Palliative sedation: In medicine, specifically in end-of-life care, palliative sedation (also known as terminal sedation, continuous deep sedation, or sedation for intractable distress in the dying/of a dying patient) is the palliative practice of relieving distress in a terminally ill person in the last hours or days of a dying patient's life, usually by means of a continuous intravenous or subcutaneous infusion of a sedative drug, or by means of a specialized catheter designed to provide comfortable and discreet administration of ongoing medications via the rectal route. Palliative sedation is an option of last resort for patients whose symptoms cannot be controlled by any other means.Procedural sedation and analgesia: Procedural sedation and analgesia, previously referred to as conscious sedation, is defined as "a technique of administering sedatives or dissociative agents with or without analgesics to induce a state that allows the patient to tolerate unpleasant procedures while maintaining cardiorespiratory function."Nonbenzodiazepine: Nonbenzodiazepines (sometimes referred to colloquially as "Z-drugs") are a class of psychoactive drugs that are very benzodiazepine-like in nature. Nonbenzodiazepines pharmacodynamics are almost entirely the same as benzodiazepine drugs and therefore employ similar benefits, side-effects, and risks.Propofol infusion syndrome: Propofol infusion syndrome (PRIS) is a rare syndrome which affects patients undergoing long-term treatment with high doses of the anaesthetic and sedative drug propofol. It can lead to cardiac failure, rhabdomyolysis, metabolic acidosis, and kidney failure, and is often fatal.MidazolamInternational Federation of Dental Anesthesiology Societies: The International Federation of Dental Anesthesiology Societies (IFDAS) is a professional association established in 1976. IFDAS is devoted solely to promoting the safe and effective use of sedation and anesthesia by educationally qualified dentists for their patients.Cranio-corpography: Cranio-Corpo-Graphy (CCG) is a medical investigation and measurement procedure developed in 1968 by German neurootologist Claus-Frenz Claussen. It documents and evaluates disorders of the equilibrium function measured by investigation procedures such as the Unterberger test, the LOLAVHESLIT test, the NEFERT test, the Romberg's test and the WOFEC test.Hydrate: In chemistry, a hydrate is a substance that contains water or its constituent elements. The chemical state of the water varies widely between different classes of hydrates, some of which were so labeled before their chemical structure was understood.Voluntary euthanasia: Voluntary euthanasia is the practice of ending a life in a painless manner. Voluntary euthanasia (VE) and physician-assisted suicide (PAS) have been the focus of great controversy in recent years.EPESociety for Old Age Rational Suicide: The Society for Old Age Rational Suicide (SOARS) is a group based in the United Kingdom concerned with choice at the end of life. It was established on December 10, 2009 (Human Rights Day) by Dr.General anaesthesia: General anaesthesia (or general anesthesia) is a medically induced coma and loss of protective reflexes resulting from the administration of one or more general anaesthetic agents. A variety of medications may be administered, with the overall aim of ensuring unconsciousness, amnesia, analgesia, relaxation of skeletal muscles, and loss of control of reflexes of the autonomic nervous system.OhmefentanylLanicemine: Lanicemine (AZD6765) is a low-trapping NMDA receptor antagonist developed by AstraZeneca, which was being studied for the management of severe and treatment-resistant depression. It was originally developed as a neuroprotective agent, but was redeveloped as an antidepressant following the observation that the NMDA receptor antagonist ketamine has potent antidepressant effects, but also has hallucinogenic side effects which make it unsuitable for use as an antidepressant in most circumstances.Meridian of Antwerp: The meridan of Antwerp is one of several prime meridians that have been used for geographic referencing. It is running through the city of Antwerp, in Flanders, Belgium, and forming the 0° longitude upon which some Belgian maps were based.
