The timely correction of anaemia before major surgery is important for optimising perioperative patient outcomes. However, multiple barriers have precluded the global expansion of preoperative anaemia treatment programmes, including misconceptions about the true cost/benefit ratio for patient care and health system economics. ⋯ In some health systems, billing for iron infusions could generate revenue and promote growth of treatment programmes. The aim of this work is to galvanise integrated health systems worldwide to diagnose and treat anaemia before major surgery.

The analysis of arterial pressure waveforms with machine learning algorithms has been proposed to predict intraoperative hypotension. The ability to forecast arterial hypotension 5-15 min ahead of the fall in blood pressure allows clinicians to be pro-active instead of reactive, and could potentially decrease postoperative morbidity. ⋯ Continuous blood pressure monitoring enables immediate detection of hypotension, and giving fluid, vasopressors or inotropes to patients who are not yet (and might never become) hypotensive based on an algorithm is questionable. Finally, recent prospective interventional studies suggest that reducing intraoperative hypotension does not improve postoperative outcomes.

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.
