Randomized Controlled TrialInfluence of Airway Trolley Organization on Efficiency and Team Performance: A Randomized, Crossover Simulation Study.
Failed management of unanticipated difficult airway situations contributes to significant anesthesia-related morbidity and mortality. Optimization of design and layout of difficult airway trolleys (DATs) may influence outcomes during airway emergencies. The main objective of the current study was to evaluate whether a difficult airway algorithm-based DAT with integrated cognitive aids improves efficiency and team performance in difficult airway scenarios. ⋯ Algorithm-based DATs with integrated cognitive aids may improve efficiency in difficult airway situations, compared to traditional DATs. These findings have implications for improvement of anesthetic practice.

Use of vasoactive agents in non-cardiac surgery: protocol for a scoping review.
An increasing number of patients undergo surgical procedures worldwide each year, and despite advances in quality and care, morbidity and mortality rates remain high. Perioperative hypotension is a well-described condition, and is associated with adverse outcomes. Both fluids and vasoactive agents are commonly used to treat hypotension, however, whether one vasoactive agent is preferable over another has yet to be explored. ⋯ The outlined scoping review will provide a summary of the body of evidence on the use of vasoactive agents in the non-cardiac surgical population.

Randomized Controlled TrialSleep quality and quantity determined by polysomnography in mechanically ventilated critically ill patients randomized to dexmedetomidine or placebo.
Abnormal sleep is commonly observed in the ICU and is associated with delirium and increased mortality. If sedation is necessary, it is often performed with gamma-aminobutyric acid agonists such as propofol or midazolam leading to an absence of restorative sleep. We aim to evaluate the effect of dexmedetomidine on sleep quality and quantity. ⋯ Total sleep time and sleep efficiency were significantly increased, without elimination of REM sleep, in mechanically ventilated ICU patients randomized to dexmedetomidine, when compared to a control PSG recording performed during non-sedation/standard care.

Randomized Controlled TrialSingle injection combined suprascapular and axillary nerve block. A randomised controlled non-inferiority trial in healthy volunteers.
A shoulder block without lung affection is desirable. In this study, we compared a low versus a high volume of a modified supraclavicular brachial plexus block. We hypothesised that a low volume of local anaesthetic would provide non-inferior block success rate with better preserved lung function. ⋯ For our primary outcome, the 95% CI of the difference of event ratio included the non-inferiority margin. We are therefore unable to conclude that 5 ml LA is non-inferior to 20 ml LA with respect to block success rate.

Randomized Controlled TrialPreparing for obstetric anaesthesia - an educational randomised controlled trial comparing e-learning to written course material.
E-learning is increasingly used in postgraduate medical education. Its numerous benefits include an enhanced learning experience through learning style individualisation, interactive elements, and assessment through tests and quizzes. Current meta-analyses conclude that the overall effectiveness of e-learning is comparable to traditional teaching modalities. However, studies demonstrating its benefits are heterogeneous and of varying quality. This randomised controlled trial aims to investigate whether contemporary e-learning completed prior to a course in obstetric anaesthesia prepares the course participants better than self-study of written course material. ⋯ This blinded parallel group randomised controlled trial found a numerically small but statistically significant difference in knowledge favouring e-learning over written course material.
