What is the fastest acting anesthetic?

Sevoflurane is a sweet-smelling, nonflammable, highly fluorinated methyl isopropyl ether used as an inhalational anaesthetic for induction and maintenance of general anesthesia. After desflurane, it is the volatile anesthetic with the fastest onset .

What intravenous anesthetics has the rapid onset?

Propofol is the most widely used i.v. anesthetic agent for induction. It is highly lipophilic and distributes rapidly into the CNS and other tissues, which accounts for its rapid onset of action.

Is remifentanil an opioid?

Remifentanil is a novel member in the family of the 4-anilidopiperidine opioid analgesics which also include the traditional agents fentanyl, alfentanil, and sufentanil. Remifentanil undergoes widespread extrahepatic metabolism by blood and tissue nonspecific esterases, resulting in an extremely rapid clearance.

What drugs are used in general Anaesthetic?

Intravenous Agents: Propofol (Diprivan®), Ketamine, Etomidate. Propofol (Diprivan®) is the most commonly used IV general anesthetic. In lower doses, it induces sleep while allowing a patient to continue breathing on their own.

What drug induces anesthesia?

Propofol, etomidate, and ketamine are the intravenous (IV) sedative-hypnotic agents commonly used to induce general anesthesia (table 1).

What is the most common Anaesthetic?

Propofol (Diprivan®) is the most commonly used IV general anesthetic. In lower doses, it induces sleep while allowing a patient to continue breathing on their own. It is often utilized by anesthesiologist for sedation in addition to anxiolytics and analgesics.

What drug is used in Anaesthesia?

What are some examples of fast acting anesthetics?

If a drug is given by the IV route (intravenous), they enter the blood immediately, and are therefore the fastest. Common examples of such “fast acting” anesthetics are propofol, ketamine, etomidate, barbiturates, and benzodiazepines. Centrally acting Anesthetics drugs can also enter the blood through the lungs.

How do general anesthetics work?

What determines the speed of onset for local anesthetics?

On the subject of local anesthetics (not centrally acting anesthetics), speed of onset depends on many chemical and physical properties of the drugs, as well as what nerve is targeted by the drug. But I suspect you are interested in the above mentioned centrally acting agents.
