Enflurane is less potent, but produces a rapid onset of anesthesia and possibly a faster recovery. Enflurane is not used in patients with kidney failure. Isoflurane is not toxic to the liver but can induce irregular heart rhythms
causes unconsciousness but provides little pain relief; often administered with analgesics . It may be toxic to the liver in adults. Halothane, however, has a pleasant smell and is therefore often the anesthetic of choice when mask induction is used
Sevoflurane is classified as a halogenated inhalation anesthetic and is considered to be relatively hydrophobic in nature.
The most common anaesthetic gases I see used are Sevoflurane and Desflurane.
now a days d most used common anesthetic is ethyl chloride
Anesthesia: Partial or complete loss of sensation, with or without loss of consciousness, as a result of disease, injury, or administration of an anesthetic agent, usually by injection or inhalation.
Local anesthetic is safe if the dosage is not excessive. When the area to aspirate is extensive, the high doses of local anesthetic required are toxic and may cause serious complications. In these cases, a general anesthetic (by inhalation) guarantees the best results, reducing risks to a minimum. In any case now the client can return home after the surgery.
halothane (a nonflammable inhalation anesthetic that produces general anesthesia; used along with analgesics and muscle relaxants for many types of surgical procedures)
suggests that anesthesia occurs when a sufficient number of molecules of an inhalation anesthetic dissolve in the lipid cell membrane
enflurane
irritating to the airway and therefore cannot be used for mask (inhalation) inductions, especially not in children. Desflurane causes an increase in heart rate, and so should be avoided for patients with heart problems
basal anesthesia narcosis produced by preliminary medication so that the inhalation of anesthetic necessary to produce surgical anesthesia is greatly reduced.
Chloroform is no longer used as a general anesthetic due to safety concerns. In the past, it was administered by inhalation to induce unconsciousness. However, chloroform can cause serious side effects, including respiratory failure and cardiac arrest, and its use has been largely replaced by safer alternatives.
