Multicenter Study Comparative Study Clinical Trial
Feasibility of closed-loop co-administration of propofol and remifentanil guided by the bispectral index in obese patients: a prospective cohort comparison†
Closed-loop delivery of total intravenous anesthesia with propofol and remifentanil, guided by BIS, is feasible in obese patients.

Randomized Controlled Trial Multicenter Study Observational Study
Dynamic preload markers to predict fluid responsiveness during and after major gastrointestinal surgery: an observational substudy of the OPTIMISE trial.
Stroke volume variation (SVV) and pulse pressure variation (PPV), termed dynamic markers of preload responsiveness, may predict the response to i.v. fluid in critically ill patients. However, the predictive accuracy of these variables during gastrointestinal surgery remains uncertain. ⋯ In this study, the predictive accuracy of SVV and PPV for fluid responsiveness was insufficient to recommend for routine clinical use during or after major gastrointestinal surgery.

Randomized Controlled Trial Multicenter Study
Pre-emptive treatment with fibrinogen concentrate for postpartum haemorrhage: randomized controlled trial.
In early postpartum haemorrhage (PPH), a low concentration of fibrinogen is associated with excessive subsequent bleeding and blood transfusion. We hypothesized that pre-emptive treatment with fibrinogen concentrate reduces the need for red blood cell (RBC) transfusion in patients with PPH. ⋯ ClinicalTrials.gov: http://clinicaltrials.gov/show/NCT01359878.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of vestipitant with ondansetron for the treatment of breakthrough postoperative nausea and vomiting after failed prophylaxis with ondansetron.
Postoperative nausea and vomiting (PONV) is common; ondansetron is often used as prophylaxis or for breakthrough episodes. Vestipitant is a neurokinin 1 (NK-1) receptor antagonist that is effective for prophylaxis, but its efficacy for treating established PONV is unknown. This study was performed to evaluate the efficacy and safety of vestipitant, compared with ondansetron for the treatment of breakthrough PONV in patients who had already received prophylactic ondansetron before surgery. ⋯ NCT01507194.

Randomized Controlled Trial Multicenter Study
Methylnaltrexone to prevent intrathecal morphine-induced pruritus after Caesarean delivery: a multicentre, randomized clinical trial.
Intrathecal morphine-induced pruritus is a very common side-effect that is difficult to prevent or treat. Central and peripheral mechanisms are believed to be involved. The aim of this study was to determine if a peripherally acting, μ-opioid antagonist would reduce morphine-induced pruritus. ⋯ Australian New Zealand Clinical Trials Registry (ACTRN12611000345987).
