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
Benzocaine is a local anesthetic. If it enters the esophagus, it can have an anesthetic effect of the airways, increasing the risk of inhalation of saliva.
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
The most common anaesthetic gases I see used are Sevoflurane and Desflurane.
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
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.
enflurane
The options include oral medication to help with anxiety, an injectable anesthetic to numb the area (and a good bit of your face), nitrous oxide (Inhalation Sedation) to alleviate pain, or general anesthesia in which you are completely knocked out for the procedure. Not all dentists offer all options. Many of the options can be used in concert with one another (oral medication, nitrous and injected anesthetic, for example). The available options depend on what your dentist offers and what the two of you decide is the best plan for you.
No, but excessive inhalation exposure may cause irritation to the upper respiratory tract (nose and throat) and lungs. Anesthetic or narcotic effects, dizziness and drowsiness are also possible.
