The past two decades have seen an increasing recognition that the delivery of safe surgery with low complication rates and good long-term outcomes is a team endeavour embracing the whole patient care pathway. The key role of the anaesthetist in managing the patient through the surgical process is widely understood and has driven the emergence of perioperative medicine. In parallel with these developments there has been a sea change in the organisation of the care of patients presenting for elective abdominal aortic aneurysm (AAA) repair. ⋯ These changes paralleled and in some cases led the wider evolution of the role of the anaesthetist in perioperative medicine. The mortality from infrarenal AAA repair in the UK decreased to 2.4% by 2012. This improvement reflects changes in perioperative care supported and in some cases led by anaesthetists.

In an era when healthcare has become increasingly complex and patient expectations are higher than ever before, we can find the decision-making process for patients, potentially at the end of their lives, increasingly difficult. In the shift from paternalism to patient choice, we can struggle to know what to do when faced with a patient, their family, or both requesting or demanding inadvisable, inappropriate, or futile treatments. It can feel as if we are being asked to subject patients to intrusions and interventions that 'just feel wrong'. In this article, we aim to look at how ethical frameworks, legal statute, case law, and professional guidance, as they apply in the UK, interact when we make these decisions, and we discuss some of the conflicts and challenges that such guidance pose.

Approximately 12% of apparently previously cognitively well patients undergoing anaesthesia and noncardiac surgery will develop symptoms of cognitive dysfunction after their procedure. Recent articles in this Journal have highlighted the difficulties of confirming any clear links between anaesthesia and cognitive dysfunction, in part because of the lack of consistency regarding definition and diagnosis. Postoperative cognitive dysfunction (POCD) is usually self-limiting and rarely persists in the longer term, although plausible biological mechanisms for an impact on brain protein deposition do exist. ⋯ As yet no individual anaesthetic technique, drug or mode of monitoring has been proved to reduce the incidence of POCD. Providing patients with appropriate and accurate information can be difficult because of conflicting evidence. The Royal College of Anaesthetists' patient liaison group has produced a useful patient information leaflet that is designed to provide guidance in discussions of individual risks whilst considerable uncertainties remain.

Human beings who work in complex, dynamic, and stressful situations make mistakes. This is as true for anaesthetists as for any other health-care professional, but we face unique challenges in the many roles and responsibilities we have in diverse clinical contexts. ⋯ This review considers the impact of error in health care; the role of anaesthetists in promoting simulation-based education for the development of clinical skills and improved teamwork; and their role in disseminating human factors and quality improvement science to enhance safety in the clinical workplace. Finally, we consider our position at the vanguard of developments in patient safety and how the profession should continue to pursue a leadership role in the application of simulation-based interventions to training and systems design across health care.

Comparative Study
Effectiveness of enhanced pulse oximetry sonifications for conveying oxygen saturation ranges: a laboratory comparison of five auditory displays.
Anaesthetists monitor auditory information about a patient's vital signs in an environment that can be noisy and while performing other cognitively demanding tasks. It can be difficult to identify oxygen saturation (SpO2) values using existing pulse oximeter auditory displays (sonifications). ⋯ Enhanced sonifications are more informative than conventional sonification. The implication is that they might allow anaesthetists to judge better when desaturation decreases below, or returns to, a target range.
