Randomized Controlled TrialMinimum alveolar concentration threshold of sevoflurane for postoperative dream recall.
Many factors affect postoperative dream recall, including patient characteristics, type of anesthesia, timing of postoperative interview and stress hormone secretion. Aims of the study were to determine whether Bispectral Index (BIS)-guided anesthesia might decrease sevoflurane minimum alveolar concentration (MAC) when compared with hemodynamically-guided anesthesia, and to search for a MAC threshold useful for preventing arousal, dream recall and implicit memory. ⋯ BIS-guided anesthesia was not able to generate different MAC values compared to HP-guided anesthesia. Independent of the guide used for anesthesia, a sevoflurane MAC over 0.9 was required to prevent postoperative dream recall.

We present a review of the hemodynamic management of septic shock. Although substantial amount of evidence is present in this area, most key decisions on the management of these patients remain dependent on physiological reasoning and on pathophysiological principles rather than randomized controlled trials. During primary (early) resuscitation, restoration of adequate arterial pressure and cardiac output using fluids and vasopressor and/or inotropic drugs is guided by basic hemodynamic monitoring and physical examination in the emergency department. ⋯ No specific hemodynamic treatment strategy, be it medications including fluids, monitoring devices or treatment algorithms has yet been proved to improve outcome. Moreover, there is virtually no data on the optimal management of the resolution phase of septic shock. Despite these gaps in knowledge, the data from observational studies and trials suggests that mortality in septic shock has been generally decreasing during the last decade.

Multicenter StudyInternational survey on the management of mechanical ventilation during extracorporeal membrane oxygenation in adults with severe respiratory failure.
No consensus exists on the optimal settings of mechanical ventilation during veno-venous extracorporeal membrane oxygenation (ECMO). Our aim was to describe how mechanical ventilation and related interventions are managed by adult ECMO centres. ⋯ We found large variability in ventilatory practices during ECMO. The clinicians' training background and the centres' experience had no influence on the approach to ventilation. This survey shows that well conducted studies are necessary to determine the best practice of mechanical ventilation during ECMO and its impact on patient outcome.
