[Variation in closeness to reality of standardized resuscitation scenarios : Effects on the success of cognitive learning of medical students].
Simulation often relies on a case-based learning approach and is used as a teaching tool for a variety of audiences. The knowledge transfer goes beyond the mere exchange of soft skills and practical abilities and also includes practical knowledge and decision-making behavior; however, verification of knowledge or practical skills seldom unfolds during simulations. Simulation-based learning seems to affect many learning domains and can, therefore, be considered to be multifactorial in nature. At present, studies examining the effects of learning environments with varying levels of reality on the cognitive long-term retention of students are lacking. ⋯ For simulation-based learning the outcome depends not only on knowledge, practical skills and motivational variables but also on the onset of negative emotions, perception of own ability and personality profile. Simulation training alone does not appear to guarantee learning success but it seems to be necessary to establish a simulation setting suitable for the education level, needs and personality characteristics of the students.

Randomized Controlled Trial Comparative Study
To what extent can local anesthetics be reduced for infraclavicular block with ultrasound guidance?
To assess the adequacy of different amounts of local anesthetics (LA) in infraclavicular blockade (ICB) under ultrasonographic (US) guidance and neurostimulation and compare them to the conventional doses under neurostimulation (NS). ⋯ The results show that US guidance is more effective in maintenance of successful ICB than neurostimulation guidance alone and a reduction of LA doses even to 70% of conventionally used doses seems possible with US guidance. This article is published in English.

[Guidance of axillary multiple injection technique for plexus anesthesia : Ultrasound versus nerve stimulation.]
Ultrasound guidance is still a young method in regional anesthesia when compared to nerve stimulation and only a few studies exist comparing these two techniques in an axillary multiple injection approach. ⋯ Nerve stimulation-guided axillary plexus blocks performed by trained anesthesiologists may result in similar onset times and success rates compared to ultrasound-guided blocks.

Randomized Controlled Trial Comparative Study
Lateral spread response monitoring during microvascular decompression for hemifacial spasm : Comparison of two targets of partial neuromuscular blockade.
The aim of the present study was to determine (1) whether successful intraoperative electromyography monitoring for lateral spread response (LSR) is possible with partial neuromuscular blockade (NMB) in subjects undergoing microvascular decompression (MVD) for hemifacial spasm and (2) the adequate level of NMB to achieve that goal. ⋯ Maintenance of partial NMB with a target T1/Tc ratio of 50 % resulted in a clinically acceptable success rate of LSR monitoring and surgical condition during MVD. Maintenance of partial NMB with a target T1/Tc ratio of 50 % rather than TOF count of two during LSR monitoring for MVD can therefore be recommended.

["Jump in at the deep end" : Simulator-based learning in acute care.]
With high-fidelity simulators in a modern blended learning setting, students are able to acquire knowledge and practical skills in acute medicine in realistic scenarios. However, it has not yet been clarified if the sequence of linking between knowledge and simulator-based training of practical skills plays an important role for increasing knowledge, for the self-concept and learning emotions of trainees. ⋯ In the context of simulation-based teaching, the learning outcome not only depends on knowledge, practical skills and motivational variables but also on the presence of negative feelings, ability self-concepts and various personality traits. There was a trend which showed that simulation in the field of anesthesiology and emergency medicine should be set up with the theoretical basis first in order to avoid negative feelings.
