Intravenous Anesthetics. Intravenous (i.v.) anesthetics include etomidate, midazolam, propofol, thiopental, ketamine, and opioid agonists. The first four agents act by enhancing the activity of the inhibitory neurotransmitter γ-aminobutyric acid (GABA) in the CNS.

What is ideal general Anaesthetic agent?

Sevoflurane Sevoflurane is closest to being the ideal agent, as it can be used for induction and for maintenance of anaesthesia. Its pleasant odour (pear drops), low blood solubility and low arrhythmogenic risk mean that it is becoming the agent of choice for gas induction.

Is propofol a local or general anesthesia?

Propofol is an intravenous anesthetic used for procedural sedation, during monitored anesthesia care, or as an induction agent for general anesthesia. It may be administered as a bolus or an infusion, or some combination of the two.

Is Propofol an induction agent?

Propofol is a rapidly acting intravenous anesthetic agent which has many advantageous kinetic properties explaining its usefulness by bolus dose for induction of anesthesia or for administration by continuous intravenous infusion.

Why is Pepcid given after surgery?

Pepcid or Tagamet – Take 2 (two) Pepcid AC or Tagamet HB (over the counter) in the morning and again in the evening. Taking these pills will reduce the flow of stomach acid and help prevent an upset stomach from medications given before and during surgery.

Is chloroform an anesthetic?

Chloroform and halothane are potent anaesthetic agents which are also chemically related. Halothane was introduced into clinical anaesthesia in 1956 at a time when anaesthesia had been fully developed. Chloroform was first used in 1847 by James Young Simpson when anaesthesia was in its infancy.

What is the most common anesthetic?

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 medications are used in general anesthesia?

Nearly all the medications commonly used for general anesthesia and sedation have the effect of lowering blood pressure and reducing sympathetic tone; some of them depress cardiac function as well. Common medications include propofol, fentanyl, midazolam, and the inhaled fluorinated ethers such as sevoflurane and desflurane.

What happens during general anesthesia?

General anesthesia works by interrupting nerve signals in your brain and body. It prevents your brain from processing pain and from remembering what happened during your surgery.

What are the four types of anesthesia?

There are four main categories of anesthesia used during surgery and other procedures: general anesthesia, regional anesthesia, sedation (sometimes called “monitored anesthesia care”), and local anesthesia. Sometimes patients may choose which type of anesthesia will be used.

What are the symptoms of too much anesthesia?

Patients and their families need to be aware of the common side effects of an anesthesia overdose prior to surgery so they can identify the symptoms. Here are some of the more common side effects that could indicate an anesthesia overdose: Nausea or vomiting. Respiratory distress. Hypothermia. Hallucinations. Seizures.
