Anesthesia Terms & Jargon

Front 1

conduction

Back 1

injecting anesthetics arond nerves supplying the specific site; can be perineural (nerve block) or into the epidural or subarachnoid space (spinal)

Front 2

akinesia

Back 2

loss of motor response (movement) due to paralysis of motor nerves

Front 3

regional anesthesia

Back 3

generally suggests conduction anesthesia

Front 4

general anesthesia

Back 4

loss of consciousness & loss of sensation; ideally includes hypnosis, hyporeflexia, analgesia & muscle relaxation

Front 5

surgical anesthesia

Back 5

loss of consciousness & sensation with sufficient muscle relaxation & analgesia to allow surgery to be performed without pain or movement of the patient

Front 6

balanced anesthesia

Back 6

surgical anesthesia produced by a combination of two or more drugs or anesthetic techniques, each contributing its own pharmacologic effects
agents used: tranquilizers, narcotics, nitrous oxide and muscle relaxants

Front 7

dissociative anesthesia

Back 7

a central nervous system state characterized by catalepsy, profound peripheral analgesia, and altered consciousness produced by the cyclohexamine drugs

Front 8

catalepsy

Back 8

a state in which there is malleable rigidity of the limbs; the patient is generally unresponsive to aural, visual, or minor painful stimuli

Front 9

analgesia

Back 9

loss of sensitivity to pain

Front 10

intravascular anesthesia

Back 10

anesthetic solution is administered by intravenous, intra-arterial, intracardiac, or intramedullary injection

Front 11

local anesthesia

Back 11

anesthetic drugs applied topically, injected locally into or around the surgical site (field or regional block)

Front 12

hypnosis

Back 12

artificially induced sleep or a trance resembling sleep from which the patient can be aroused by stimuli

Front 13

narcosis

Back 13

drug-induced stupor or sedation in which the patient is oblivious to pain, with or without hypnosis

Front 14

neuroleptanalgesia

Back 14

hypnosis & analgesia produced by a combination of a neuroleptic drug and an analgesic drug

Front 15

sedation

Back 15

a mild degree of central depression in which the patient is awake but calm; a term often used interchangeably with tranquilization. With sufficient stimuli, the patient may be aroused. Sedatives act by a dose-dependent depression of the cerebral cortex

Front 16

tranquilization, ataraxia, neurolepsis

Back 16

a state of tranquility & calmness in which the patient is relaxed, awake & unconcerned with surroundings & potentially indifferent to minor pain. sufficient stimuli will arouse the patient.

Front 17

tranquilizers

Back 17

act by depressing the hypothalamus & the reticular activating system

Front 18

bag (2)

Back 18

1) a small plastic bag over the horse's muzzle during the physical examination, which results in the rebreathing of exhaled gas & deep breathing
2) the rebreathing bag on the anesthetic machine is squeezed to inflate the horse's lungs during anesthesia

Front 19

block

Back 19

used to describe the procedure of producing local anesthesia at a specific site such as a local nerve "block" or regional nerve "block"

Front 20

bolus

Back 20

implies that a specified quantity of drug was rapidly administered IV

Front 21

breathed

Back 21

used to relate that the animal's lungs were either manually or mechanically inflated

Front 22

crashed

Back 22

denotes the rapid induction of anesthesia generally by intravenous techniques, although increased concentrations of inhalation anesthetics have also been used for this purpose

Front 23

deep

Back 23

used to imply the degree of CNs depression produced by anesthetics. the greater the degree of CNS depression, the deeper the anesthesia

Front 24

light

Back 24

implies minimal CNS depression; light horses demonstrate active corneal & palpebral reflexes, may develop nystagmus, and occasionally lift their head or move a limb

Front 25

down

Back 25

implies that the animal was administered a drug or combination of drugs that produced recumbency

Front 26

dropped

Back 26

signifies that the horse has been administered drugs that produce recumbency

Front 27

extubate

Back 27

the endotracheal tube has been removed from the airway

Front 28

intubate

Back 28

placement of an endotracheal tube through the nose or mouth & into the trachea

Front 29

hit or stick a vein

Back 29

to perform a venipuncture successfully

Front 30

induced

Back 30

indicates the animal has been administered a drug or drugs that have produced anesthesia

Front 31

mask induction

Back 31

implies that a face mask was used to produce anesthesia. because face masks are used to supply gaseous or volatile anesthetics, the term also implies that an inhalation anesthetic is used

Front 32

pre- or post-

Back 32

terms used relative to the period of anesthesia.

Front 33

push

Back 33

implies that an IV drug or fluids are administered either rapidly or in amounts greater than are usually given

Front 34

ran a strip

Back 34

usually indicates that an electrocardiogram was obtained. generally the base-apex lead is used

Front 35

reversed

Back 35

indicates that drug effects were antagonized by administering a specific antagonist

Front 36

spiked

Back 36

1) may mean a sudden rapid increase
2) may mean that some substance (K+) or drug is added to a solution

Front 37

stabilized

Back 37

indicates that cardiopulmonary variables or the depth of anesthesia has been returned to or is within acceptable limits

Front 38

topped off

Back 38

indicates that additional drug has been administered to produce the desired effect; the term implies that the original calculated dosage was insufficient to produce the desired effect

Front 39

tubed

Back 39

indicates that an endotracheal tube was placed in the trachea by advancing the tube through either the mouth or nasal cavities
