GENERAL ANESTHESIA
,Definition
• General anesthesia is a reversible condition of CNS depression
which eliminates All sensations of the body accompanied by
anesthetic drugs.
Hallmarks of general anesthesia:
• Amnesia / unconsciousness
• Analgesia
• Muscle relaxation
, Phases Of General Anesthesia:
• Induction:
Begins with the onset of administration of general
anesthesia to the development of surgical anesthesia.
Preoxygenation, Induction, Muscle relaxants, Mask
ventilation, Intubation and ETT position confirmation are
the steps to be followed.
, • Maintenance:
Sustaining the state of general anesthesia. Usually done with an
admixture of Nitrous oxide and halogenated hydrocarbon
• Recovery:
At the end of surgical procedure, administration of anesthetic
agents is stopped and consciousness regains.
