General anaesthetics (or anesthetics) are often defined as compounds that induce a loss of consciousness in humans or loss of righting reflex in animals. Clinical definitions are also extended to include an induced coma that causes lack of awareness to painful stimuli, sufficient to facilitate surgical applications in clinical and veterinary practice.
The first drug used for this purpose was curare, introduced in the 1940s, which has now been superseded by drugs with fewer side effects and, generally, shorter duration of action. [42] Muscle relaxation allows surgery within major body cavities , such as the abdomen and thorax , without the need for very deep anaesthesia, and also facilitates ...
Its binding site is located in the transmembrane section of this receptor between the beta and alpha subunits (β + α −). β3-containing GABA A receptors are involved in the anesthetic actions of etomidate, while the β2-containing receptors are involved in some of the sedation and other actions that can be elicited by this drug.
Infants differ from adults in the consideration of pharmacokinetics, pharmacodynamics and side effects. [57] In terms of pharmacokinetics, protein binding, organ function and body composition are significantly different. [58] Pharmacodynamic effects such as the capacity of target organs to respond to drugs are also changed. [57]
NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. [1] Ketamine is a favored anesthetic for emergency patients with unknown medical history and in the treatment of burn victims because it depresses breathing and circulation less than other anesthetics.
Structures of general anaesthetics widely used in medicine. [1] 1 - ethanol, 2 - chloroform, 3 - diethyl ether, 4 - fluroxene, 5 - halothane, 6 - methoxyflurane, 7 - enflurane, 8 - isoflurane, 9 - desflurane, 10 - sevoflurane. A general anaesthetic (or anesthetic) is a drug that brings about a reversible loss of consciousness. [2]
Etomidate is an imidazole derivative, commonly used for the induction of general anesthesia. Effects kick in almost immediately, within 5–15 seconds, and last 5–15 minutes. [3] Etomidate carries sedative effects only; it does not provide pain relief. Side effects of etomidate include myoclonus (involuntary muscle jerking) and respiratory ...
An inhalational anesthetic is a chemical compound possessing general anesthetic properties that is delivered via inhalation. They are administered through a face mask, laryngeal mask airway or tracheal tube connected to an anesthetic vaporiser and an anesthetic delivery system .
