Systemic perturbations such as peripheral surgical trauma induce neurovascular, inflammatory, and cognitive changes. The blood-brain barrier is a key interface between the periphery and the central nervous system, and is critically involved in regulating neuroimmune interactions to maintain overall homeostasis. Mounting evidence suggests that blood-brain barrier dysfunction is a hallmark of ageing and multiple neurological conditions including Alzheimer's disease. We discuss a recent study published in the British Journal of Anaesthesia that describes blood-brain barrier changes and neuroinflammation in patients with postoperative delirium after non-intracranial surgery.

Tackling the climate emergency is now a key target for the healthcare sector. Avoiding inhalational anaesthesia is often cited as an important element of reducing anaesthesia-related emissions. However, evidence supporting this is based on adult practice. The aim of this study was to identify the difference in carbon footprint of inhalational and i.v. anaesthesia when used in children. ⋯ In a simulation study, i.v. anaesthesia had climate benefits in paediatric anaesthesia. However, when used after inhalational induction, benefits were only achieved in longer procedures. These findings provide evidence-based guidance for reducing the environmental impact of paediatric anaesthesia, but these will require confirmation using real-world data.

Observational Study
Reliability of the Minto model for target-controlled infusion of remifentanil during cardiac surgery with cardiopulmonary bypass.
The Minto pharmacokinetic model is used for target-controlled infusion of remifentanil. The reliability of this model has never been evaluated during normothermic cardiac surgery with cardiopulmonary bypass (CPB). The aim of this study was to assess the predictive performance of the model during CPB to determine its reliability during cardiac surgery. ⋯ 2017-A03153-50.
