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).
They use simple tools to access the sap, which averages 3.1% ABV. This behavior suggests that ethanol does not deter feeding and indicates that the last common ancestor of African apes and humans likely consumed foods containing ethanol. [6] Chimpanzees at Bossou consumed large amounts of ethanol and showed signs of intoxication.
Most propofol is conjugated in the liver with pharmacologically inactive metabolites. [33] Although it has a long terminal elimination half-life of 4 to 30 hours, plasma concentrations remain low after the typical induction dose. [33]
Sodium thiopental is an ultra-short-acting barbiturate and has been used commonly in the induction phase of general anesthesia.Its use has been largely replaced with that of propofol, but may retain some popularity as an induction agent for rapid-sequence induction and intubation, such as in obstetrics.

The United States Environmental Protection Agency defines NOAEL as 'an exposure level at which there are no statistically or biologically significant increases in the frequency or severity of adverse effects between the exposed population and its appropriate control; some effects may be produced at this level, but they are not considered as adverse, or as precursors to adverse effects.

Concern regarding the safety of anaesthesia is especially acute with regard to children and infants, where preclinical evidence from relevant animal models suggest that common clinically important agents, including sevoflurane, may be neurotoxic to the developing brain, and so cause neurobehavioural abnormalities in the long term; two large ...
The onset of a myotoxic episode can occur within a few hours to a few days after local anaesthetic (LA) administration. A greater concentration and longer exposure to LA have been found to have a positive correlation with myotoxic effects. It can take human muscles from 4 days to a year to recover from a myotoxic insult.
