Observational Study
Perioperative EEG background and discharge abnormalities in children undergoing cardiac surgery: a prospective single-centre observational study.
We analysed the characteristics of abnormal electroencephalogram (EEG) patterns before, during, and 48 h after cardiac surgery in patients with heterogeneous congenital heart disease to assess their relationship to demographic and perioperative variables and to early patient outcomes. ⋯ Perioperative EEG abnormalities occurred frequently and correlated with numerous demographic and perioperative variables and adversely correlated with postoperative EEG abnormalities and early outcomes. The relation of EEG background and discharge abnormalities with long-term neurodevelopmental outcomes remains to be explored.

Editorial Comment
Volatile versus intravenous anaesthesia and perioperative neurocognitive disorders: anything to see here?
There is a potential differential effect of sevoflurane compared with propofol on postoperative delirium and other perioperative neurocognitive disorders. More generally, there are perhaps differences between volatile and intravenous anaesthetic agents in their possible impact on perioperative neurocognitive disorders. Strengths and limitations of a recent study in this journal and its contribution to our understanding of the impact of anaesthetic technique on perioperative neurocognitive disorders are discussed.

Delirium is a common and disturbing postoperative complication that might be ameliorated by propofol-based anaesthesia. We therefore tested the primary hypothesis that there is less delirium after propofol-based than after sevoflurane-based anaesthesia within 7 days of major cancer surgery. ⋯ Chinese Clinical Trial Registry (ChiCTR-IPR-15006209) and ClinicalTrials.gov (NCT02662257).

The British Journal of Anaesthesia (BJA) celebrates its centenary in 2023, and with it 100 yr of continuous anaesthesia research publication. As an editorially and financially independent journal, the BJA faced a rapidly changing anaesthesia profession, health system, and publishing world without the security of institutional support. In its early days, the Journal was vocal about the challenging conditions faced by anaesthetists before the National Health System was established, and was essential in advocating for the specialty. ⋯ As the Journal's fortunes began to improve, a new research and healthcare context emerged, radically changing the face of anaesthesia research and practice, to which the Journal needed to adapt. In spite of a range of challenges throughout the years, the BJA has developed into an international, future-focused, well-respected publication. This could not have been achieved without continual transformation, and the willingness to take risks and meet the changing times head on.

Clinical Trial
Pharmacodynamic mechanism-based interaction model for the haemodynamic effects of remifentanil and propofol in healthy volunteers.
Propofol and remifentanil are frequently combined for the induction and maintenance of general anaesthesia. Both propofol and remifentanil cause vasodilation and potentially reduce arterial BP. We aimed to develop a mechanism-based model that characterises the haemodynamic interactions between remifentanil and propofol. ⋯ NCT02043938; NCT03143972.
