number of prospective randomized comparator studies have suggested that there is a reduction in post-operative nausea and vomiting following maintenance of anaesthesia with propofol compared with inhalational agents. We analysed these studies in more detail by examining the effects of induction agent, choice of inhalation agent, presence/absence of nitrous oxide, age of patient or use of opiate on the incidence of emesis. ⋯ These were examined individually and independently by two of the authors and log-odds ratios, calculated from the incidence data of each individual trial, were determined and combined using a fixed-effects meta-analysis approach. Patients who received maintenance of anaesthesia with propofol had a significantly lower incidence of post-operative nausea and vomiting in comparison with inhalational agents regardless of induction agent, choice of inhalation agent, presence/absence of nitrous oxide, age of patient or use of opiate.
