Swine Anaesthesia Flashcards
What are 4 unique challenges when putting swine under anaesthesia?
1) venous access difficult
2) ET intubation difficult
3) respiratory depression common
4) elevations of body temp common
Why is it difficult to keep swine temperatures from fluctuating?
1) low body surface area to body mass ratio
2) absence of sweat glands
3) malignant hyperthermia in genetically predisposed pigs
What is TKX combo?
Telazol-Ketamine-Xylazine
Telazol reconstituted with 2.5 mL xylazine (100 mg/mL) and 2.5 mL Ketamine (100 mg/mL)
What is the dose of TKX combo
0.5-1 mL/50lb
What is the Duration of TKX
20-30 min
What is the recovery time of TKX
60-90 min
What kind of anesthesia do you use for a c-section?
Lumbosacral epidural or spinal anesthesia
When do you use intratesticular injections?
castration
What types of inhalation anesthesia can you use on swine
Iso or Sevo
Mask induction or for maintenance through mask, nasal, or endotracheal tubes
5 Signs of Malignant Hyperthermia
1) Extreme muscle rigidity
2) increased temp
3) tachycardia
4) tachypnea
5) metabolic acidosis
Treatment of Malignant Hyperthermia
Dantrolene supportive care ( fluids, steroids, o2, body cooling)
How do you recover swine from anesthesia
- Administer oxygen and assist ventilation as necessary
- Position in sternal recumbency
- Place in well-ventilated, cool, and quiet environment
- Assess vital signs periodically
How can you be prepared for respiratory emergencies
1) Tracheotomy if necessary
2) Trachea may be very narrow – have variety of ET sizes
3) Respiratory stimulant available
