Multicenter Study
Influence of transactive memory on perceived performance, job satisfaction and identification in anaesthesia teams.
There is an increasing awareness in the medical community that human factors are involved in effectiveness of anaesthesia teams. Communication and coordination between physicians and nurses seems to play a crucial role in maintaining a good level of performance under time pressure, particularly for anaesthesia teams, who are confronted with uncertainty, rapid changes in the environment, and multi-tasking. The aim of this study was to examine the relationship between a specific form of implicit coordination--the transactive memory system--and perceptions of team effectiveness and work attitudes such as job satisfaction and team identification. ⋯ These findings provided empirical evidence of the existence of a transactive memory system among real anaesthesia teams, and highlight the need to investigate whether transactive memory is actually linked with objective measures of performance.

This pilot study in five healthy adult humans forms the pre-clinical assessment of the effect of a forced convective head cooling device on intracranial temperature, measured non-invasively by magnetic resonance spectroscopy (MRS). ⋯ Convective head cooling reduced MRS brain temperature and core brain was cooled.

Randomized Controlled Trial Comparative Study
Comparison of a new neuromuscular transmission monitor compressomyograph with mechanomyograph.
We developed a new neuromuscular transmission monitor, the compressomyograph (CMG, European patent number: EP 06018557.6, US patent number: US 60/824.541). This is the first preliminary report comparing neuromuscular block monitored by CMG and the Relaxometer mechanomyograph (MMG). ⋯ The CMG could be a reliable clinical monitor in the daily anaesthesia practice that does not require time to set up or rigid support of the arm.

Randomized Controlled Trial
Effects of colloid and crystalloid solutions on endogenous activation of fibrinolysis and resistance of polymerized fibrin to recombinant tissue plasminogen activator added ex vivo.
The study was conducted to explore the effects of colloid and crystalloid solutions on activation of fibrinolysis during orthopaedic surgery and to determine whether fluids facilitate clot dissolution at a particular fibrinolytic activity. ⋯ The type of i.v. fluid used does not influence endogenously occurring fibrinolytic activity in patients undergoing major orthopaedic surgery. However, during hyperfibrinolysis, the presence of HES or gelatin solution facilitates clot disintegration to a greater extent than Ringer's lactate solution, because the weaker clots formed with colloids dissolve faster.
