Terminology: • Anesthesia vs sedation • Injectable vs inhalant • Reversible vs non- reversible • Preanesthetic vs anesthetic
SAFETY • Anesthetic Gas effect on humans (VERY high exposure) • Abortion, genetic defects, cancer, organ failure Protect yourself: • Up to date system • Take all precautions
Anesthesia… Common side effects: • Depress breathing • Bradycardia • Hypothermia • Urination and defecation • Susceptible to seizures
Mechanisms of Anesthesia.. • Oxygen + anesthetic into rebreathing bag • Animal breathes in via rebreathing bag • Capillaries exchange Oxygen and anesthetic into bloodstream • Anesthetic reaches the brain
A normal anesthetic event • Preanesthetic • Anesthetic • Induction of anesthesia • Intubation • Maintenance • Extubation • Recovery
Recovery • Normal excitement phase Keep quiet and safe Monitor TPR, attitude Keep warm Monitor any surgical incisions
Preparation: • Endotracheal tube: What is it?? • What does it do?? • Check for: • Correct size • Check cuff
Rebreathing Tubes • What are they? • What is their function? • Choose: size • Non-rebreathing set up
Other options… • Anesthesia Mask • Induction Chamber
Rebreathing Bag • Reservoir of anesthetic gas and oxygen • Need to choose correct size based on weight or ideal weight of patient
Laryngoscope • What is it? • What is it’s purpose? • Check for: size, lightbulb, • function
Vaporizer • What is it? • What does it do? • Preparation: fill it
Sodasorb • Absorbs excess Carbon Dioxide • When granules are full, they turn blue • Change at least once a month
Oxygen Supply • Anesthesia travels via Oxygen • Flowmeter determines amount of oxygen flowing into system • Check tank every time you use machine • SAFETY TIP: Always turn OFF the Oxygen when you are finished
Scavenge System • What does it do? • OSHA requirements • F/AIR vs Scavenge system
Other necessities… • Gauze tie • Heated table/ heating pad • Eye lube • Syringe for cuff of ET tube
YOUR JOB….. • BE PREPARED!! • Monitor animal • Adjust anesthesia • Give breaths • Recover patient
