GENERAL ANESTHESIA AND SEDATION
What is sedation?
The patient is relaxed with the combination of some sedatives (Diazem like) and narcotic analgesics (morphine like), along with a hypnotic medicine on some occasions. A short period of amnesia (loss of memory) is induced and dental treatment is carried out rapidly under local anesthesia.
What is general anesthesia?
Known as Narcosis among people, General Anesthesia is induced with a combination of three medicines:
1 – Temporary loss of consciousness due to hypnotic medicines
2 – A painless operation due to narcotic analgesics (morphine like) even tough the patient is unconscious
3 – Muscle relaxants (Curare) relax all the muscles and provide a comfortable surgery. All the muscles including the respiratory ones are paralyzed temporarily with muscle relaxants. The respiration is maintained by a small sterile tube named “endotracheal tube” that is placed into the respiratory tract (trachea) along with an anesthesia device (respiratory device) under the surveillance of an anesthesiologist.
Continuity of the general anesthesia is maintained by the inhalation of oxygen/air or oxygen/air/nitrous oxide combination or with volatile agents.
