What is an induction agent in Anaesthesia?
Induction agents are polyclonal lymphocyte-depleting antibodies (Thymoglobulin), monoclonal lymphocyte-depleting antibodies (alemtuzumab), or monoclonal nondepleting antibodies to IL-2R (basiliximab and daclizumab) that are given during the early peritransplantation period to decrease the risk of delayed graft function …
What drug puts you to sleep instantly surgery?
Propofol is used to put you to sleep and keep you asleep during general anesthesia for surgery or other medical procedures.
What is used before induction of anesthesia?
Induction of anesthesia should be achieved with an intravenous anesthetic agent of choice, usually propofol or thiopental, combined with an opiate and a nondepolarizing muscle relaxant.
How is anesthesia induced?
General anesthesia is commonly begun (induced) with intravenous (IV) anesthetics. But inhaled anesthetics also may be used. After you are unconscious, anesthesia may be maintained with an inhaled anesthetic alone, with a combination of intravenous anesthetics, or a combination of inhaled and intravenous anesthetics.
Why is propofol used for induction?
Propofol is the drug being used for day care surgeries because of its rapid, smooth induction and faster recovery. But its use is associated with pain on injection (even with added lidocaine), hypotension and respiratory depression.
Is propofol a general anesthetic?
Propofol is used as an “induction agent”—the drug that causes loss of consciousness— for general anesthesia in major surgery. In lower doses it is also used for “conscious sedation” of patients getting procedures on an outpatient basis at ambulatory surgery centers.
Why is lidocaine given for induction?
Induction of anaesthesia and its associated spikes in blood pressure can cause rupture of an aneurysm during intracranial surgery. Lidocaine can reportedly provide hemodynamic stability when applied before endotracheal intubation.
What is the 1 2 life of propofol?
Half-life: Propofol is bi-phasic, with its initial half-life being relatively quick, around 40 minutes, and its terminal half-life usually being 4 to 7 hours. Context-sensitive half-time may be up to 1 to 3 days after a 10-day infusion. The clinical effect of propofol is much shorter in duration.
What kind of medication is used to induce anesthesia?
There are various types of anesthesia, and most are given by inhalation (breathing in through the nose and mouth) or injection. The medication used to induce anesthesia is called an anesthetic.
What kind of drugs are used for preanesthetics?
Other preanesthetic drugs that depress the CNS, such as opioids, barbiturates, and antianxiety drugs, with or without antiemetic properties, may be contraindicated in the older individual. The preanesthetic drug is usually selected by the anesthesiologist and may consist of one or more drugs ( Table 17.2 ).
Can a local anesthetic be mixed with epinephrine?
The physician or dentist administers a local injectable anesthetic. These drugs may be mixed with epinephrine to cause local vasoconstriction. The drug stays in the tissue longer when epinephrine is used. This is contraindicated, however, when the local anesthetic is used on an extremity.
What are the different types of local anesthetics?
The various methods of administering a local anesthetic include topical application, local infiltration, and regional anesthesia. Topical anesthesia involves the application of the anesthetic to the surface of the skin, open area, or mucous membrane.
