Effect of magnetic resonance imaging on core body temperature in anaesthetised children.
Children undergoing magnetic resonance imaging (MRI) often require general anaesthesia (GA). Children under GA are at risk of decreases in body temperature. This risk may be greater during MRI due to MRI scanners requiring cool ambient temperatures. ⋯ The mean (± standard deviation) pre-scan temperature was 36.2°C±0.5°C, and the mean (± standard deviation) post-scan temperature was 35.9°C±0.6°C (an overall mean temperature decrease of 0.28°C was observed [95% confidence interval, -0.36°C to -0.19°C], P <0.001). In conclusion, core body temperature was found to decrease slightly during an MRI scan under GA. These results suggest that more focus is needed regarding the cooling effects of GA agents during MRI, as opposed to the heating effects of the MRI scanner.

Simulation has been advocated as a useful training tool, and specific manikin simulators have been developed for use in this role. Debriefing and repetition have been identified as key to achieving educational goals and, while the technical features of manikin simulators can influence simulation outcomes, their cost and infrastructure requirements reduce their suitability for smaller healthcare facilities. ⋯ This was effective in running high-fidelity, team-based in situ simulations and 'can't intubate, can't oxygenate' assessments for anaesthetic trainees. Though equipment in other centres may differ both in availability or suitability for simulation, the option we describe or similar may offer a low-cost solution for peripheral centres to run limited high-fidelity scenarios on a regular basis.
