To induce general anesthesia, propofol is the drug used almost exclusively, having largely replaced sodium thiopental. [13]It is often administered as part of an anesthesia maintenance technique called total intravenous anesthesia, using either manually programmed infusion pumps or computer-controlled infusion pumps in a process called target controlled infusion (TCI).
Twilight anesthesia is an anesthetic technique where a mild dose of sedation is applied to induce anxiolysis (anxiety relief), hypnosis, and anterograde amnesia (inability to form new memories). The patient is not unconscious, but sedated.
Total intravenous anesthesia (TIVA) refers to the intravenous administration of anesthetic agents to induce a temporary loss of sensation or awareness. The first study of TIVA was done in 1872 using chloral hydrate , [ 1 ] and the common anesthetic agent propofol was licensed in 1986.
Called target controlled infusion (TCI), it involves using a computer-controlled syringe driver (pump) to infuse propofol throughout the duration of surgery, removing the need for a volatile anaesthetic and allowing pharmacologic principles to more precisely guide the amount of the drug used by setting the desired drug concentration.
General anesthesia drugs such as midazolam, ketamine, propofol and fentanyl are used to put a person in a twilight state or render them completely unconscious and unaware of pain. Dentists who have completed a training program in anesthesiology may also administer general IV and inhalation anesthetic agents.

General anesthetics that agonize them are typically used to induce a state of sedation and/or unconsciousness. Such drugs include propofol, etomidate, isoflurane, benzodiazepines (midazolam, lorazepam, diazepam), and barbiturates (sodium thiopental, methohexital). [2] [3] [4]
