Analgesia=
sensory block- failure of brain to receive impulses initiated by sensory stimuli
Amnesia=
Mental block- failure of arriving sensory impulse to pass on into memory storage
Reflex block=
failure of arriving sensory impulses to evoke a response.
Sedation=
slight depression, patient is awake
hypnosis
greater depression than sedation, patient asleep but can be wakened
narcosis
patient asleep, can be wakened, returns to sleep- usu good analgesia
tranquilization
some sedation and hypnosis, mainly alters behavir, reaction. Little or no alalgesia.
Analgesia
alleviation of pain
anesthesia
without sensation, pt asleep, cant be wakened. Amnesia and loss of reflexes
Analgesia=

Determination of anesthetic protocol
A. Species and breed
B. Age
C. Preaneshetic condition
D. Nature of operation
E. Equipment available

4 components of anesthetic period
preanesthesia- hx, pe, pab, drugs
induction- unconsciousness, some loss of reflexes(swallow)-onset of analgesia
maintenance- further reflex loss, mild resp and card depression
recovery- when anesthesia concentration in brain decreases- return of reflexes
Planes of anesthesia
I. Immed after drug given. Conscious, disoriented. RR, HR normal. All reflexes +
II. Loss of consciousness, reflexes +.Pupils dilated, constrict w/ light. May "fight" anesthesia
II. 1. Movement stops, eyeballs rotate ventrally, pupils partly constrict, < PLR. Endo tube can be put in.Reacts to pain.
III. 2. Surgical plane PLR sluggish, eyes central or rotated, pupils slightly dilated. RR shallow, 12-16 (dog)HR, BP < Loss of palpebral, pedal reflexes
III. 3.Too deep. Resp and Circ depression <12 breaths per minute. CRT 1.5-2 sec. Jaw tone slack
III. 4. Rocking boat
IV Respiratory emergency followed by cardiac-death.
