Analgesia : it is state which has temporarily abolishes awareness
of pain
Narcosis: It sleep like action due to moderate depression of CNS,
thus all anesthetic agent are narcotic but not many narcotic are

and unconsciousness
Sedative : is a narcotic agent which is used to calm a nervous,
vicious or excited animals. `

General considerations in the selections of Anesthetic
1- Animals
2- Nature of operation
Inspection before anaesthesia
• Check animals before starting
• Do not anaesthetise sick
animals, they are unsuitable
• Animal should be fasting
How to fast before anaesthesia ?
• Take away food - not water
• the smaller species, the faster metabolism,
the shorter fasting

Blood
Brain
i.v., i.m, orally, per rectum,
intraperitoneal,
Elimination of inhalation anesthetics
