Randomized Controlled TrialEffect of statins on insulin requirements during non-cardiac surgery.
Statins are thought to potentially impair glucose metabolism, increasing plasma glucose concentration. The effect of prolonged statin use on glucose metabolism among outpatients is thus well established. However, the impact of statin use on glucose concentrations and insulin requirements during surgery remains poorly characterised and may very well differ considering the substantial hyperglycaemic stress response to surgery. ⋯ While the total amount of intraoperative insulin used was not statistically different between the statin users and non-users, we observed a potentially important trend toward insulin resistance intraoperatively among statin users during major non-cardiac surgery. This result is consistent with non-operative settings and cardiac surgery. Further investigation is essential to determine whether this effect is real and, if so, determine which specific statins are more associated with insulin resistance.

Comparative StudyMonitoring temperature in children undergoing anaesthesia: a comparison of methods.
Children undergoing anaesthesia are prone to hypothermia. Perioperative monitoring of patient temperature is, therefore, standard practice. Postoperative temperature is regarded as a key anaesthetic performance indicator in Australian hospitals. ⋯ Skin temperature showed a large variation from nasopharyngeal measurements. Our findings indicate that measured temperatures vary between sites. Understanding these variations is important for interpreting temperature readings.

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.
