ReviewUpdate on the role of non-opioids for postoperative pain treatment.
Non-opioids play an ever increasing role in the treatment of postoperative pain; either on their own for mild to moderate pain or in combination with other analgesic approaches, in particular opioids, as a component of multimodal analgesia. The analgesics paracetamol (acetaminophen) and dipyrone (metamizole) as well as compounds with an additional anti-inflammatory effect (non-selective non-steroidal anti-inflammatory drugs and selective cyclo-oxygenase-2 inhibitors) are used widely in the perioperative period. ⋯ Dipyrone continues to be used in many countries despite the ongoing debate on the incidence and relevance of its ability to cause agranulocytosis. Among the anti-inflammatory drugs, selective cyclo-oxygenase-2 inhibitors have the most supportive data for their beneficial effects as a component of multimodal analgesia and offer benefits with regard to their adverse effect profile.

ReviewDo we need preemptive analgesia for the treatment of postoperative pain?
Preemptive analgesia means that an analgesic intervention is started before the noxious stimulus arises in order to block peripheral and central nociception. This afferent blockade of nociceptive impulses is maintained throughout the intra-operative and post-operative period. ⋯ So far, the promising results from animal models have not been translated into clinical practice. Therefore, clinicians should rely on conventional anaesthetic and analgesic methods with proven efficacy, i.e. a multimodal approach including the combination of strong opioids, non-opioid analgesics, and peripheral or neuraxial local anaesthetics that act at different sites of the pain pathways.

Intensive Care Medicine epitomises the difficulties inherent in modern medicine. In this chapter we examine some key medicolegal and ethical areas that are evolving. The principles of autonomy and consent are well established, but developments in UK caselaw have shown that the courts may be moving away from their traditional deference of the medical profession. We examine some recent cases and discuss the impact that these cases may have on practice in Intensive Care.

It is not possible to generalise about the way in which increasing years affect the performance of an individual anaesthetist. Physical and mental deterioration occurs as we age; most anaesthetists will be able to reach the normal retirement age of 65 years without that deterioration affecting their clinical practice. In some, however, decreasing competence and an unwillingness to embrace a continuing education regime may offer a direct threat to patient safety. ⋯ Continuing involvement in the on-call rota is a potent stressor. Airline pilots are required to retire at 60 years; the feasibility and desirability of applying this process to anaesthetists are discussed. Employers have a duty to provide employees with adequate and achievable demands in relation to their agreed hours of work and to have in place policies and procedures to offer adequate support.

This chapter discusses a framework for and process of ethical decision making in the context of the discipline, theories, and principles of ethics. Daily decision making within the Hospital Ethics Committee is considered and some of the emerging ethical issues in anaesthesia are discussed.
