Review Meta AnalysisThe efficacy of 5-HT3 receptor antagonists for the prevention of postoperative nausea and vomiting after craniotomy: a meta-analysis.
The purpose of this meta-analysis was to assess the efficacy of prophylactic administration of 5-HT3 receptor antagonists for postoperative nausea and vomiting in neurosurgical patients at 24 and 48+ hours. After a systematic search, 7 published randomized placebo controlled trials involving 448 craniotomy patients (222 treatment, 226 control) were included in the meta-analysis. Study drugs included ondansetron, granisetron, and tropisetron. ⋯ There were no differences between the treatment and control groups in the cumulative incidence of nausea at 24 hours (RR=0.76, 95% CI: 0.54-1.06) and 48+ hours (RR=0.81, 95% CI: 0.62-1.06). The cumulative incidence of both nausea and vomiting continued to increase after 24 hours in both groups. Despite the ability of 5-HT3 receptor antagonists to reduce emetic episodes, future investigations should seek to address the control of postoperative nausea and to reduce further postoperative emesis in this population.

Meta Analysis Comparative StudyPropofol [correction of propfol] versus methohexital for electroconvulsive therapy: a meta-analysis.
A systematic search (Medline, Cochrane library, Embase, bibliographies, to 5.2000, no language restriction) was performed for published reports of randomized comparisons of propofol and methohexital for anesthesia during electroconvulsive therapy. We analyzed 15 trials with data on 706 patients. The duration of motor seizure was shorter with propofol (range, 18-39 seconds) than with methohexital (range, 26-48 seconds, weighted mean difference 8.4 seconds [95% CI, 6.6-10.0]). ⋯ Data on adverse effects were sparse. Duration of seizure was not proven to be a useful measure of treatment success in the study of electroconvulsive therapy with propofol or methohexital. The impact of the technique of anesthesia on the underlying disease needs to be established.
