Randomized Controlled Trial
Does warm-up using mental practice improve crisis resource management performance? A simulation study.
Mental practice (MP) is defined as the 'symbolic rehearsal of a physical activity in the absence of any gross-muscular movements' and has been used in sport and music to enhance performance. In healthcare, MP has been demonstrated to improve technical skill performance of surgical residents. However, its effect on crisis resource management (CRM) skills has yet to be determined. We aimed to investigate the effect of warm-up with MP on CRM skill performance during a simulated crisis scenario. ⋯ Unlike technical skills, warm-up with MP does not seem to improve CRM skills in simulated crisis scenarios.

Randomized Controlled Trial Comparative Study
Ultrasound visual image-guided vs Doppler auditory-assisted radial artery cannulation in infants and small children by non-expert anaesthesiologists: a randomized prospective study.
Cannulation of the radial artery in infants and small children can be challenging, even for the most experienced providers. Utilizing Doppler to aid in radial artery cannulation has been well described. Recent studies have demonstrated the efficacy of ultrasound (US) image-guided vascular access techniques in the paediatric population. The utility of these two techniques, when used by non-expert personnel, has not been studied. ⋯ US-guided radial arterial cannulation in infants and small children provided a greater chance for success at the first attempt compared with the Doppler-assisted technique.
