Randomized Controlled Trial
Clinical decision-making augmented by simulation training: neural correlates demonstrated by functional imaging: a pilot study.
Investigation of the neuroanatomical basis of clinical decision-making, and whether this differs when students are trained via online training or simulation training, could provide valuable insight into the means by which simulation training might be beneficial. ⋯ The activation areas seen could indicate increased stress when answering clinical questions compared with general non-clinical questions, and in the online group when answering action-based clinical questions. These findings suggest simulation training attenuates neural responses related to stress when making clinical decisions.

Many preoperative fasting guidelines suggest that hot tea or coffee with milk added should be considered similar to solid food, allowing an interval of 6 h before commencing anaesthesia. There is little evidence to support these instructions, with recent guidelines undecided on the issue. This study aimed to establish whether there was a clinically significant delay in gastric emptying associated with adding a modest amount of milk to tea. ⋯ This study demonstrated no difference in gastric emptying times when a modest amount of milk was added to tea. These findings suggest that it may be acceptable to allow patients to add a small quantity of milk to their tea or coffee and follow the same fasting restrictions applied to clear fluids.
