Anaesthesia and sedation are ubiquitous in contemporary medical practice. Developments in anaesthetic pharmacology are targeted on reducing physiological disturbance whilst maintaining or improving titrateability, recovery profile and patient experience. Remimazolam is a new short-acting benzodiazepine in the final stages of clinical development. ⋯ Remimazolam provides effective procedural sedation with superior success rates and recovery profile when compared to midazolam. Comparisons with propofol are required. Preliminary studies suggest potential for using remimazolam as the hypnotic component of general anaesthesia. Definitive studies are awaited. As a benzodiazepine, remimazolam could be evaluated as an anticonvulsant and for intensive care sedation.

ReviewThe role of pharmacokinetics and pharmacodynamics in clinical anaesthesia practice.
Growing concerns about the environmental effects of volatile anaesthetics are likely to lead to increased use of intravenous anaesthetic drugs. Pharmacokinetic/pharmacodynamic (PKPD) models can increase the accuracy of intravenous drug titration, especially in populations that differ from the 'average.' However, with a growing number of PKPD models, and other technology available to date, it can be hard to see the wood for the trees. This review attempts to guide the reader through the PKPD jungle. ⋯ Newer and more complex modelling techniques and technological advancements can help to deliver anaesthetic drugs, sedatives and other drugs in a more stable and thereby safer way.

ReviewIntubation outside of the operating room: new challenges and opportunities in COVID-19 era.
Airway management in patients outside the operating room is associated with increased difficulties and risks, and the setting of the COVID-19 global pandemic adds another layer of complexity. Therefore, endotracheal intubation (ETT) of a patient who is presumptive COVID-19 or COVID-19 positive presents an additional challenge to an anesthesiologist. The aim of this review is to summarize the important principles of airway management outside of the operating room during the COVID-19 pandemic. ⋯ The COVID-19 pandemic redefined the management of patients requiring aerosol generating procedures (droplet and airborne precautions). ETT is one of them and anesthesiologists are experts in performing airway management. Although the operating room is a highly controlled environment, airway management outside of this setting is not always the easiest task.

ReviewNonoperating room anaesthesia: safety, monitoring, cognitive aids and severe acute respiratory syndrome coronavirus 2.
With an ageing population, mounting pressure on the healthcare dollar, significant advances in medical technology, and now in the context of coronavirus disease 2019, the traditional paradigm in which operative procedures are undertaken is changing. Increasingly, procedures are performed in more distant, isolated and less familiar locations, challenging anaesthesiologists and requiring well developed situational awareness. This review looks at implications for the practitioner and patient safety, outlining considerations and steps involved in translation of systems and processes well established in the operating room to more unfamiliar environments. ⋯ As NORA caseloads increase, understanding structural and anaesthetic requirements is essential to patient safety. The severe acute respiratory syndrome coronavirus 2 pandemic has provided an opportunity for anaesthesiologists to implement lessons learned from previous analyses, share expertise as patient safety leaders and provide valuable input into protecting patients and caregivers.

The present review aims to address the feasibility of opioid free anesthesia (OFA). The use of opioids to provide adequate perioperative pain management has been a central practice of anesthesia, and only recently has been challenged. Understanding the goals and challenges of OFA is essential as the approach to intraoperative analgesia and postsurgical management of pain has shifted in response to the opioid epidemic in the United States. ⋯ The feasibility of OFA is evident. However, there are limitations of this approach that warrant discussion including the potential for adverse drug interactions with multimodal analgesics, the need for providers trained in regional anesthesia, and the management of pain expectations. Additionally, minimizing opioid use perioperatively also requires a change in current prescribing practices. Monitors that can reliably quantify nociception would be helpful in the titration of these analgesics and enable anesthesiologists to achieve the goal in providing personalized perioperative medicine.
