Anesthesia |
Art and science of providing anesthesia and analgesia Clinical use of pharmacology, physiology, and anatomy |
|
|
General anesthesia |
Reversable loss of sensation to whole body with unconsciousness, amnesia, muscle relaxation, and analgesia Can be injectable or inhalation |
|
|
Stage one of anesthesia |
voluntary movement lasts from beginning of drug administration to loss of consciousness |
|
|
Stage two of anesthesia |
Stage of involuntary movement and delirium lasts from loss of consciousness to regular breathing |
|
|
Stage three of anesthesia |
stage of surgical anesthesia characterized by unconsciousness, progressive depression of reflexes, muscle relaxation, slow, regular breathing Can be subdivided into three planes medium (progressive intercostal paralysis) deep (diaphragmatic breathing problem) |
|
|
Stage four of anesthesia |
excessive depth of anesthesia characterized by apnea, mydriosis, and profound hypotension death ensues without intervention |
|
|
Regional anesthesia |
Reversible loss of sensation to a portion of the body due to blockade of a large nerve or group of nerves epidural/spinal anesthesia or brachial plexus block |
|
|
Local anesthesia |
Reversible loss of sensation to a more limited area of the body due to blockade of a single nerve or group of nerves paraveterbral nerve block, cornual nerve block |
|
|
Surgical anesthesia |
Reversible loss of sensation of sufficient intensity to allow completion of surgical procedures
|
|
|
Dissociative anesthesia |
produced by drugs that dissociate the thalamocortic and limbic systems producing a cataleptoid state, usually with muscle rigidity
|
|
|
Balanced anesthesia |
Several drugs are used in combination to produce anesthesia
Each drug provides a component - unconsciousness, analgesia, and muscle relaxation premed + agent + supplemnt = 1 |
|
|
Tranquilization |
State of reduced awareness and relaxation but still aware of surroundings
no analgesia present |
|
|
Sedation |
State of CNS depression and reduced awareness of surroundings
Whether or not analgesia is present depends on drug and dose e.g. Acepromazine, alpha-2 agents |
|
|
Analgesia |
Absence of pain whether or not consciousness or sedation is present depends on drug and dose opiods and NSAIDS |
|
|
Narcosis |
Drug induced state of deep sleep from which animal may not be arousable |
