Deep sedation – purposeful response to repeated or painful stimulation. General anesthesia – unarousable even with painful stimulus. In the United Kingdom, deep sedation is considered to be a part of the spectrum of general anesthesia , as opposed to conscious sedation.
This level, called deep sedation/analgesia, causes a drug-induced depression of consciousness during which the patient cannot be easily aroused, but responds purposefully following repeated or painful stimulation. Ventilatory functions may be impaired, so breathing tubes are required.
In medicine, specifically in end-of-life care, palliative sedation (also known as terminal sedation, continuous deep sedation, or sedation for intractable distress 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 person's life, usually by means of a continuous intravenous or subcutaneous infusion of a sedative ...
Deep sedation: You will likely be completely asleep for the entirety of the procedure thanks to propofol, a drug that is much less risky and easier to administer than general anesthetic.
Procedural sedation and analgesia (PSA) is a technique in which a sedating/dissociative medication is given, usually along with an analgesic medication, in order to perform non-surgical procedures on a patient. The overall goal is to induce a decreased level of consciousness while maintaining the patient's ability to breathe on their own.
Generally, full mechanical ventilation is only used if a very deep state of general anaesthesia is to be induced, and/or with a profoundly ill or injured patient. Induction of general anaesthesia usually results in apnea and requires ventilation until the drugs wear off and spontaneous breathing starts. In other words, ventilation may be needed ...
A sedative or tranquilliser [note 1] is a substance that induces sedation by reducing irritability [1] or excitement. [2] They are central nervous system (CNS) depressants and interact with brain activity causing its deceleration.
In his 2009 study, Macleod discussed how modern medical practices, such as the use of sedative medications, may contribute to the rarity of terminal lucidity. Deep sedation, which is often used to alleviate intractable symptoms, could deprive patients of the opportunity to experience moments of clarity and connection with loved ones before dying.
