During surgery or other medical procedures, the patient is under what is known as a "twilight state", where the patient is relaxed and "sleepy", able to follow simple directions by the doctor, and is responsive. Generally, twilight anesthesia causes the patient to forget the surgery and the time right after.
Amnesia is desirable during surgery, so general anaesthesia procedures are designed to induce it for the duration of the operation. Sedatives such as benzodiazepines, which are commonly used for anxiety disorders, can reduce the encoding of new memories, particularly in high doses (for example, prior to surgery in order for a person not to recall the surgery).

Bromism is the syndrome which results from the long-term consumption of bromine, usually through bromine-based sedatives such as potassium bromide and lithium bromide. Bromism was once a very common disorder, being responsible for 5 to 10% of psychiatric hospital admissions, but is now uncommon since bromide was withdrawn from clinical use in ...
Leaves of the coca plant (Erythroxylum novogranatense var. Novogranatense), from which cocaine, a naturally occurring local anesthetic, is derived [1] [2]. An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia — in other words, to result in a temporary loss of sensation or awareness.
The colour fades at low temperatures so that solid bromine at −195 °C is pale yellow. [31] Liquid bromine is infrared-transparent. [36] Like solid chlorine and iodine, solid bromine crystallises in the orthorhombic crystal system, in a layered arrangement of Br 2 molecules. The Br–Br distance is 227 pm (close to the gaseous Br–Br ...
An example of this is a recognition test, where patients are asked to determine, after surgery, which of a selection of words could be heard during the surgery. The following scenario is an example. Patients were exposed during anesthesia to a list of words containing the word "pension".
Incapacitating agent is a chemical or biological agent which renders a person unable to harm themselves or others, regardless of consciousness. [1]Lethal agents are primarily intended to kill, but incapacitating agents can also kill if administered in a potent enough dose, or in certain scenarios.
During this stage, the patient's respiration and heart rate may become irregular. In addition, there may be uncontrolled movements, vomiting, suspension of breathing , and pupillary dilation . Because the combination of spastic movements, vomiting, and irregular respiration may compromise the patient's airway, rapidly acting drugs are used to ...
