|
define: Anesthesia
|
A total loss of sensation in a body part or in the whole body. Induced by a drug that depresses nervous tissue.
|
|
|
define: Local Anesthesia
|
Anesthesia limited to a local area.
|
|
|
define: General Anesthesia
|
Loss of consciousness in addition to loss of sensation. **Ideally includes: hypnosis, hyporeflexia, analgesia, and muscle relaxation.
|
|
|
define: Hypnosis
|
Artificially induced sleep or trance resembling sleep. Patient may be aroused w/ sufficient stimuli.
|
|
|
define: Hyporeflexia
|
A decreased responsiveness of normal muscle reflexes.
|
|
|
define: Analgesia
|
The loss of sensitivity to pain.
|
|
|
define: Sedation
|
A mild degree of central depression in which the patient is conscious, but calm. Often used interchangeably w/ Tranquilization. Sufficient stimuli will arouse the patient.
|

|
5 Major Potential Uses for Anesthesia/Sedation
|
1. Restraint
2. Surgery 3. Control of Seizures 4. Behavior Modification 5. Euthanasia |
|
|
Classical Stages/Planes of Anesthesia
STAGE 1 |
a. Begins immediately
b. Animal conscious, but disoriented c. Reduced sensitivity to pain d. RR & HR normal e. All reflexes present f. Very rapid stage |
|
|
Classical Stages/Planes of Anesthesia
STAGE 2 |
a. Begins w/ loss of consciousness
b. All reflexes present, but exaggerated c. Able to chew/swallow d. Yawning is common e. Pupils dilated, constict in response to light f. Excitement phase g. Appear to be fighting anesthetic, not under control h. Take care to prevent injury i. Ends w/ muscle relaxation, slower RR, decreased reflexes |
|
|
Classical Stages/Planes of Anesthesia
STAGE 3/Plane 1 |
a. RR becomes regular
b. Involuntary limb movements cease c. Ventral strabismus, pupils constricted, response to light diminished d. Swallowing reflex diminished enough to pass endotracheal tube e. **PALPEBRAL REFLEX STILL PRESENT f. Not a surgical plane of anesthesia |
|
|
Classical Stages/Planes of Anesthesia
STAGE 3/Plane 2 |
a. suitable for surgery
b. Surgical stimuli may increase HR/RR c. PLR sluggish d. Eyes central or rotated e. Respirations regular but shallow f. **PALPEBRAL REFLEX ABSENT |
|
|
Classical Stages/Planes of Anesthesia
STAGE 3/Plane 3 |
a. Deeply anesthetized
b. Significant circulatory & respiratory depression c. Excessively deep for Sx d. Respiratory assistance may be needed e. Increase in CRT, decrease pulse & HR f. Eyes central, moder. dilated g. Reflexes totally absent h. No jaw tone |
|
|
Classical Stages/Planes of Anesthesia
STAGE3/Plane 4 |
a. Spasmodic, jerky respirations, due to lack of coordination
b. Fully dilated pupils, No PLR c. Dramatic drop in HR & BP d. Pale MM, prolonged CRT e. Imminent cardiopulmonary arrest |
|
|
Classical Stages/Planes of Anesthesia
STAGE 4 |
a. Cessation of respiration
b. Total circulatory collapse and death c. Requires rapid CPR to save the animal |
