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.

Observational StudyThe optimum time for intravenous cannulation after induction with Sevoflurane in children premedicated with Dexmedetomidine.
Inhalation anesthesia is a frequently used method for anesthesia induction, especially in young children. No information is available on the optimum time for safe intravenous cannulation after inhalational induction in children with dexmedetomidine premedication. The purpose of the present study was to determine the optimal time for intravenous cannulation after induction of anesthesia with sevoflurane and nitrous oxide in children premedicated with intranasal dexmedetomidine. ⋯ In conclusion, we suggest that the appropriate time for cannulation is 85 s (1.45 min) after the loss of eyelash reflex in children sedated with dexmedetomidine and induction with sevoflurane and nitrous oxide-oxygen mixture.

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.

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.
