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.
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).
General anaesthesia (UK) or general anesthesia (US) is medically induced loss of consciousness that renders a patient unarousable even by painful stimuli. [5] It is achieved through medications, which can be injected or inhaled, often with an analgesic and neuromuscular blocking agent .
[9] [10] These features can be desirable for endoscopic procedures such as esophagogastroduodenoscopy, colonoscopy, bronchoscopy, as well as for some surgical procedures done under local or regional anesthesia. Propofol is further metabolised to propofol glucuronide (34.8%) and quinol glucuronide. [11]
Propofol [6] is a non-barbiturate derivative that is thought to act by stimulating inhibitory GABA receptors and blocking excitatory NMDA receptors. It takes 40 seconds for the effects of propofol to kick in, and effects last six minutes. [3] Propofol has both sedative and amnestic effects, but provides no analgesia.

[1] [7] One survey of anesthesiologists who practice intravenous regional anesthesia found that 98% used adjuvant benzodiazepines and/or opioids, with benzodiazepines always being given systemically (to the whole body and brain), whereas opioids can be given either systemically or locally (only into the limb being anesthetized).
