Since then, a firm consensus has emerged in American law and ethics that 'Patients have a virtually unlimited right to refuse any unwanted medical treatment, even if necessary for life itself.' With regard to patients who are unable to make decisions for themselves, both Europe and the United States are converging toward a view that respects a role for surrogates in decision-making while recognizing the need to limit their authority. Beyond decisions to withdraw and withhold treatments, both the United States and Europe are experimenting with active hastening of the dying process through euthanasia and physician-assisted suicide. In the author's opinion, the next big question to be addressed in end-of-life decision-making is 'Just how bad does the neurological condition and prognosis need to be before it is acceptable to allow a decision to withdraw life support'? Although the practices described here have wide acceptance throughout the United States and Europe, the worldwide emergence of religious fundamentalism and the associated vitalistic view about the sanctity of life may result in significant changes over the next few decades.</p>","PeriodicalId":11873,"journal":{"name":"European journal of anaesthesiology.

Neurologic complications, such as sepsis‐associated encephalopathy, frequently occur in septic patients and are associated with higher mortality and long‐term complications. As case fatalities and overall mortality continue to decline, long‐term cognitive problems are becoming more common among survivors. Although the aetiology of septic encephalopathy has not been clearly established, systemic inflammation appears to play a key role in altering both the blood‐brain barrier permeability and amplifying the inflammatory response. Several new therapies are now aimed at reducing systemic inflammation. These may eventually play a role in reducing neurologic complications related to the acute pathophysiology of sepsis and may be able to reduce early cerebral dysfunction with the goal of reducing long‐term neurologic complications. Coupled plasma filtration adsorption is an extracorporeal therapy aimed at the non‐specific removal of cytokines and mediators involved in systemic inflammation and immune suppression by the use of plasma filtration coupled to an adsorbent resin cartridge with high affinity for many cytokines and mediators. Several cytokines that are removed by coupled plasma filtration adsorption have also been implicated in blood‐brain barrier permeability, leucocyte recruitment and amplification of the inflammatory response. Current studies are ongoing to determine whether treatments such as coupled plasma filtration adsorption may also be beneficial in reducing long‐term neurologic complications.","PeriodicalId":11873,"journal":{"name":"European journal of anaesthesiology.

Unfortunately, in-depth clinical assessment of the neuromuscular respiratory system is difficult with critically ill patients, and electrophysiological studies have been used instead to overcome this problem. Of these latter, electric and electromagnetic stimulation of the phrenic nerve have been successful (along with needle electromyography of the diaphragm) in identifying the causes of neuromuscular respiratory insufficiency, especially in Intensive Care.

Since 1984, cases of critical illness polyneuropathy have been reported from several countries. Moreover, a number of investigators reported instances of critical illness myopathy.

Many papers highlight the knowledge, skills and expertise required by nurses for the conduct of trials. The known skills include reliability, organization, communication, motivation, self-discipline and critical thought. The responsibilities of nurses in the conduction of research trials are wide ranging from the collection and recording of data, recruitment and screening of patients, ensuring informed consent has been gained, randomization of drugs, the follow-up of patients to development and training for staff to the required international standards. In the past, clinical research nurses have been considered as data collectors by their peers, due to the lack of knowledge of the true extent of the role of the clinical research nurse. The rise in popularity of the role and the publication of an employment brief for clinical research nurses by the Royal College of Nursing (RCN) and the UK Clinical Research Collaboration (UKCRC) publication on 'Developing the best research professionals' has readdressed this prior imbalance; recognizing in detail their role, knowledge, skills, expertise with appropriate grading and remuneration. The role of the clinical research nurse in the neuroscience setting is equally as diverse with the added requirement of a higher level of knowledge and understanding of the pathophysiology of neurological diseases and specific skills required to work in the intensive care environment.
