ReviewArterial waveform analysis in anesthesia and critical care.
In this review, we describe the basic principles of arterial waveform analysis (AWA) to assess cardiac output (CO) and cardiac preload. The validity of commercially based hemodynamic monitoring systems is discussed, together with their clinical applications and limitations. ⋯ AWA provides a less invasive and easy-to-use alternative for CO measurement. The validity of AWA devices has been verified in a variety of patients and circumstances, but their performance is compromised in the presence of hemodynamic instability, cardiac arrhythmias, or other factors disturbing the arterial pressure waveform. The definitive role of dynamic preload parameters like SVV and PPV is a matter of research. Large trials in which the value of early goal-directed therapy using this technology is studied in relation to outcome are urgently needed.

This review intends to give an overview of developments in anaesthesia residency training. ⋯ Innovations in the field of educational studies have provided us with tools to improve the training of our residents. Portfolio, simulation and quality assurance are among the most prominent developments aimed at creating successful residency programmes. Financial implications of the implementation of educational innovations should, however, be considered.

This article will provide a review of mentorship in academic medicine. The review will include definitions and an overview of the evidence supporting the benefits, barriers, and structure of mentorship programmes in academic medicine and anesthesia. Finally, we will identify areas of further research. ⋯ Mentorship has been demonstrated to be an integral part of training and career development in academic medicine and benefits both mentees and mentors. Despite the promotion of mentorship in many academic anesthesia departments, little is published in the available literature supporting mentorship in anesthesia.

This review is aimed at highlighting the recent developments and opportunities that are likely to impact the anesthesia team of the future. ⋯ The anesthesia team of the future will require the anesthesiologist to provide expertise across the entire domain of perioperative medicine. Meaningful decision support systems rely on accurate data analysis and incorporation of current clinical guidelines and recommendations.

Delirium is an acute, potentially life-threatening organ dysfunction with an incidence reported to range from 10-70% after surgery. Postoperative delirium was found to be associated with persisting cognitive deficits, increased physical dependence and institutionalization, and increased mortality. It is a condition particularly relevant to patients with increasing age. ⋯ Delirium may have an impact on patients' outcomes beyond their stay in hospital, depending on preoperative comorbidities. Delirium can be devastating for activity of daily living, cognitive performance and survival. Predisposing factors should be recognized preoperatively; precipitating factors such as preoperative fasting, deep sedation and choice of psychotropic drugs, including sedatives, should be reconsidered. Regular structured delirium screening is the precondition for early detection and treatment. Treatment options include cognitive training programmes, anti-inflammatory measures and antipsychotic drugs.
