Randomized Controlled Trial
Simulated patient-based teaching of medical students improves pre-anaesthetic assessment: A rater-blinded randomised controlled trial.
Pre-anaesthetic assessment of patients is a complex competency that needs to be taught during anaesthesia clerkships. ⋯ The current single teaching encounter with a trained layperson acting as a simulated patient improved medical student performances in their pre-anaesthetic clinical assessment of surgical patients. This might be a suitable alternative to reduce the teaching burden for busy and costly clinicians.

The impact of anaesthetic techniques on recurrence of cancers is controversial. Elevated plasma catecholamine levels have been implicated in angiogenesis and metastasis in various cancers. ⋯ Continuous administration of more than 2 μg kg BW h norepinephrine was associated with a slightly increased hazard ratio for tumour recurrence if adjusted for intra-operative variables and year of surgery. This observation could reflect a low potential pro-oncogenic effect of norepinephrine during the intra-operative period.

: Ultrasound for diagnostic and procedural purposes is becoming a standard in daily clinical practice including anaesthesiology and peri-operative medicine. The project of European Society of Anaesthesiology (ESA) Task Force for the development of clinical guidelines on the PERioperative uSE of Ultra-Sound (PERSEUS) project has focused on the use of ultrasound in two areas that account for the majority of procedures performed routinely in the operating room: vascular access and regional anaesthesia. Given the extensive literature available in these two areas, this paper will focus on the use of ultrasound-guidance for vascular access. ⋯ For other accesses, the evidence remains limited. For training in ultrasound guidance, there were no studies. The importance of proper training for achieving competency and full proficiency before performing any ultrasound-guided vascular procedure must be emphasised.
